2HigH-Quality glulam timber made in germany HESS TIMBER is one of Germanys and Europes technical leaders in timber construction. The company, which is headquartered in Kleinheubach near Frankfurt am Main, offers a unique service range for demanding architects, planners and project developers in Germany and abroad. In addition to standardised services for timber construction, such as roof and industrial building structures for industrial and commercial construction, HESS TIMBER has also specialised in the planning and implementation of customised and architecturally demanding roof structures with unique geometries.
The plant grounds of HESS TIMBER Heavy load transport
HESS TIMBERs ability to cover the entire bandwidth of
services, ranging from planning, glulam products and
construction while maintaining the highest level of quality in
the execution of construction works is due to the fact that it
is probably the only company that combines an engineering
firm, glulam production, CNC beam production and its own
carpentry under one roof. In Spring 2010 HESS TIMBER took a
completely new and extremely fast processing finger-jointing
line concept into operation.
This high-tech production was supplemented in May 2010
with the worldwide first fully automated CNC-Press for curved
glulam beams. In 2006 the core of extensive investments was
a new CNC-controlled, 6-axis processing centre from Maka,
Nersingen and the finger jointing system was optimised with
an x-ray scanner and a modified charging system. Also new
was a high-frequency continuous press for length-independent
manufacture of glulam timber beams. HESS TIMBER now
ranks among the most modern glulam construction companies
in Europe and around the globe. By combining customised
engineering planning, state-of-the-art technology for
production, and the quality of its carpentry services, the
company is able to implement all of its clients requirements at
the highest quality.

a ComPany witH traditionThe company HESS TIMBER GmbH & Co. KG looks back on an impressive company history.
The general Manager Mathias Hofmann has been active in
the area of project construction of wood facade structures
since 2001 with his former company wohnwerk GmbH.
In 2005, he took over the business fields of the previous
HESS Holzleimbau Technologie (a company with 130 years
of tradition) and founded the new HESS-WOHNWERK GmbH
& Co. KG.
In 2010, the entity was changed to HESS TIMBER GmbH & Co.
KG. Very fortunately, the HESS knowledge continues to live
on with the new company. Also, since the new foundation in
2005, 50 additional jobs could be created. With its current 90
employees, HESS is proud of making a positive contribution to
the regional employment market situation.

4tHe benefits of glulam timber Glued laminated timber, often shortened as Glulam, is an engineered wood product manufactured by gluing together pieces of timber, known as laminates. This process produces larger size and longer length members, which can be curved or straight.
good lookingThe natural appearance of glulam is sufficiently attractive to
make it eminently presentable with no cladding indeed, used
as exposed beams, glulam adds to the aesthetic appeal of a
structure.
Chemical resistanceTimber and the synthetic adhesives used in bonding glulam
have a remarkable resistance to chemical attack and therefore
glulam is often chosen as the preferred structural material
for buildings such as salt barns, water treatment plants, etc.
Glulam is resistant to most acids, rust and other corrosive
agents.
HESS TIMBER has manufactured and installed many glulam
timber projects where steel could not been used due to
aggressive chemical environments like swimming pools, coal
storage buildings or salt storage buildings.
Even the harsh salty environment of the UAE is not an issue
for glulam structures. The timber canopies of the D1-Tower in
Dubai will show the advantage against steel which often needs
to be a special grade of stainless steel.
strength to weightA structural steel beam may be 20% heavier and a concrete
beam 600% heavier than an equivalent glulam beam.
Increased strength due to the laminating process glulam is
stronger than solid timber as it has fewer natural defects and a
wider distribution. It is also comparable to steel in strength but
is much lighter.

5great fire resistance When subjected to fire, large timber sections have greater
resistance to loss of structural integrity than steel or pre-
stressed concrete. This resistance is provided by a layer of
charcoal which forms around the surface of the section during
exposure to fire. The rate of charring of different species of
timber is known and therefore the performance and endurance
of timber in fire is predictable. The strength of the residual,
unburnt core of timber can readily be calculated, thereby
allowing a realistic assessment of safe resistance to fire to be
made. The method of calculation is given in DIN 4102.
As, on average, wood burns down at a rate of 0.7 mm
per minute, the cross section of the material is reduced
by approximately 20 mm in 30 minutes and by 40 mm in
60 minutes. This is why the load bearing potential of the
remaining cross section is of major importance. The respective
fire resistance grades F 30 and F 60 refer to the fire endurance
of these wooden members. It is interesting to note, after all,
that F 30 and F 60 can be obtained without additional flame-
retardant treatment. Due to the inherent material properties of
this natural building material, the fire-resistance characteristics
of wooden structural members are excellent.
As professionals know about the excellent fire behavior of
wood, many fire departments are timber constructions.
the renewable source fsC and PefCA small percentage of materials used in building construction
can be recycled but timber is the only renewable building
material. The planting rates are controlled to ensure growth
exceeds harvested quantities. In these countries there is more
standing timber than at any time since the ice age. This cycle
of felling and planting is very beneficial to the atmosphere as
it is only during growth that a tree absorbs CO2 and gives off
vital oxygen. Once a tree is mature this process virtually stops.
HESS TIMBER is FSC/PEFC certified and is entitled to use the
trademark FSC and PEFC.

environmentally friendlyA 305 mm x 165 mm steel I beam has the equivalent
performance of a 550 mm x 135 mm softwood glulam
beam but requires six times the energy cost to produce.
A comparable 400 mm x 250 mm reinforced concrete beam
requires five times the energy cost to produce. Add to this
the pollutant by-products of these wasteful processes and
steel and concrete structures are even more environmentally
undesirable.
energy efficientGlulam is also energy efficient in use. The well-known
insulation property of timber eliminates the risk of cold
bridging where the frame may penetrate external elements of
the structure. Its low thermal mass helps reduce fuel bills by
absorbing little space heating energy.
VersatileGlulam can be used for roof, lintel and floor beams, columns
and rafters in almost any type of structure.

wood sPeCies used for glulam timber The following species are showing a range of the most typical wood species which we use for our glulam projects. If you are looking for a wood species that is not shown here, please let us know. We are more than happy to offer you solutions.
softwood
European Spruce
Botanical name: Picea abies
European Spruce is an economically important coniferous
species grown in Europe and North America. It is used for
most of our products. Superior grades are prized as a premium
tonewood.
Radiata Pine
Botanical name: Pinus radiate
Radiata Pine is a softwood whose availability and ease of use
make it popular for all kinds of construction and decorative
uses. However, we only use it if specified by the customer due
e.g. pressure treatment requirements.
Radiata Pine is also used for the technically modified timber
named Accoya .
Western Red Cedar
Botanical name: Thuja plicata
Western Red Cedar is a large softwood that grows in British
Columbia and some of the nearby western states of the USA.
A versatile timber, it is commonly used for applications such as
cladding, windows and joinery.
However, there is no technical approval available for load
bearing purposes.

Douglas Fir
Botanical name: Pseudotsuga menziesii
Douglas Fir is one of the worlds best-known timber species.
Douglas Fir is a softwood timber, finding a range of weather-
protected applications in heavy construction.
European larch
Botanical name: Larix decidua
Larch is well-known as a tough and durable timber similar to
Douglas Fir (see above). It is also available as a knot-free timber
if premium quality is specified.
Accoya (modified timber)
Accoya is an acetylated long life wood made out of Radiata
Pine (see www.accoya.com). It is mainly used when it comes
to high performance requirements that might only be achieved
otherwise by tropical hardwoods.
Hardwood
European Beech
Botanical name: Fagus sylvatica
Beech is a relatively strong wood with high bending and
compression strength but it is not a durable wood and should
not be used if exposed to weather. However, Beech glulam
timber has its own technical approval and can therefore be
used for load-bearing glulam structures.
European Oak
Botanical name: Quercus
Oak is a hard, heavy wood, and has low stiffness and good
overall strength, making it increasingly popular as a structural
timber. Very similar in appearance and colour to the American
White Oak, European Oak has light-coloured sapwood and a
light to dark brown heartwood.
However, there is no technical approval available for load
bearing purposes. Despite this fact it can be combined very
economically together with our product HESS HyBRID.
