TWO PARTNERS - ONE VISION

BRITISH GYPSUM AND BINDERHOLZ

4

Every building is a symbiosis of different materials. A parti-

cular combination is the combination of cross laminated

timber BBS and dry-lining systems. The advantages of the

one material strengthen those of the other. Sustainability,

the careful use of resources and energy-efficient operation

of the buildings play a special role in these considerations, In

order to achieve this aim the companies combine their

know-how, their development potential and their consulting

expertise.

binderholz - system solutions in solid wood

In the 1950s Franz Binder senior turned his passion for wood

into a career. This passion continues now in the third genera-

tion of the family, with vision, innovation and great dedication

of all employees. binderholz produces sophisticated solutions

in solid wood at six locations. The responsible use of the won-

derful resource and the environment guarantees high quality

solid wood products and biofuels. binderholz provides for the

right raw material. The resource and energy-efficient proces-

sing ensures an ecological, cost-conscious and individual end

product. The energy and environmentally-oriented solutions

let wood be used with a clear conscience.

To create attractive living space and to

construct attractive and functional buildings,

that is the vision which connects

the binderholz building system

and British Gypsum Saint Gobain.

BI N DERHOLZ – I DEAS HAVE FREE REIGN

In the timber industry the name BINDER is synonymous with

traditional awareness and reliability, combined with high-tech

and innovation. 50 years ago still a small sawmill operation,

today binderholz is one of the leading European companies,

equipped with the most modern technology and manufacturing

methods and enjoying a corresponding reputation in the market.

Around 1,150 people are employed at five locations in Austria

and one in Bavaria. The products manufactured at these locations

are exported all over the world.

BRITISH GYPSUM - the leader among dry-lining systems

British Gypsum is an independent company of the Saint-

Gobain Group, a leading manufacturer of gypsum products.

Since the formation of the company in 1971 British Gypsum

has played a key role in the development of dry lining

systems in Austria. The company operates two open pit

mines: one in Puchberg at Schneeberg, where powder pro-

ducts are manufactured, and one at Grundlsee in the

Styrian Salzkammergut. This gypsum is processed in Bad

Aussee in one of the most modern plasterboard plants in

Europe. With its Customer Service and numerous innovati-

ons British Gypsum supports designers and building owners,

interest groups and business partners in their daily work.

This includes the special commitment to timber construc-

tion. As a founding member of BAU.GENIAL, British Gypsum

has supported the stronger promotion of sustainable wood

construction in Austria for many years.

binderholz cross laminated timber BBS

binderholz cross laminated timber BBS is multi-layered and

completely and solidly made from wood. A modern con-

struction material, a solid prefabricated component of wood,

heat insulating and can bear heavy loadings at the same

time, safe in fire and with good noise insulation, can be built

quickly without water and has a positive influence on the

well-being of people. The jointless surfaces and the cross-

laminated form design, guarantee stability and well-defined

building physics, fire and mechanical properties. BBS can be

universally used confidently as an integrated system with

great flexibility and can be easily combined with other mate-

rials. The surfaces can be left natural or colour-treated, clad

or are visible in various wood species.

Dry lining systems

Dry lining systems with plasterboard and gypsum fibreboard

have established themselves in the field of architecture both

in private and in public buildings for several reasons. Dry

lining systems are standardised, easy to install and yet allow

the realisation of spaces of sophisticated design. Because of

their composition gypsum products are suitable for solving

fire-technical, acoustic and noise insulation problems and can

be used as a durable element in damp rooms. British Gypsum

boards are recommended from the building biology aspect

and contribute to a comfortable room climate.

Solid wood and gypsum boards are ideal building materials in modern architecture. They draw on natural resources, are flexible, sustainable, and solve the promise of contemporary space formation in an outstan-ding manner.

BRITISH GYPSUM - A LEADER I N GYPSUM AN D DRY L I N I NG SYSTEMS

Since being founded in 1971 British Gypsum has built up an excellent reputation in the building materials industry. The newly built

board factory in Bad Aussee, which was commissioned in 1992, is still one of the absolute top plasterboard factories in Europe. Of the

production of more than 20 Million m2 gypsum board about 60 % is exported. British Gypsum has more than a quarter of a century of

experience in the production of gypsum board. The fact that the natural resources are protected to a maximum is a matter of course.

The strict rules we have imposed on ourselves go far beyond the legally required levels. Whilst the output of the factory in Bad Aussee

has doubled in the last ten years, the pollutant emissions have minimised to zero point and energy consumption has been reduced by

more than 30 %.

BENEFITS OF TIMBER CONSTRUCTION


6

Projects like the reconstruction of the earthquake region

around L'Aquila, Italy, provide impressive evidence of the

efficiency of the solid wood system construction. Of all con-

struction materials, wood features the best relation bet-

ween weight and load-bearing capacity. Timber construc-

tion is therefore most suitable to realize buildings on parti-

cularly difficult terrain, e.g. on a mountain ridge in Zillertal

in Tyrol, likewise roof systems from houses in central Vienna

which were build in the 19th century. Wood is the material

that is selected most often when it is a matter of passive

houses and houses with low energy consumption. And for

good reasons, according to the experts - wood succeeds in

complying with structural-physical requirements to the

greatest possible degree. Many opt for wood because of its

atmospheric characteristics: the agreeable surface tempe-

rature, its capacity to balance temperature and moisture

peaks. Likewise, wood - like plaster - exercises a positive

influence on the well-being of people and thus on their

health - which also constitutes an economic factor.

International surveys acknowledge that

timber construction has a great future.

While the ecological component has

constituted the decisive factor until recently,

solid economic arguments play an

increasingly important role now.

COST EFFICI ENCY

Since the tare weight of wood constructions is lower, the expen-

diture for the substructure and foundations is reduced. The high

degree of prefabrication makes processes at the construction site

easier and ensures a standardized and verifiable quality.

Construction site facilities can be kept on a smaller scale, the

expenditure in terms of logistics is lower. The dry construction

method shortens construction times substantially, thus making an

earlier use possible, which in turn reduces financing times.


7

The diversity of timber construction also lives from the material mix and the design potential. In many cases, the natural construction mate-rial of wood is deliberately made visible as a statement for state-of-the-art, eco-friendly and energy-efficient building.

SU BSTAI NABI LITY

Sustainability rests on three pillars: an economic one, an ecologi-

cal one and a societal one. All three have to harmonize with one

another if we really want to speak of sustainability. Building with

wood complies with all three requirements. Building with wood

makes economic sense. Both earnings and jobs stay put in the

region. Building with wood is ecological, because wood is a rene-

wable raw material. And building with wood is valuable for socie-

ty, because buildings in timber are optimized in terms of energy

and therefore affordable on a long-term basis.

PREFABRICATION

Timber construction elements are prefabricated to the greatest

possible extent, a fact that brings advantages in terms of quality

and deadlines. A constant air humidity and temperature prevail in

the production halls. The assembly operators work in good condi-

tions; the constructions are protected against effects of the wea-

ther. The work of subsequent trades like the electrical and sanita-

ry installations is prepared, so that the construction is carried

forward at the construction site both speedily and in a coordina-

ted way.

CO 2 N EUTRAL

Wood is a renewable raw material that has a great influence on

our climate. Trees convert CO2 and water into oxygen during their

growth. Wood used as a construction material, for derived timber

products and for furniture serves as a secure CO2 repository for

many years to come. Each cubic meter of wood that replaces

other building materials reduces CO2 emissions to the atmosphe-

re by an average of 1.1 tons.

TIME SAVI NG

Time saving through timber construction with binderholz BBS

cross-laminated timber in conjunction with British Gypsum dry

construction systems can be very substantial for the construction

of large-volume buildings. The high degree of prefabrication

shortens construction times considerably. Load-bearing wall ele-

ments just have to be shifted and connected to one another.

Drying times for brickwork or floor pavement are dispensed with

when British Gypsum dry construction systems are deployed.

Owing to their comparatively low weight, these prefabricated

timber elements can be dimensioned on a very large scale. Since

installations are laid in the hollow space between the plaster

board system and the timber element, there is no need for subse-

quent chiseling and plastering.

DURABLE, OF LASTING VALUE AND STABLE


8

Durability and stability of value

A long tradition in craftsmanship and industry as well as

targeted research created the experience in deployment of

the right product in a suitable way for diverse applications.

Austrian institutions and companies are global leaders in

the production and development of timber and derived tim-

ber products as well as in state-of-the-art manufacturing

and processing technologies. In modern timber construc-

tion, all companies that manufacture complete wall or cei-

ling elements are subject to both in-house and external

monitoring. In addition, many companies are voluntary

members of performance and quality associations. The qua-

lity of the derived timber products is ensured through defi-

ned standards and approvals. If wood is used correctly (con-

structive wood preservation), it is extremely durable.

Stability and lightness

Wood is characterized by a very high static quality. Multi-

storey buildings in timber and wide span structures consti-

tute the ideal areas of application. The reason for the high

degree of stability lies in the microstructure of wood, which

is responsible for high load capacity at a low tare weight. So

wood is a light construction material with excellent techni-

cal qualities. Notwithstanding its low weight, wood provides

a high degree of tensile strength and compression strength

and is resistant against the effects of weather when deploy-

ed correctly.

In relation to its tare weight, wood bears

14 times as much as steel; its compression

strength equals that of reinforced concrete.


BUILDING WITH SYSTEM

FI RE RESISTANCE TESTI NG

IIBS - the Institute for Fire Protection

and Safety Research has tested BBS

systems for load bearing and non-load

bearing building components also in

combination with British Gypsum

systems and classified their

functionality and safety.

NOISE I NSU LATION

All acoustic tests were carried out by

the ift Acoustics Centre in Rosenheim.

ECOLOGY

The Austrian Institute of Building

Biology and Ecology (IBO) and the

Institute for Building Biology Rosenheim

(IBR) regularly examine and assess

British Gypsum products, rate them as

harmless and certify them as recom-

mended construction material.

Ü-MARK AWARDED

The Materials Testing Institute of Stuttgart

University, MPA, confirmed with its certificate

dated 10. 10. 2006 the general construction

supervisory approval of BBS. Since then the

company may display the Ü-mark for its buil-

ding products.

Solid safety

Timber building systems with BBS and British Gypsum dry

lining systems meet all physical requirements of the standards

for load-bearing walls, ceilings and roofs. They are tested to the

European Technical Approval (ETA), carry the CE mark and

therefore may be marketed in Europe. These products are moni-

tored by third parties at regular intervals, and the systems are

further optimised. For this reason BBS elements are safe and

durable building products for a wide range of uses.

Combined with gypsum board

Load-bearing walls and ceilings, especially in public buildings

and multi-storey residential buildings must fulfil special

requirements, such as for fire safety. The RIGIDUR H gypsum

fibreboard is the only gypsum fibreboard with the fire protec-

tion classification A1, i.e., "non-combustible" in acc. with EN

13501. It meets all the requirements for cladding of interior

and exterior components. Because of these properties BBS is

often combined with British Gypsum board. British Gypsum

boards as a product without formaldehyde contamination

from binders meet the highest demands of building biological

criteria. The Institute for Building Biology in Rosenheim has

rated the RIGIDUR H gypsum fibreboard as a "building mate-

rial tested and recommended by IBR".

LICENCED TH ROUGHOUT EU ROPE

In 2006 BBS elements obtained the

European Technical Licence ETA-

06/0009.

In 2008 ETA 08/0147 attested the

British Gypsum gypsum fibreboard

RIGIDUR H as being fire class A1.

1. ENVIRONMENTAL PROTECTION

For binderholz and British Gypsum, environmental protec-

tion and environmental compatibility mean sustainable,

ecological responsibility in relation to human beings and

nature alike. That’s why products and production processes

are systematically guided by and continually developed

further according to ecological criteria. Construction with

wood makes sense in every way. In our part of the world,

wood is available as a natural and sustainable raw material

practically everywhere.

1.1. Sustainability

While growing, the forest absorbs carbon dioxide (CO2),

which is harmful to the climate, and thus makes an essential

contribution to climate protection. When one builds with

wood, the carbon dioxide stays absorbed on a long-term

basis and does not pollute the atmosphere. Beyond that,

very little energy is required for the production of timber and

derived timber products. Since wood and derived timber

products can be well-nigh completely reused, no large

amounts of waste are created that might have to be stored

at a waste dump. That also respects our environment.

The Austrian forest

The Austrian forest has absorbed approx. 800 million tons of

carbon (C). That is 40 times the amount of greenhouse gases

produced in the country in a year. The more wood, the bigger

the reservoir of carbon. The forest in Austria grows on 4 mil-

lion hectares, equaling 47 % of the country’s total area.

Around one billion solid cubic meters (1 solid cubic meter

equals around 1m3) of standing wood are available for use in

our forests. In this regard, Austria is among the leading coun-

tries in Europe; with regard to the standing wood per hecta-

re of forest area, it even has the leading position in compari-

son to the main European producers and markets. About 31

million cubic meters grow again per year. Only two-thirds of

that are presently harvested. The forest is the production

location for wood as a raw material and makes for clean

water, generates fresh air; it produces oxygen and thus a

balanced climate. Beyond that, the forest provides a living

space for numerous plants and animals. The forest is an

important water reservoir and produces high-quality drin-

king water through the filtering effect of the forest soil. The

forest filters dust and pollutants from the air and rain and

protects against erosion, flood waters and avalanches. The

forest as an eco-system can fulfill these multifarious func-

tions optimally only if its development is supported sustai-

nably and when human interventions in the forest comply

with its natural development stages. Austrian forestry has

been following this sustainable path for many years in a

groundbreaking way and with great success. Building with

local timber means investing in a healthy forest and thus in

an intact environment. No resources are wasted, and raw

materials are secured for future generations.

The Kyoto Treaty

Internationally legally binding targets for the reduction of

greenhouse gas emissions were determined for the first time

at the climate protection conference in Kyoto (Japan) in 1997.

In addition, the Kyoto Treaty codified the consideration of

forests as carbon sinks and the option for the trading of emis-

sions. The process of the determination of the many detailed

stipulations was concluded at the 7th member states’ confe-

rence in Marrakesh in 2001. 177 countries have joined or

ratified the Treaty or at least have consented to it since then.

Building with wood constitutes an essential component for

achieving the targets.

For more information on the Kyoto Treaty, see: www.unfccc.de

47 % of the total area of Austria is covered by forest (4 million hecta-res), corresponding to 1.095 billion solid cubic meters of standing wood. In this regard, Austria is one of the leading countries in Europe; with regard to the standing wood per hectare of forest area, it is even the leader compared with the main European producers and markets.

PEFC certification

All binderholz products are PEFC

certified. PEFC is the proof that

products come from forests that

have been cultivated sustainab-

ly; it aims at the conservation of

forests. This goal is to be achie-

ved through the promotion and

support of sustainable cultivati-

on. Strict criteria to which the cultivation of the forests is

aligned in conjunction with in-house monitoring as well as

an annual external on-site monitoring by an independent

certifier serve the purpose of complying with the goals and

guidelines.

EXAMPLES

❙ One cubic meter of forest is growing again in Austria every

second. This means that, in theory, a new timber house could be

constructed with the renewed material every 40 seconds. That

would be 2.160 houses a day and 788.400 houses a year, without

the existing forest being harvested.

❙ A 100-year-old Norway spruce tree, 30 m high, possesses half a

million green needles. The surface of the needles corresponds to

that of two football fields. With it, well-nigh 20 kilograms of CO2

are processed every day. So the forest plays an essential role in the

oxygen cycle. It absorbs carbon and reduces pollution by carbon-

dioxide greenhouse gases.

Each cubic meter of wood has absorbed around 900 kg of CO2!

The usage of wood as a sustainable raw material reduces the

increase of CO2 in the atmosphere and hence works against

the greenhouse effect. Trees absorb carbon dioxide and store

it as biogenic carbon over a long period of time. Each tree

trunk that has been used makes room for new trees and

increases the carbon reservoir in the wood. Without the uti-

lization of wood, e.g. in a forest that is not exploited, the

carbon that is stored will be emitted unused into the

atmosphere as CO2 through the decay of the trees.

Building with timber makes sense in every way. In our part of

the world, it is available everywhere and constitutes a raw

material that is natural and sustainable, of which more is

growing again than is harvested.

Photosynthesis enables the CO2 absorption

During photosynthesis, the tree absorbs CO2 from the air,

plus water and nutrients from the ground, while it grows

and builds the organic material wood from these compon-

ents. In the process, the low-energy carbon dioxide molecule

is broken down into a high-energy carbon atom and a high-

energy oxygen atom with the aid of light. The oxygen (O) is

emitted into the surroundings, whereas the carbon (C) ser-

ves for the organic growth of the tree and will be absorbed

for the rest of its life span.

Carbon sink

As already mentioned above, trees absorb huge amounts of

carbon dioxide while they grow. In times of rising CO2 emissions,

forests that are maintained and kept in balance by controlled

forestry, as they can be found all over Europe, constitute a vital

factor for the reduction of CO2 emissions. Thus they contribute

to a good and sustainable future. One could say that the carbon

is the scaffolding for the organic development of the tree (body

of wood); it will remain absorbed during the entire “life cycle”

that the tree has as a tree or as a building material. Only with

combustion or the natural decay of the wood is the carbon emit-

ted into the atmosphere again. Thus not only the forests but

also buildings, furniture or even toys made of wood are carbon

repositories and contribute to the reduction of the CO2 content

in the atmosphere. No matter in what way a tree is used, the

carbon remains absorbed in it for the entire life span of the pro-

duct. Thus the increased deployment of the CO2 neutral raw

material of wood as a building and construction material plays

a decisive role in the global reduction of CO2 emissions, which is

so urgently needed, and thus makes an essential contribution to

climate protection.

With the aid of solar energy, high-energy organic compounds are syn-thesized from low-energy, inorganic substances, mainly carbon dioxide and water during photosynthesis. In addition, oxygen is produced, which is vital for all living organisms.

EXAMPLES

❙ A total of 800 million tons of carbon are stored in the Austrian

forest alone. That’s 40 times the amount of greenhouse gases

that Austria produces in a year. The greater the amount of wood,

the larger the reservoir of carbon.

❙ If only 10 % of all houses in Europe were built with timber, carbon

emissions would be reduced by no less than 1,8 million tons

(around 2 % of the all carbon emissions).

❙ The devastating earthquake in L'Aquila (Italy) made 70.000 peop-

le homeless. The reconstruction was to be carried out using a

top-quality and earthquake-proof construction method. binder-

holz BBS came off as the winner of the international bidding pro-

cess. binderholz delivered a total of 11.000 cubic meters of BBS

cross-laminated timber and created 29.600 square meters of

living space with it. 52 cubic meters of wood grow again in the

Austrian forest every minute. So it took only 3,5 hours for the

wood that was delivered to L'Aquila to have grown again sustai-

nably. These 11.000 cubic meters of BBS store 9.900 tons of CO2

on a long-term basis.

❙ Each cubic meter of wood that replaces other construction mate-

rials reduces CO2 emissions into the atmosphere by an average of

1,1 tons. If you add that to the 0.9 tons of CO2 that are stored in

the wood, one cubic meter stores a total of almost 2 tons of CO2.

That equals the amount of what 1.000 Europeans or 5.000 cars

emit in a year.

CO2 balance across the life cycle of a building made of timber

PHASE 1 – PRODUCTION CHAIN: FROM THE TREE TO THE

PRODUCT

During the entire production, including harvesting of the

trees, manufacturing and processing of the products

(sawing, surface processing, assembly and so on), as well as

the transport to the construction site and assemblage there,

the energy expenditure (the so-called “gray energy”) is far

lower than with other building methods.

Source: Bauen mit Holz = aktiver Klimaschutz, Holzforschung Munich

PHASE 2 – USE

During the time of use, energy consumption, maintenance

and repairs play a essential role. Timber houses stand on the

highest possible level in terms of heat insulation. Wood

naturally contains air-filled cells by dint of which it conducts

heat and cold much less than other construction materials.

In winter, the cold cannot penetrate; in summer, the heat

stays outside. Even as a standard construction, timber

houses attain effortlessly the consumption values deman-

ded by law. With sufficient insulation layers, passive con-

struction and 3-liter construction can be easily realized for a

timber house. The low remaining energy demand makes

possible a heating facility that is correspondingly small

dimensioned. According to ÖNORM B 2320, correctly built

timber houses have an expected useful life of at least 100

years.

PHASE 3 – RECYCLING

Each piece of built-in timber has absorbed CO2 as carbon,

preventing it from getting into the atmosphere until the

wood will be made use of when it is converted into thermal

energy in a last recycling step. A timber house that has been

demolished after having concluded its useful life does not

leave a heap of unusable rubble, it leaves usable wood.

Individual construction components or elements can be

used again. The remaining wood will be used for the genera-

tion of energy. During combustion, only the amount of CO2

will be released that has been absorbed in the wood. The

natural carbon cycle is concluded.

Ecological, social, economical

The benefits of an energy-saving construction method are

crystal clear. On the one hand, the environment and climate

are protected; on the other, you can save money during the

time of use. So, in general, you can differentiate between

two kinds of energy-saving in construction. Firstly, in the

Federal states and municipalities alike have been advancing

the renovation of buildings in terms of heat insulation for

many years. Structural improvements are considered an

effective means for the reduction of CO2 emissions. Well

insulated solid wood construction components that can be

mounted on site in a very short time span present an intri-

guing alternative to established methods. There are hardly

any surface areas left for new buildings in densely populated

cities. Existing buildings offer a great potential for moderni-

zation and subsequent densification.

Existing buildings require construction methods that can be

implemented economically, swiftly, smoothly and precisely.

Timber construction offers solutions with different prefabri-

cation stages to attain this goal. The use of solid, prefabrica-

ted construction elements made of BBS does away with long

on-site construction times and leads to fewer disruptions of

the operation processes or the residential surroundings.

Alongside residential construction, it is mainly public buil-

dings like schools, kindergartens and administration buil-

dings that have to be renovated while they are operating.

Here the use of components that are as completely prefabri-

cated as possible offers decisive advantages.

❙ According to a survey conducted by the Versuchsanstalt für Holz-

und Trockenbau (VHT) in Darmstadt, Germany, the relevance of

the “gray energy” needed for the production and transport

of construction materials to the construction method, plan-

ning, required space and thus to the sealed surface area

that a house requires. Secondly, during the time of using

and maintaining a building, i. e. heating and cooling

durability and functionality. To build in an energy-saving

way does not only refer to the choice of construction mate-

rial. The proper planning and an in-depth examination of

the prevailing conditions are equally vital. Much argues for

the use of wood as construction material. It is a local resour-

ce and available in sufficient amounts, growing again “by

itself.” No other raw material uses less energy for its produc-

tion than wood does. And the same applies to storage and

processing. Naturally, wood processing consumes electrici-

ty, albeit the total energy balance is substantially lower for

the production of construction timber than with any other

construction material. Likewise, wood needs little energy

for transport. Wood is very light in comparison to its load-

bearing capacity, something that is a huge advantage for

transport - the weight of wood is one-fifth the weight of

reinforced concrete.

Construction on existing houses - renovating, modernizing

and densification with timber and dry construction

For construction on existing buildings, solid wood construc-

tion in conjunction with dry construction systems delivers

great advantages compared to other materials owing to the

possibility of prefabrication and thus shorter construction

times; the low weight; the positive CO2 balance and the

ecological profile.

Orderly dismantling - demolition

When analyzing the waste production, a reduction of the

waste production can be seen in the scenarios of an expan-

ded application of timber construction methods. Moreover,

the waste they produce indicates a great exploitation poten-

tial in terms of material and energy; the exploitation effici-

ency can be even heightened through the development of

exploitation-compatible construction methods. The choice

of material today has an impact on the waste of tomorrow.

So already in the planning process it has to be ensured that

material is integrated in such a way that they are easily avai-

lable and can be optimally recycled as materials (“design for

recycling”) or for the generation of energy (“design for ener-

gy”) at the end of their life cycle. In this context, timber

construction proves beneficial, since wood can be more

easily manipulated; ideally, it can be dismantled and reused

as a complete, high-value construction component. For

wood, the exploitation for the production of energy and the

effects this has on the replacement of fossil energy sources

stands at the bottom of the list. The wood construction

method thus has a great potential for saving material and

energy resources.

1.3. Recycling

57 % of the entire waste production in Austria derives from

building activities. The waste of remaining masses from

building (building rubble, concrete demolition and so forth)

amounts to around 5 million tons/year (= 18 % of all building

waste). The so-called building site waste accounts for the

smallest portion in the total building waste, with another 4 %

(1.1 tons/year). Waste cannot be completely avoided but can

be recycled to a large extent. Up to 90 % of building site

waste can be avoided by recycling. Wood and plaster are

ecologically recyclable; they can reenter the production pro-

cess or can be used a second time or be made further use of.

The products environmentally compatible material

underscores their recyclability.

EXAMPLES

❙ One can gain around 3 cubic meters of dry wood chips from

1 cubic meter of BBS, which can be processed into derived timber

products or converted into thermal energy as a premium combu-

stion material. In comparison with other materials, the produc-

tion of wood requires only small amounts of energy.

❙ The deployment of the dry construction system is disproportiona-

tely growing - yet not the construction site waste. Through con-

trolled recycling, plaster board remains are reentered into the

production process. Constructions completed in the dry construc-

tion method demand already upon assembly much lesser volu-

mes than established methods.

1.4. Complete production cycle at binderholz

Within the production plants of binderholz, the log wood

that has been delivered is completely processed into trim-

med timber, solid wood slabs, glued-laminated timber, BBS

cross-laminated timber, MDF slabs and biomass fuel. Our

own biomass cogeneration plants provide the energy supply

at the operations. Hence binderholz products make a contri-

bution in a multitude of ways to the reduction of CO2 emis-

sions and thus to climate protection.

Alongside a complete range of solid wood products for innovative timber construction, binderholz produces biomass fuel and medium density fiberboard. Thus it guarantees that the resource of wood is 100 % processed.

2.1. Fire Protection

In the event of fire building components must retain their

function for a specified period of time. The performance of

a component depends on the interaction the supporting

structure, the cladding and the insulating materials. For

fire protection the fire resistance period of a structure is of

particular importance. Requirements for fire protection

are defined by the fire rating. Moreover, there could be

additional requirements on the incendiary class. Timber

has the ability in the event of fire to form a protective

layer, the so-called carbon film. It prevents or delays bur-

ning and acts against the fire spreading.

Combustibility of building materials: The fire behaviour of

building materials is classified, including the smoke-and

droplet formation, according to the new EN 13501-1. The

new legislation includes, among other things, seven clas-

ses for the fire performance of wall and ceiling finishes

(A1, A2, B, C, D, E and F).

Fire resistance of building components: In considering the

fire resistance classes not the building materials but com-

plete components are investigated. Depending on the

duration of

❙ F30 fire retardant, 30 minutes fire resistance

❙ F60 highly fire retardant, 60 minutes fire resistance

❙ F90 fire resistant, 90 minutes fire resistance

❙ F180 highly fire resistant, 180 minutes fire resistance

The new classification standard EN 13501 part 2 differenti-

ates according to the following performance features:

❙ R Load bearing capacity

❙ E Room closure

❙ I Thermal insulation

as well as W (radiation), M (resistance), C (self-closing

property) and S (smoke tightness).

The fire resistance times are graduated as follows: 15, 20,

30, 45, 60, 90, 120, 180, 240, 360 minutes

Load-bearing elements are identified with the load applied

during the test. The combination of the properties in

terms of load bearing capacity, the room closure and the

thermal insulation are laid down in the following classes

to the previous fire resistance classes.

Customary component classifications in timber are: REI

30, REI 60, REI 90 for load-bearing and EI 30, EI 60, EI 90 for

non load-bearing construction.


BBS cross laminated timber burns defined with a burning

rate of about 0.7 mm per minute. This was determined by

extensive testing. Therefore the fire-resistance of BBS can

be very accurately calculated. In the fire testing not only

the BBS elements were investigated, but also the element

connections. The element connections are gas-tight and

smoke-tight and prevent fire penetration. Benefits that

not every material can claim. It is therefore understandab-

le that fire-fighters prefer deployment in wooden buil-

dings to other types. Because they know how long they can

stay in it without endangering themselves.

Most fire victims do not burn to death. They succumb to

flue gas poisoning. In order to minimise flue gas leakage

with BBS, all longitudinal layers of the BBS elements are

made from single layer boards over the whole area.

If there is a fire on one side of the BBS, then in 60 minutes only 9.5° C penetrates the 10 cm thick BBS to the other side.

The task of the noise insulation is to adequately protect peop-

le from noise. In timber construction the components always

consists of several layers. In this way multiple resistance

stands in the way of the noise on its way through the compo-

nent. Whilst the noise insulation of single-layer components

is based only on its mass and rigidity, multi-layered construc-

tion with decoupled shell and cavity insulation in timber

construction achieves the same noise insulation values with

significantly lower masses.


With solid wood construction the total thickness of the cross

laminated timber, the area weight and bending rigidity play

the key roles for the noise insulation of the base member

(without further layers). Generally, the entire component

(wall, ceiling, roof) is usually complemented by additional

layers (façades, services installations, floor construction, etc.).

The noise insulation of the entire component is significantly

increased by cladding. BBS cross laminated timber compon-

ents are fabricated from individual component parts. These

components are coupled together on site by defined connec-

tion systems. The design-related element connections are

extensively tested and designed so that they have no negative

influence on the specified sound reduction.

For the use of BBS as a separating floor, systems with impro-

ved noise insulation were developed in cooperation with ift-

Rosenheim. The results clearly show that the optimised struc-

tures stand up well in comparison with reinforced concrete

floors and are one-fifth of the weight.

BRITISH GYPSUM DRY LINING SYSTEMS

Flexible layers with high surface mass, such as gypsum board,

contribute advantageously to the noise insulation. The noise

insulation at high and middle frequencies can be increased

even further by the provision of an additional services instal-

lation level. Care should be taken to use soft resilient support

profiles (for example, spring track), heavy, flexible boarding

(e.g., British Gypsum fire protection boards) and a large as

possible spacing between the skins. If dry floor screeds of

several layers of large-format boards are laid and are fixed

with adhesive over the whole area (z. B. British Gypsum

Rigiplan dry screed), then soft impact noise insulation can be

used accordingly. The lower the dynamic rigidity, the better

the noise insulation.

British Gypsum dry lining systems

For fire protection the fire resistance period of a structure is of

particular importance. When the fire is inside, this is determi-

ned mainly by the internal cladding system. Gypsum boards

contain crystal-bound water contents, which in the event of

fire act as "extinguishing water".

For a detailed fire safety plan the following must also be con-

sidered:

❙ cladding facing away from the fire ensuring integrity of the

room

❙ insulation: contribution to fire resistance, particularly

temperature penetration

❙ Load-bearing construction: maintaining load bearing

capacity, as far as possible minimising deformation caused

by temperature

❙ Building element connections: Prevent the fire spreading

and fires in cavities, room integrity, smoke and gas tight

Therefore, the fire resistance of a construction are only deter-

mined and reported for the entire construction and not for

individual parts.

British Gypsum has innovative solutions for cable penetrati-

ons and service openings in its programme. The fire protec-

tion effectiveness of a compo-

nent depends to a large extent

on the execution of the details.

Non-tight pipe penetrations,

wrongly made power socket

details or non-tight ceiling con-

nections result in the loss of the

intended fire protection.

EXAMPLES

❙ The water contained in BBS cross laminated timber evaporates in

the event of fire. 1 m3 BBS contains around 50 litres of stored

water.

❙ Gypsum boards contain crystal-bound water content, which acts

as extinguishing water in the event of fire. A 15 mm British

Gypsum board contains approx. 2,5 l/m2

Structure-borne sound is sound that propagates in a solid body, such as the transmission of oscillations in buildings.

Airborne noise insulation

Sound transmission causes the structure to oscillate. All

material layers are involved in sound transmission. For the

transmission of vibrations in timber building components,

the surface mass of the planking and the nature of the fixing

are important. The insulation in the cavity affects this cou-

pling of the individual layers and the propagation of sound

within the cavity. The evaluated sound reduction index Rw'

[dB] indicates the airborne noise insulation of a building ele-

ment

between two rooms. The noise insulation of multilayer com-

ponents depends on the vibration characteristics of each

layer and the interaction of all layers. The characteristics of

the individual layers are dependent on their area mass (iner-

tia) and the bending rigidity. Flexible layers with high surface

mass, such as gypsum board, contribute advantageously to

the noise insulation. The noise insulation at high and middle

frequencies can be increased even further by the provision of

an additional services installation level.

In insulating materials the porosity is critical. In multi-shell

structures a large portion of the sound energy is transmitted

via the coupling of the individual layers.

The noise insulation can be improved inter alia by:

❙ lthe reduction of the connection points (check

statically necessary clearances)

❙ the change of screw torque (as with resilient connections,

such as clips instead of screws)

❙ the use of soft resilient support profiles (for example, spring

- rails, wall linings on metal studding)

❙ the use of heavy, pliable cladding (such as gypsum board

materials)

❙ complete filling of the cavity with insulation

❙ Increasing the distance between the skins.

Structure-borne sound/impact sound

Structure-borne sound is induced in a building component by

mechanical stimulation.

Impact sound is a structure-borne sound caused for example

by walking, children hopping or knocking. The noise is mecha-

nically introduced directly into the floor slab and radiated in

the adjacent rooms. The insulation of a floor slab is indicated

by the evaluated standard impact sound Ln,T,w' [dB]. The con-

struction situation

is indexed here by a dash, which shows that Ln is a standar-

dised impact sound level. In an impact sound measurement,

the floor construction is stimulated by a standard tapping

machine and the noise level generated in the adjacent room is

measured. The weighted standard impact sound level can be

determined, taking into account the reverberation time. The

lower the level, the better the floor is in acoustic terms.

Decisive for the structure to be chosen are:

❙ the dynamic rigidity s' of the impact noise insulation

❙ the mass of the screed and the structural slab

The lower the dynamic rigidity s', the better the noise insu-

lation. If dry floor screeds of several layers of large-format

boards are laid and are fixed with adhesive over the whole

area (i.e., the screed is sufficiently rigid), then soft impact

noise insulation can be used accordingly. The greater mass

of the dry screed helps to improve the impact noise insula-

tion. Also with the impact noise measurement the building

situation is significant. The acoustical property of a floor is

always to be assessed including the secondary paths.

Measurements are taken on site to ensure the quality of the workmanship.

2. BUILDING PHYSICS

In essence, it is attempted to prevent or minimise the intro-

duction of impact sound in the design, transmission and

dissipation. The dissipation in the reception room can be

reduced by wall linings or generally by flexible cladding.

Flank transmission / secondary sound paths

With the noise insulation between two rooms, apart from the

partition wall also all adjacent components are involved. The

partition wall is just one of many paths of transmission. In

highly sound-absorbing structures, the sound is transmitted

mainly via the flanking ceilings, roofs, interior and exterior

walls. For the optimisation of the sound insulation of compo-

nents a very low secondary path transfer is desirable. For the

assessment of noise insulation the given construction situati-

on is significant, i.e. with the acoustic requirements a separa-

ting component will always be assessed including the

secondary paths. The specified sound reduction can only be

achieved by compliance with installation rules and considera-

tion of the connection details.

Structurally, the introduction of impact sound in buildings is

usually prevented by appropriate floor coverings, such as a

floating screed, and transmission through bearings on elastic

intermediate layers and by the incorporation of damping lay-

ers. Detailed investigations by the Austrian Timber Research

Association confirm that suitable linings and suspended cei-

lings can be reduced or done away with altogether Generally,

the sound flow of secondary sound paths can be reduced by

flexible soft, decoupled cladding. The extent of the secondary

path transmission depends on the specific construction situa-

tion.

The noise insulation of flanking components is essentially

described by the following values :

Airborne sound:

RL, Rij (DIN 52217)

Dnf (EN 12354-1)

impact sound:

Lnf (EN 12354-2)

For test stands with no flank transmission the sound trans-

mission through secondary paths is suppressed by appropri-

ate measures. The transmissions via the flanks can be deter-

mined by separate measurements as noise insulation measu-

re or standard flank level difference according to EN ISO 10848

or DIN 52210 -7:1997-12. For measurements in completed

buildings, the components with the actual connection condi-

tions and related transmission paths are to be examined.

Measurements in completed buildings are referred to as qua-

lity tests and are used to demonstrate the attaining of the

required or specified noise insulation.

The possibility of repair or reconstruction of components on

the site is extremely low and is associated with substantial

costs. Therefore professionals with experience in timber con-

struction should be involved early in the design of projects

with higher requirements.

Thermal insulation in winter

Heat insulation in buildings includes all measures to reduce

the heating demand in winter and cooling demand in sum-

mer. The main focus is on increasing comfort due to a ple-

asant room climate and the associated significant environ-

mental benefits. Insufficient insulation may give rise to

uncomfortable and unhygienic indoor climatic conditions.

The minimum requirements for the insulation of the con-

struction are laid down primarily in the building regulations

of the states. Additional requirements for low energy and

passive buildings are set out in the corresponding funding

guidelines.

Why insulation?

❙ to enhance comfort

❙ to prevent illnesses

❙ to save money, as heating costs will be substantially reduced

❙ Increase in value of the building (energy costs)

❙ to protect the environment, as the CO2 emissions are

reduced considerably


With BBS low energy, passive energy and plus energy buildings

can be constructed. BBS structures achieve all the usual ther-

mal insulation values and due to the diffusion open construc-

tion and the fact that they can reduce the peak values of indoor

humidity, lead to a comfortable and balanced indoor climate.


Modern wooden buildings as passive houses and multi-com-

fort house construction with systems from Saint-Gobain

guarantee highest quality. Saint-Gobain insulating materials

has an extensive range of products for floors, walls, ceilings

and roofs. The products range from the normal thermal insu-

lation up to complete system solutions for the home as well

as commercial and public buildings.

Mineral fibre insulation from ISOVER with a λ of 0.032

W/mK and WDV Systems from Weber with a λ of 0.022

W/mK offers highest comfort with least thickness of insula-

ting material. British Gypsum wall linings and suspended cei-

lings and roof constructions with full cavity insulation (for

example, ISOVER mineral wool) also contribute to the reduc-

tion in the U-values of building elements.

The dry interior construction makes a significant contribution

to the required improvements of energy efficiency, also in

existing buildings. As part of the development of existing roof

space the energy efficiency of existing buildings can be impro-

ved significantly. In addition to the short construction time a

particular advantage of the dry construction method lies in

the accompanying opportunity to renew the technical instal-

lations of the building.

In addition, cladding of British Gypsum boards with a density

of approx. 800 to 1300 kg/m2 contributes to increasing the

storage capacity of the mass of the building component and

the comfort in the summer.

Thermal protection in the summer

The summer heat protection (thermal protection) serves to

keep the heating up inside the building, which is usually due

mainly to sun streaming in through the windows, to a tolerab-

le level. This is done primarily by minimising the heat input

from direct sunlight, heat conduction from the wall, roof and

ceilings and the waste heat from electrical equipment and

people. Windows with no sun protection have the greatest

impact on the heating of the interior.

Summer heat protection becomes more and more important

as a result of global warming and the tendency to rising tem-

peratures. Associated with this is increased use of air conditio-

ners, which in turn increases the electricity / energy consump-

tion and thus the CO2-emissions particularly in the summer

months.

Summer heat protection must therefore be taken into account

already in the building design to prevent the risk of overhea-

ting of the building in summer resulting in uncomfortable

room temperatures. In residential buildings, due to night

ventilation, low heat output from appliances, sun protection

and heat storage, in the average summer room temperatures

will remain below 27° C. In hot periods, they may rise slightly.

In offices the aim is for temperatures below 26° C. It is parti-

cularly important on the one hand that attention is given to

installing sun protection on the outside of windows in order

to avoid the "greenhouse effect", and on the other to under-

stand and take account of the summer behaviour of buildings

and especially of the users. Not only the maximum tempera-

ture occurring, but also the duration in which a certain tem-

perature threshold is exceeded, is important for the subjective

perception of the user. The influence of user behaviour on the

room temperatures in summer taking into account various

building materials and construction - lightweight, brick, con-

crete - was investigated by measurements of occupied proper-

ties as part of a research project.

Parameters that influence the behaviour of non-active air-

conditioned buildings in summer and the internal heating as

a result of summer heat exposure are:

❙ the outdoor climate

❙ the thermal properties of the components used outside,

such as for example surface colour, thermal insulation

capacity, construction of the components, component

assemblies and sequence of layers, the heat storage capacity

in particular of internal components, the total energy

transmission, the size and orientation of the glazing used,

existing solar protection systems and their effect

❙ orientation of the external wall surfaces

❙ the use of night ventilation possibilities and sun protection

❙ the release of heat from electrical equipment,

lighting and people

❙ Storage effectiveness of furnishings and

the building construction

The results of the research project showed that regardless of

the construction, the materials used and the existing internal

storage mass, the user behaviour and especially the incorrect

use of ventilation possibilities has a major influence on the

development of summer room temperatures. Here, the noc-

turnal heat dissipation through the windows is crucial to the

summer heat behaviour of rooms.

Reasons why in summer airing is not carried out:

❙ The assumption that with passive houses ventilating at

night is not necessary

❙ risk of falling from children's rooms (restriction to tilting of

the windows)

❙ Reduced ventilation effect through insect screens

❙ Pets (windows are restricted in tilting.)

❙ Ground floor apartments (windows are limited in tilting for

security reasons.)

❙ Restriction of the ventilation effect in the apartment

due to closed internal doors

❙ Ambient noise, especially at night

The summer building behaviour can be sufficiently depicted

with the newly released ÖNORM B 8110-3, in which all relevant

processes are shown.

Surfaces of wood and plaster provide a comfortable indoor climate inboth winter and summer.

In summer, the daily fluctuations of the outside air tempera-

ture are generally higher than in winter. In addition, there is a

very high temperature difference on the component surfaces

as a result of sun exposure.

Measures for optimisation:

❙ increase thermal insulation

❙ external layers of insulation and internal storage

capacity mass affect the interior temperatures favourably.

❙ Choice of window. According to recent building physical

studies the thermal transmittance of windows has a much

greater influence on the indoor temperature than the heat

storage capacity of the internal masses.

❙ The type of insulation material selected is not so

important. Rather, the thickness of the insulating layer and

the type and thickness of material of the lining of the interior

stand at the forefront of considerations.

❙ Correct user behaviour. By nocturnal ventilation and

closed windows and doors during the day the

indoor climate can be further improved.

The results of scientific studies show that the summer heat

protection can only be partly equated with the storage capaci-

ty of the building components. With increasing thermal insu-

lation levels, summer temperatures in the room sink to a

comfortable level. BBS elements have a positive effect here, as

BBS simultaneously insulates well against heat and stores it

excellently. The simulation of a single-family house shows that

with increasing thermal protection, temperature excesses are

less frequent and weaker. Also the accumulated experience of

residents shows that the comfort and indoor climate in woo-

den buildings in the summer are consistently judged positively.

2.4. Living environment / healthy living


Wood is open to diffusion and therefore allows the natural

movement of water vapour through components. This positi-

ve building physical property of BBS and its ability to absorb

humidity without damage (absorption characteristic), are

crucial factors for a comfortable and balanced climate.


British Gypsum air-conditions the room. Gypsum board has a

high proportion of pores that absorb dampness and store

moisture at a time of increased humidity in the room. In dry

air they release the moisture again to their environment. In

this way the indoor climate is regulated automatically. British

Gypsum boards contain no health-damaging substances such

as heavy metals, biocides, formaldehyde, or fine dust. For this

reason the products are recommended as building materials

by the Institute for Building Biology, Rosenheim (IBR), and the

Austrian Institute for Building Biology and Ecology, Vienna

(IBO).

Moisture regulation

Wood as a natural and renewable resource has many positive

physical properties. One is the ability to absorb moisture and

to release it again. In this way BBS has a dampening effect on

peak values of room humidity. 1 m3 BBS at a room air tempe-

rature of 20° C and a relative humidity of 55 % stores about 43

litres of water. If the relative humidity changes from 55 % to

65 %, then 1 m3 BBS absorbs about 7 litres of water from the

air in the room.

Water vapour diffusion

The full area adhesive joints of BBS are permeable. Tests by the

adhesive manufacturer show that the usual glued joint has the

same diffusion resistance as a 35 mm thick pine board. BBS is

therefore permeable but works as a vapour barrier. These two

positive features are important criteria for a comfortable indoor

climate. The bonded single layer of BBS has no influence on the

diffusion behaviour of the whole construction. Basically con-

struction is carried out without vapour barriers or dpc's.

The suitability of the overall component is to be proven in each

case. All constructions given in this brochure have been chek-

ked physically.

Convection

Due to the full area bonding of the BBS elements there are no

voids which might enable convection to take place. When

installing fixtures, care must be taken that the construction is

executed air-tight to prevent leaks by convection.

3. CONSTRUCTION

The noise insulation properties of BBS meet all normative

requirements. The visible surfaces in spruce, larch, Douglas

fir, white fir or pine, can be planed, sanded or brushed fini-

shed. The top layers are seamless single layer boards with

board character. For the warmth and comfort of building

occupants it is essential that the surface temperature of the

BBS is near room temperature. This uniform temperature is

considered to be pleasant, even when the room temperature

is slightly lower. A further contribution to greater well-being

and energy efficiency of the building.

Outer wall / inner wall / partition wall

BBS elements are used as exterior walls, interior walls and par-

titions. The cut outs for electrical installations can be carried

out in the factory.

BBS elements meet all criteria for traditional

construction, they achieve the fire resistance

REI 30-90, can be used for load transfer and

they increase the storage mass of a building.

3. CONSTRUCTION

The individual elements have a strong reinforcing effect

thanks to their crossed layer structure. For this reason, they

can fulfil both load-bearing and bracing functions. Wherever

earthquake-proof construction is required BBS has another

important advantage: The element joints, which can be

screw fixed, can absorb and attenuate dynamic movements.

Roof

BBS cross laminated timber can be used in every type of roof.

The great advantage of the roof elements is the short con-

struction time of only a few hours. This enables quick water

tightness and finished visible surface on the inside. With BBS

typical residential or commercial construction spans can be

carried out economically. The elements also take on a rein-

forcing function. BBS roof constructions fulfil safe and sound

all structural, fire and acoustic requirements. The summer

heat protection (protection against overheating of the buil-

ding in summer) is optimally solved with BBS. The mass of

wood optimally counteracts the temperature development.

Floors

The BBS floor elements in combination with British Gypsum

screed and British Gypsum ceiling systems with their multi-

layered structure meet all the requirements of a separating

floor. Because of the special layer structure of the BBS ele-

ments the floor elements act as stiffening floor slabs and

take on load-bearing functions. The shrinkage and swelling

of the wood is negligible due to its multi-layered, cross-

bonded construction. For this reason, the individual ele-

ments can be laid without expansion joints. Due to the dry

construction with British Gypsum screed elements, the floor

elements can be walked on and loaded immediately after

laying. The standards approved structures can be carried out

in fair face quality.

Stability

The load transfer in panels of cross laminated timber ele-

ments is via the crosswise glued wood element. Designed as

a flat element, a plate effect can be assumed. The fibre direc-

tion of the surface layers is to be observed when calculating

the load bearing capacity. The transfer of the shear forces of

individual elements should be ensured by appropriate

measures. The characteristics and parameters can be found

in the BBS certification. The structural analysis programme

may be obtained from www.binderholz-bausysteme.com.

Project specific preliminary design and drafting of fixing

details are offered by binderholz Bausysteme.

4. APPENDIX

4. APPENDIX


The purpose of European standardisation is to ensure that

all construction products traded freely meet clearly defined

criteria with regards to their intended use and are identified

accordingly with the CE mark. It should therefore be ensured

within the scope of national standards and legislation that

these construction products are used and installed in accor-

dance with their intended purpose. The construction pro-

duct directive concerns products that are installed in buil-

dings as permanent fixtures and contribute towards the

fulfilment of an essential requirement (e. g. fire protection,

noise protection, mechanical resistance and stability) in

buildings.

For detailed information see www.dibt.de or www.oib.or.at.


Building regulations basically remain unaffected by changes

to European standards. References to changed standards

need to be updated in the course of document revision.

However, their essential content - i.e. regulations in the

sense of amendments to applicable standards and require-

ments for implementation - remains intact.

4.3. Standards

❙ EN 1991: Actions on structures (EUROCODE 1)

❙ EN 1995: Design of timber structures (EUROCODE 5)

❙ EN 1998: Design of structures for earthquake resistance

(EUROCODE 8)

❙ DIN 1052: Design of timber structures

❙ DIN 4074: Strength grading of wood

❙ EN 338: Structural timber - Strength classes

❙ EN 13501: Fire classification of construction products and

building elements

❙ ÖNORM B 8115: Sound insulation and room acoustics in

building construction

❙ ÖNORM B 2320: Wooden residential houses

❙ DIN 18180: Gypsum plasterboards

❙ DIN 18181: Gypsum plasterboards for building construc-

tion - Application

❙ DIN 18182: Accessories for use with gypsum plaster-

boards

❙ ÖNORM B 3410: Plasterboards for dry construction systems

❙ ÖNORM B 3415: Gypsum plasterboards and gypsum pla-

sterboards systems - Rules of planning and use

❙ EN 13581-2: Fibre-reinforced plasterboard


Certified structures are described in certificates and appro-

val documents in the form of illustrated descriptions. The

materials listed for each system solution are binding and

cannot be replaced by other or similar materials. It is not

possible to provide an in-depth explanation of the details in

this brochure. The following therefore applies: The corre-

sponding certificate, inspection report or approval docu-

ment should be consulted in conjunction with the imple-

mentation of any design contained herein. The use of diffe-

rent components may be possible in certain cases. Please

contact our Technical Service department.
