THE BENEFITS OF LAMINATED GLASS
PVB (Polyvinyl Butyral) laminated safety glass makes it
significantly more difficult for criminals to break through. It also
prevents a simple fall against a large window from turning into a
tragic accident. In addition to these well-proven safety and
security benefits, laminated safety glass blocks noise and harmful
UV radiation.
Laminated glass is available in three performance variations:
Ÿ Normal Strength (NS) for human impact safety (1 x 0.38mm PVB Interlayer)
Ÿ High Penetration Resistant (HPR) for additional security (2 x 0.38mm PVB Interlayers)
Ÿ High Impact (HI) for security in high-risk applications (4 x 0.38mm PVB Interlayers)
THE BENEFITS OF LAMINATED SAFETY GLASS
The toughness and resilience of laminated glass makes it an
excellent safety glazing material. In vertical or sloped applications,
laminated glass can resist penetration from impact. If the glass is
broken, fragments will adhere to the PVB interlayer, reducing the
risk of personal injury and property damage.
All 0.38mm and 0.76mm National Glass Distribution PVB, carries
the SANS 1263 – 1:2013 mark. This standard requires that a 45kg
swing bag is dropped through a pendulum arc from a height of
450mm and strikes the centre of the test pane with an impact force
of 203 Joule. The impact of the swing bag should not rupture the
vinyl interlayer to allow 75mm sphere to pass through it.
Laminated glass offers greater protection for people and
properties over other glass products. The standard two-ply
construction provides resistance to penetration when subjected to
attempted forced entry. In multiple configurations, laminated glass
can even resist bullets, heavy objects, or small explosions.
As per SANS 1263 – 2:2007, our 1.52mm High Impact Laminated
glass is tested by repeatedly dropping a 225g steel ball from a
height of 9m. The impact of each drop is approximately the same
as a blow from a hammer. The table shows the number of blows
required to penetrate the glass.
NB: The size of the hole at penetration point is approximately 50mm in diameter. Many more blows are required to gain access.
The sound damping performance of the PVB makes laminated
glass an effective sound control product. Laminated glass is
commonly used in airports, museums, sound studio and schools
to reduce unwanted noise from aeroplanes, heavy machinery and
traffic, to name a few. National Glass Distribution manufactures
Acoustic PVB, using a special 0.76mm sound absorbing acoustic
vinyl.
Laminated glass offers unique combinations of clear or tinted
interlayers and solar heat reflecting coatings which can serve to
reduce the harsh effects of glare and solar radiation. This creates
comfortable conditions for the occupants of buildings.
The ultraviolet (UV) filtering performance of the polyvinyl butyral
interlayer helps protect valuable furnishings, displays or
merchandise from the fading effects of UV radiation. The ISO
Damage Weighted Transmittance (Tdw-ISO) values illustrate the
performance of the glass to reduce fading by taking into account
the transmittance of both UV and visable light in the wave lengths
from 300 to 600 nanometers. An example in the table below shows
the comparison between Clear laminated and a PVB Grey
Laminate. The reduction of damaging radiation improves by 50%
Laminated glass can help provide protection from injury and
property damage from man-made or natural disasters. By keeping
the glass intact within the frame, laminated glass helps reduce
injuries from large shards of flying glass caused by, for example
hurricanes, earthquakes or other unusual loading on the glass.

TINTED PVB LAMINATES
Tinted laminated glass products are made from various
combinations of clear and tinted glasses and PVB interlayers.
Tinted laminates are available in a wide range of colours to meet a
variety of aesthetic, glare reduction and solar control demands.
Coloured and patterned interlayers can be used individually or in
various combinations to create colourful and distinctive glass
facades, partitions and interiors.
Because the patterns and colours are encapsulated between
layers of glass, Tinted Laminates are easier to keep clean than
sandblasted glass, and it does not peel like applied vinyl. Tinted
Laminates reduce damaging short-wave ultraviolet radiation and
offer additional safety, security and noise control benefits. The
lighter tints eliminate some solar energy and are intended for use
in glazing areas where safety, glare control and aesthetic qualities
are required. The deeper tints improve glare control and provide a
higher degree of solar heat elimination.
The edges of all heat absorbing glass exposed to heat radiation
should be polished to reduce the possibility of thermal breakage.
The edges must be free of damage such as vents and chips.
Please request a Thermal Stress Evaluation for your project
before ordering, to identify the risk of any thermal cracking.
SolarVue™ provides medium solar control and a neutral, low
reflective appearance in a range of colours. A thin deposit of nickel
and chromium eliminates more than 55% of solar heat, while
transmitting more than 45% of visible light. SolarVue™ also
eliminates more than 99% of damaging UV radiation.
SolarVue™ is a PVB laminated safety glass marked to SABS
1263-1. SolarVue™ can be custom manufactured to meet various
safety, security and noise reduction standards.
Suggested applications:
Ÿ Medium solar energy control Ÿ Glare reduction in buildings Ÿ Glazed partitions and screens
Ÿ High Light (HL) Ÿ Extra High Light (XHL)
SolarVue™ is a sided product, meaning that its appearance will
vary when viewed from different sides. Care must be exercised
when cutting and glazing to ensure a uniform appearance. Stock
sheets are labelled by the factory to indicate the coated side.
SolarVue™ Neutral is best installed with the coating towards the
sun. Tinted SolarVue™ products are normally glazed with the
tinted side facing the sun. If optimum light and solar control are
required, the coated side should be placed outside
The visual appearance of coated glass is determined not only by
the colour of the glass and the coating. It is also influenced by
environmental factors such as the solar angle, ambient light level
and quality, reflections in the glass and the viewing angle. The
nature of coated glass makes it imperative to assess the true
colour and reflectance of the proposed product in the context of an
existing building, failing which in a full-scale mockup, before a final
selection is made. National Glass Distribution architectural
solutions specialists are available to assist with project
management and technical advice.

SolarShield makes it possible to create attractive buildings with
highly efficient solar control. The combination of a metallic coating
and a clear or tinted PVB (polyvinyl butyral) interlayer is designed
primarily to keep out as much of the sun's heat as possible. In
addition to reducing solar heat, SolarShield also limits the amount
of light entering the interior and blocks up to 99% of damaging UV
radiation. SolarShield is a laminated safety glass marked to i
SABS 1263-1.
It can be custom manufactured to meet various safety, security
and noise reduction standards. SolarShield is available in a range
of colours and three densities of coating. The numbers S10, S20,
S30 refer to the light transmission of the coating, which in turn is
directly proportional to the amount of solar heat entering the
building. For example, S10 indicates 10% light transmission on
coated glass prior to lamination.
Suggested applications:
Ÿ Maximum solar energy control Ÿ Curtain walls External solar screens Ÿ Skylights Ÿ Glare reduction in buildings Ÿ Glazed partitions and screens Ÿ One way vision panels Ÿ Reflective glass for wall cladding Ÿ Decorative safety mirrors Ÿ Lift interiors
SolarShield is a sided product, meaning that its appearance will

tinted side facing the sun. If optimum light and solar control are
required, the silver side should be placed outside. For one-way
vision, the tinted side must face the observer.

Acoustic laminated safety glass is manufactured with a special
vinyl interlayer that offers better sound control than traditional
polyvinyl butyral (PVB) interlayers. The sound control rating of
glass is expressed as a weighted sound reduction index (Rw)
measured in decibels (dB). Conventional laminated glass with a
single normal strength (NS) vinyl interlayer is rated at 33dB.
A high penetration resistant (HPR) interlayer can improve the
rating to 34dB. Acoustic laminated with a 0.76 mm HPR interlayer
is rated at 38dB and provides a noticeable improvement in sound
reduction. Acoustic laminates also work better at lower
temperatures because the Acoustic interlayer retains its sound
reducing properties better than traditional PVB interlayers. In
addition to a better weighted sound reduction index, Acoustic
laminates offer superior dampening across the coincidence dip –
a frequency range in which glass of a specific thickness typically
becomes more transparent to sound waves.
Acoustic laminates can be glazed into standard aluminium,
wooden or specialist frames to control noise from a variety of
sources, including aircraft, road traffic, music systems, public
events, schools and other busy institutions.
Acoustic laminates are available with any of the coloured vinyl
interlayers of the tinted laminated glass range. Acoustic laminates
can also be manufactured with any SolarVue™ or SolarShield
coated products.
Acoustic PVB Sound Transmission Loss
To put the table values in context, one must bear in mind that every
10dB difference in sound pressure level represents a halving or
doubling of the perceived noise. Therefore it can be assumed that
every db difference represents approximately 10%.
As 4mm float has an average STL of 29dB, it can be said that
6.76mm Acoustic Laminate is 7dB better i.e. 70%. 8.76mm
Acoustic Laminate would be 90% better than 4mm float.
It is important to remember that these acoustic values are very
dependent on the frequency of the noise source, and that low
frequency noise tends to be structure borne, and is extremely
difficult to insulate against. Examples of low frequency noise
would be jack hammers, exhaust brakes of trucks, bass music etc.
We also need to take into account that certain noise will come
through the actual frames of the doors and windows where they

Low Emissivity (Low E) coated monolithic glass offers superior
thermal insulation in standard frames designed for single glazing.
Low E products reduce heating and air-conditioning costs by
keeping more heat in during winter and blocking it out during
summer.
Low E is a clear glass that maximises light transmission, while
Solar E has a denser coating that controls solar heat radiation and
glare. Both Low E and Solar E are available in laminated and
toughened forms. For the ultimate in insulating performance, Low
E panels can be used in double glazed units.
The coated surface of the Low E Glass highlights finger marks and
general dirt. The surface may also highlight any scratches, which
would be invisible on a normal glass surface. Please contact
National Glass Distribution for cleaning and processing
instructions. Low E glass is a sided product, meaning that its
appearance may vary when viewed from different sides. Care
must be exercised when cutting and glazing to ensure a uniform
appearance. In single glazed applications, the coating must
always be to the inside of the building.

Environmental Influences
Bullet-resistant glass is a term for glass that is particularly
resistant to being penetrated when struck by bullets. Since
manufacturing glass of usable thickness capable of fully stopping
most bullets cannot currently be done, the industry generally
refers to it as bullet-resistant glass instead.
Bullet-resistant glass is usually constructed by using layers of
laminated glass. The desired result is a material with an
appearance and light-transmitting behaviour of standard glass but
offers varying degrees of protection.
Bullet-resistant glass constructed of laminated glass layers is built
from glass sheets bonded together with polyvinyl butyral. This
type of bullet-resistant glass has been in regular use on combat
vehicles since World War II.
The use of interlayers provides impact resistance, such as
physical assault with a hammer, an axe, etc. The interlayer
provides little in the way of bullet resistance.
The glass, which is much harder than the interlayer, flattens the
bullet and thereby prevents penetration. This type of bullet-
resistant glass is usually 28-78mm thick and is usually heavy.
Available in clear or textured versions, for vision or obscuration
respectively, readily available, and easy to handle, stock, cut and
glaze Georgian Wired Glass is suitable for use in fire and non-fire
applications.
Georgian Wired Cast (Obscure) and Georgian Wired Plate (Clear)
both have a 30 Min fire rating.
Should a safety glass application be required, we can laminate the
Georgian Wired Plate to a 3mm Clear resulting in a 9.76mm
Georgian Wired Plate laminated glass meeting the requirements
of SANS 1263 – 1
For a 2 hour fire rating, Pyran S borosilicate glass is available in a
6mm thickness. This can also be toughened for safety glass
applications.
It is vital to ensure that the framework also has the same fire rating
as the glass. Ceramic setting blocks and glazing tape is also
required to ensure that the glass does not fall out the frame.
Bear in mind that the Fire Rated Fenestration products will only
contain the fire within the designated area, and will not extinguish
the fire like a sprinkler system would.
Unlike sprinklers or other “active” protection systems, fire-rated
glass is on duty 24 hours a day. If there is a power failure, a loss of
water pressure, or a human error that interferes with the sprinklers
working properly, fire-rated glass will not be affected and will
continue to perform its function.
TOUGHENED SAFETY GLASS
Toughened safety glass is ideal for bolted structural glazing and
frameless applications. Superb resistance to thermal stress also
allows toughened safety glass to be used in applications such as
refrigerator and oven doors, where ordinary annealed glass would
be likely to fracture.
Toughened safety glass is available in a range of thicknesses and
various colours. Toughened safety glass meets the safety glass
requirements of the South African National Building Regulations.
Toughened safety glass is up to 5 times stronger than normal
monolithic float glass. National Glass Distribution also offers a service in which we will
do the deductions and design layouts of your frameless showers
once tight sizes are supplied. Frameless shower hardware is also
available, and please contact National Glass Distribution for
assistance.
Applications:
Ÿ All doors and sidelights, framed or unframed Ÿ Sliding or patio doors Ÿ Glazed panels in doors Ÿ Balcony enclosures Ÿ Shower doors and bath enclosures Ÿ Barriers between different levels Ÿ Low-level glazing Ÿ Balustrades Ÿ Hail resistance Ÿ Kitchen splashbacks Ÿ Where additional strength for wind loading is required Ÿ Where glass is subjected to high thermal stress Ÿ Table tops
Obscure patterned glass obscures a view without noticeable loss
of natural or artificial light. Obscure glass is available in a range of
textures, making it possible to achieve the desired functionality
with a decorative effect that complements the aesthetic
environment.
3 levels of privacy are available:
Ÿ A – Low obscurityŸ B – Medium obscurity Ÿ C – High obscurity

PRODUCT KNOWLEDGE
TOTAL SOLAR ENERGY (HEAT) ELIMINATION
This is a function of the Total Solar Energy (Heat) Transmission
performance figure referred to above.
For example, a Total Solar Energy (Heat) Transmission
performance figure of 41 will generate a Total Solar Energy (Heat)
Elimination performance figure of 59. Selection: The higher the
figure, the better the performance. SHADING COEFFICIENT (SC)
This figure is a function of the Total Solar Energy (Heat)
transmitted through the sample pane of glass as compared to the
Total Solar Energy (Heat) transmitted through a 3mm thick pane of
clear glass which has a shading co-efficient of 1.00.
For example, if the sample pane of glass has a shading coefficient
of 0.48, it means that the sample pane of glass allows the
transmission of 48% of the Total Solar Energy (Heat) that would be
transmitted through the 3mm thick pane of glass. Selection: The
lower the figure, the better the performance.
SOLAR HEAT GAIN COEFFICIENT (SHGC)
This is the total solar heat in the wavelength range between 300
and 2500 nanometres that is transmitted through the glass from
the exterior to the interior of the building. SHGC is a measure of
the direct heat transmittance plus the portion of solar heat that is
absorbed by the glass and is re-radiated into the interior of the
building.
The lower the SHGC, the better the solar heat elimination is
through the glass. U-VALUE
This figure indicates the amount of energy (measured in Watts)
that is lost through 1m² of the sample pane of glass for every
degree of temperature difference between the outside and the
inside ambient air. Selection: The lower the figure, the better the
performance. ULTRA VIOLET ELIMINATION
This is the amount of Ultra Violet either absorbed or reflected by
the glass.
For example, the UV Elimination on 6mm Clear Float would be ±
17% opposed to > 95% on the 6.38mm Clear PVB Laminated
Safety Glass. Selection: The higher the figure, the better the
performance.
ISO DAMAGED WEIGHTED TRANSMITTANCE (Tdw-ISO)
Tdw-ISO values illustrate the reduction in fading by taking both
Ultraviolet (UV) and visible light wave lengths into account.
IGDB
A listing of over 4000 glazing components with validated
performance specification from listed manufacturers.
SOUND REDUCTION (Rw)
A measure of sound insulation of glass based on an average value
measured in decibels (dB) taking into account the sound values,
frequencies and pitch sensitivity.
PRODUCT TERMINOLOGY
. VISIBLE LIGHT TRANSMISSION
This figure indicates the amount of light that passes through the
sample pane of glass.
For example, if the sample pane of glass has a Visible Light
Transmission performance figure of 32, it means that if the light
source is placed in front of the sample pane of glass, 32% of that
light will pass through that pane of glass. Visible light is measured
in the 380 to 780 nanometre wavelength range perpendicular to
the glass surface.
VISIBLE LIGHT REFLECTION
This figure indicates the amount of light that is reflected away from
the surface of the sample pane of glass.
For example, if the sample pane of glass has a Visible Light
Reflection performance figure of 9, it means that of the 100% of
light that strikes the surface of the glass, 9% is reflected back
towards the light source. As a guide, clear glass has a Visible Light
Reflection performance figure of 8. Selection: The lower the figure
the better. Consideration must be given to the effect of the light
reflected from the glass into the surrounding environment.
SOLAR ENERGY (HEAT)
Solar Energy (Heat) striking the surface of a pane of glass reacts
in three ways: a portion is transmitted through the glass, a portion
is reflected away from the glass surface and a portion is absorbed
within the glass.
DIRECT SOLAR ENERGY (HEAT) TRANSMISSION
This figure indicates the amount of Solar Energy (Heat) that is
transmitted directly through the sample pane of glass.
For example, if the sample pane of glass has a direct Solar Energy
(Heat) Transmission performance figure of 29, it means that of the
100% of solar energy (heat) that strikes the surface of the pane of
glass, 29% is transmitted directly through that pane of glass.
Selection: The lower the figure, the better the performance SOLAR ENERGY (HEAT) REFLECTANCE
This figure indicates the amount of Solar Energy (Heat) that is
reflected away from the surface of the sample pane of glass.
For example, if the glass has a Solar Energy (Heat) Reflectance
performance figure of 8, it means that of the 100% of Solar Energy
(Heat) striking the glass surface, 8% is reflected away from that
surface. TOTAL SOLAR ENERGY (HEAT) TRANSMISSION
The amount of Solar Energy (Heat) absorbed within the sample
pane of glass is re-radiated out through both surfaces of the glass
pane. This figure indicates the amount of Direct and Re-radiated
Solar Energy (Heat) that is transmitted through the sample pane of
glass.
For example, if the sample pane of glass has a Total Solar Energy
(Heat) Transmission performance figure of 41, it means that of the
100% of Solar Energy (Heat) that strikes the glass surface, 41% is
transmitted through the glass directly or through re-radiation.
Selection: The lower the figure, the better the performance.

NationalGlassDistributionlaminatedsafetyglassproducts
National Glass Distribution has listed numerous laminated
safety glass products which we manufacture on the South
African Glass Database (SAGDB). The Centre of Glass (CoG) performance specifications of
these products are verified by simulating the raw products,
which are listed on the International Glazing Database v48, in
LBNL software programs, Optics version 6 and Berkley Lab
Window v7.4.8. By having our products listed on the SAGDB, they can be
used in THERM Finite Element Simulator v7.4.3.0 to obtain
thermal performance figures, based on NFRC 100 – 2010
environmental conditions, of the complete fenestration
system combining glass, frame system and glazing
hardware. The complete fenestration simulation figures can be used for
your SANS 204 energy efficiency calculations instead of
having to use the SANS 204 Table 6 defaults.
Refer to www.natglass.co.za for our Centre of Glass (CoG)
pe r fo rmance va lues o f ou r g l ass p roduc t s o r
www.eaglealuminium.co.za for our simulated figures of our
complete aluminium range.NFRC

National Glass Distribution is affiliated with a number of associations that enforce a strict code of ethical conduct and adherence to the standards in the glass and aluminium industry.

Notes:
Ÿ Performance data calculated using LBNL So�ware by an AAAMSA accredited SAFIERA simulator using NFRC 100 – 2010 environmental condi�onsŸ These figures are based on Centre of Glass (CoG) values and exclude any framing componentsŸ Low E coa�ng is on surface 2 of the single glazed units and surface 3 of the double glazed units Ÿ Slight varia�ons may occur due to manufacturing tolerances
Safety and Security Ra�ngs:
Ÿ Normal Strength (NS) for human impact safety (1 x 0.38mm PVB Interlayer)
Ÿ High Penetra�on Resistant (HPR) for addi�onal security (2 x 0.38mm PVB Interlayers)
Ÿ High Impact (HI) for security in high-risk applica�ons (4 x 0.38mm PVB Interlayers)
Ra�ngs 1, 2 and 3 are compliant with SABS 1263 – 1 (Human Impact) and ra�ng 3 is compliant with SANS 1263 – 2 (Vandalism)

• Glass glazing materials shall comply with requirements of
parts 1 to 5 of SANS 50572
• Frames to receive glazing material shall comply with SANS
613 and be capable of withstanding the wind and impact loads
determined in accordance with the requirements of SANS
10400-B without deflecting more than 1/175 of their span
• The thickness of panes of glass, other than in lifts shall:
• The top and bottom of glass fins installed at butt joints of glass
panes shall be fully fixed to the supporting structure and have
overall dimensions as given in table 7. Silicone sealant that has
has a tensile strength of at least 1MPa shall be used.
REGULATIONS
AAAMSA VISUAL INSPECTION CRITERIA
In terms of SANS 10400-N any deviations from the above, for
example shaped fins, are to be approved by a duly appointed
Competent Person (Glazing) in writing for each individual contract/
GLASS FIN ASSEMBLY
NATIONAL BUILDING REGULATIONS
THE LAW
GLAZING INSTALLATIONS
(a) Be no less than that given in tables 1 to 4, or
(b) Be determined by a Competent Person (glazing) in
accordance with the requirements of SANS 10137, or
(c) Be based on wind loads determined in accordance
with the requirements of SANS 10400-B
NOTE: SANS 10400-B requires that wind loads be determined by a
Competent Person (structures). If no wind load is specified the
A butt joint is assumed to have no structural strength. Therefore panels which incorporate a butt joint are not
considered to be supported on all sides. A glass fin is necessary to
provide the support at the joint so that the pane can be considered
(a) Safely sustain any wind actions which can reasonably
be expected;
(b) Not allow penetration of water to the interior of the
building; and
(c) Be apparent, in the case of clear glazing, to any person

SIG UNITS
SANS 1414: SPECIFICATIONS OF SIG UNITS
Double Glazed Units (SIG) are manufactured from two or more
panes of glass held apart by a spacer and bonded with a hermetic
seal, trapping dehydrated air between the glass panes.
National Glass Distribution manufactures SIG's using black flexible
spacer bars and promotes Warm Edge, which contributes to
energy efficient fenestration products.
This flexible spacer follows the edge of the glass and is a complete
insulating glass spacer system which requires only one start and
finish joint. It limits heat loss transmission through the spacer bar.
Warm Edge Technology also performs better with regards to heat
loss through the unit.
(a) Position the breather tube (if supplied) to the top side of the jamb
(vertical) facing downwards. Crimp and seal the breather tube once
the unit is at its final installation
(b) Ensure that the framing system has sufficient weep holes/
drainage and that SIG’s are glazed with setting blocks wide
enough to support both panes of glass in accordance with
SANS 10137 (refer to Figure A pg 27)
(c) Neutral cure silicone is the only recommended sealant when
glazing SIG's. Consult with the sealant manufacture to ensure
compatibility of the products
(a) Controls heat and cold transfer through fenestration
(b) The reduction of sound transmission
(c) Increased wind-loading resistance
(d) Minimizing the formation of condensation on glass
(e) Increasing safety and security
(d) Flexible Warm Edge units are not suitable for flush or pressure
glazed applications
(e) Units with a high solar absorption may require a thermal stress
evaluation which is the responsibility of the installer
(f) Unless otherwise indicated, Low E coated glass will be glazed to
surface 3 of the SIG
(g) An SIG order form may be required on receipt of order if
information is missing
26
(a) The internal stresses created when glass is subjected to
variations in temperature across its area
(b) Edges are cooler than the centre of the glass and they expand
at different rates
(c) When the Safe Temperature Difference (STD) between the
centre and edge is exceeded (40°C for annealed and laminated),
the glass is under thermal stress and may crack
(d) Generally higher risk in solar control glasses – the higher the
solar absorption the higher the risk of thermal stress cracks
(e) Thermal breakage is generally recognised by the fact that it
starts perpendicular to the edge of the glass and results in a
'lazy' crack
(f) Damaged edges may cause cracking at a lower than
expected temperature differential
Refer to figure E (pg 27) for thermal stress illustrations
• What is Thermal Stress?
THERMAL STRESS
It is the responsibility of the persons installing the glass to ensure
that it does not crack due to thermal or other causes. The installer
should request a thermal stress evaluation by the glass manufacturer
or Competent Person (Cat 1) to protect the interests of all parties
concerned before commencement of the project.

ThermalStressAnalysisrequested?
This indicates if the glass will crack due to the thermal differences between the glass and frame. Na�onal Glass can provide this for your installer.
Willtheunitkeepheatinorout?
It’s important to understand what you want the glass to achieve. For warmer climates one should focus on the SHGC value. If you reside in a colder climate, the U-value is important.
Correctsettingblocksused?
Se�ng blocks are used to install glass in the frame. If the incorrect blocks are used, there is a chance the glass will break.
Breathertubeontheunit?
A breather tube is inserted into the glass, to allow the glass to expand and contract if moving between different al�tudes. Once the glass is installed the breather tube will need to be crimped by the installer to avoid condensa�on build up in the unit.
The type of spacers used in double glazing is important, as some may transfer energy and require mul�ple joints (poten�al for leaks). Na�onal Glass Distribu�on units are made using fl e x i b l e , n o n - c o n d u c � v e , “ Wa r m E d g e Technology” spacers. These perform be�er than aluminium spacers with regards to heat loss and the flexible spacer follows the full perimeter of the glass, thus requiring only one joint.
In South Africa where we have a warmer climate,
Na�onal Glass Distribu�on recommends the following cost effec�ve double glazing make up Solarvue Neutral – 12mm Air Gap – NG PVB Clear.
Where glass with a higher solar absorp�on factor is specified, it is recommended that a thermal stress analysis is carried out to avoid thermal stress cracks. These can occur when the centre of the glass becomes ho�er than the edges.
A glazing cer�ficate should be requested from the installer to ensure that the installa�on complies with the SANS 10400-N (Glazing) standard, which means that the correct glass thickness has been used and that safety glass has been used where required.
Na�onal Glass Distribu�on proudly carries the SANS 1263-1 mark on all of its safety glass and conforms to SANS 613 with its Eagle Aluminium product range.

ENERGYEFFICIENTPRODUCTS
WHATTOLOOKFORIN
Choosing the correct performance glass is a vital aspect of any building as it has a considerable impact on quality of life within the home. A more comfortab le and energy efficient l i v ing environment can be achieved when glazed elements are implemented in accordance with SANS 10400 XA (Energy Usage) and SANS 204 (Energy Efficiency in Buildings) standards.
Key to understanding energy efficiency is knowing what U-Values and Solar Heat Gain are. Glass and glazed products are rated according to these and assigned values.
U-Value is a unit of measurement describing the ability of any given building element such as a window, wall, or roof to transfer heat. The lower the number, the be�er the insula�on; ie. less heat is being lost to the outside. The higher the number, the more energy is being transferred and the higher the costs of hea�ng/cooling the building.
Solar Heat Gain Coefficient is usually referred to as SHGC. This measures the glass' ability to transmit solar energy into a room. The higher the value, the greater its ability to transmit solar heat. Depending on circumstances such as eleva�on, al�tude, la�tude and geographical loca�on (bo�om of a cold valley or up on a sun soaked hill), the requirement for higher or lower SHGC should be carefully considered.
Heat escapes through glass, so energy efficiencies can be substan�ally improved by using glass that offers be�er insula�on than plain monolithic (single layer) clear glass. To reduce heat loss through glazed elements, a Low E (low emissivity) glass or double glazing unit is recommended.
Benefits of double glazing:
· Improved sound reduc�on
· Improved security
· Improved resistance to wind-loads
· Improved thermal insula�on
· Improved solar energy control
· Minimized condensa�on

SCRATCHES AND BLEMISHES
EXTRACT FROM AAAMSA SELECTION GUIDELINES 2012 - CHAPTER 10.4.4
Ÿ The scratch and blemish inspection should be viewed at a
distance of 3 metres under normal lighting conditionsŸ Normal lighting conditions shall mean reasonable lighting
conditions under which the product is normally viewedŸ If visible when viewed from a distance of 3 metres under the
lighting conditions described, the product/s may be rejected
GLASS INSPECTION
Ÿ Scratches in glass which are applicable, are those which are
under 75mm long in any area, and those which are longer
than 75mm which do not encroach more than 75mm from
the edge
GLASS DISTORTION/COLOUR VARIATIONS
Ÿ There will always be some degree of distortion in glass
Ÿ Toughened glass has more distortion than annealed glass
Ÿ Some gasket glazed systems such as roll-in or wedged
gaskets tend to create more distortion than other systemsŸ SIG units will distort due to changes in temperature and
atmospheric pressureŸ SIG units feature a spacer between the two sheets of glass
round the perimeter of the unitŸ This spacer is set in the from the edge to allow for the
inclusion of a secondary sealŸ The spacer is often visible and the rebate and primary seal,
being soft mastic; is not always perfectly flush with the
spacer inner surface. In addition both the spacer and the
sealant may protrude beyond the sight line and, provided
the requirements of section 10.4.4 are met, this is
considered acceptableŸ Colour, reflectance and transmission in functional glasses
may vary slightly and is considered acceptable

DEFINITIONS
Toughening is the process whereby float glass is processed to
increase its strength, making it a safety glass.
Toughened glass is also referred to as Tempered glass.
PRODUCT KNOWLEDGE
Ÿ Toughened glass must be cut to size and the edge work
processed before toughening, and cannot be re-worked
once toughenedŸ Polishing the edges or drilling holes in the glass must also
be carried out before the toughening process startsŸ Toughened glass breaks into small chunks instead of
splintering into jagged shards. The small chunks are less
likely to cause injuryŸ As a result of its safety and strength, toughened glass is
used in a variety of demanding applications, including: Showers Balustrades Frameless glass doors Table tops Doors and windows
Ÿ PROCEDURE FOR GLASS TO BE TOUGHENED Ÿ CuttingŸ Processing (refer to table)Ÿ Toughening
Ÿ GLASS WHICH CANNOT BE TOUGHENED Ÿ LaminatedŸ Bullet ResistantŸ Glass which is too small (1 side must be 300mm)Ÿ Glass which is too long and narrow i.e. 1:16 glass ratioŸ ChippedŸ Heavily patterned obscureŸ Georgian WiredŸ Glass with no edge work
Ÿ IMPORTANT CONSIDERATIONS
Washing:
Ÿ The glass has to be washed and dried before the
toughening processŸ Glass has to be washed immediately after cutting, grinding
or drilling to avoid the glass staining
Storage:
Ÿ Float glass must be stored indoors and in a clean, dry and
warm place to avoid moisture and dirt on the glass surfaceŸ The humidity must be less than 80% and the temperature
must be over 10°CŸ Moisture causes staining, and other problems on the glass
surface, which will cause irreparable damage

COATED GLAZING INSTALLATION GUIDE
SOLARSHIELD / SOLARVUE LAMINATED SAFETY GLASS
The coating is applied to surface 3. Therefore the coated side
sticker will be applied to surface 1, and hence the coated side is
glazed to the outside. The tinted colour is always glazed to the
outside.
LOW E MONOLITHIC AND LAMINATED SAFETY GLASS
The coated side of Laminated Low E product should never be
on surface 2 or 3, as this affects the performance of the Low E
coating. The Low E coating should be on surface 2 for
Monolithic Glass and on surface 4 for Laminated Safety Glass,
and hence the coated side should always be glazed to the
inside.
Monolithic glass has 2 surfaces:Ÿ surface 1 being the external surface and;Ÿ surface 2 the internal surface Ÿ i.e. surface 1 is glazed to the outside
Laminated Safety Glass has 4 surfaces:Ÿ surface 1 being the external surfaceŸ surface 2 and 3 are facing the vinyl and;Ÿ surface 4 being the internal surfaceŸ i.e. surface 1 is glazed to the outside

1. STORAGE & TRANSPORT
Ÿ Store mirrors vertically. Do not lay mirrors flat. Glass
exhibits more strength when stored upright.
Ÿ Make sure that the handling equipment used is strong
enough to handle the weight of the mirror. A dropped
mirror is a ruined mirror.
Ÿ Ensure that the area where the mirror is stored, is dry -
avoid condensation.
2. PROCESSING & CUTTING
Ÿ Make sure that mirrors (especially backs and edges)
are thoroughly washed after manufacture - use clean
water to wash.
Ÿ Replace water in polisher and/or beveller regularly.
The water PH level is recommended to be between
6.5 and 8.0 (close to neutral).
Ÿ PFG highly recommend using a water based varnish
to seal all processed glass.
Ÿ Run the processing machine empty before taking a
break or shutting for the day to prevent mirror standing
in water longer than necessary.
Ÿ When cutting the mirror, try to keep at least one factory
edge, and install this edge at the bottom where
puddling may occur.
Ÿ Always grind or polish as shown, to minimise chipping
and damage to the protective paint layer.
3. FIXING & INSTALLATION
Ÿ Use gloves when handling a mirror to prevent skin-
borne salts or chemicals from damaging the mirror
face or backing.
Ÿ Wear the correct safety equipment.
Ÿ Paint the wall behind the mirror only with enamel paint
and allow the paint to dry.
Ÿ Set the mirror at least 5mm off the wall, allow air to
circulate behind the mirror - don’t seal the mirror into
the recess. Recommended in EN 1036.
Ÿ Use a water based varnish to seal the edges in any
area of high humidity - bathrooms and gyms.
Ÿ Use adhesive that is specifically recommended for
mirrors. Apply the adhesive in vertical strips.
Ÿ Use approved tapes, mastics and adhesives. Ask your
adhesive supplier for recommendations.
THIS WAY UP
DO
DO
Ÿ Use neutral cure silicons and tapes recommended for
use on mirrors. PFG recommends caution using any
silicon in contact with mirror.
Ÿ Use grommets on screws to protect metal screw
contact on glass.
Ÿ Follow the adhesive manufacturer recommendations
Ÿ Ensure the area is well ventilated and free of fumes or
solvents, typically from grout cleaners, tile adhesives
or similar.
Ÿ If adhesive is used, be sure it is approved for mirror
use.Ÿ Never use an abrasive cleaner on any mirror surface.
Ÿ Mechanical fastening devices should always be used
in conjunction with the adhesive - this helps prevent
possible personal injury or damage if the adhesive
fails.Ÿ Remove surface marks or dirt with an oil-free cloth.
Ÿ A frame is recommended for longevity.
Ÿ Ensure the correct product with sufficient tactile and
adhesive strength is used as recommended by the
adhesive supplier.
4. MAINTENANCE
Ÿ Clean the mirror regularly by washing it with a soft
cloth, rinsing it with warm water and drying it with a soft
cloth.
Ÿ When using a window cleaner, spray the liquid on the
cloth first, and then wipe the mirror. Keep the edges dry
at all times.
Ÿ Install mirrors on new plaster, new masonry or on a
freshly painted wall.
Ÿ Use silicon with algaecide or that says “mold resistant”.
Ÿ Use acid based glues: only natural cure adhesives.
Ÿ Install mirrors outdoors, without additional engineered
protection for the backing and the edges of the mirror.
Ÿ Use any acid or alkali cleaners on mirrors. Chemicals
attack the surface, edges and backing of the mirror.
Ÿ Install on uneven surfaces. This can cause stress or
strain on the mirror, which can cause the surface or
backing to crack. It can also cause the mirror to warp,
leading to distortion.
Ÿ Slide one mirror sheet over another, as this will scratch
the mirror surface.

CLEANING GUIDELINES FOR LOW E HARD COATED GLASS
1. ROUTINE HAND CLEANING
This procedure should be followed as
required, to remove accumulated dust and
fingerprints.
Recommended Cleaning Products:
Ÿ Clean lukewarm soapy water
Ÿ Solution of one part vinegar to ten parts
clean waterŸ Commercially available vinegar based
cleanersŸ Commercial domestic glass cleaners
such as Mr Muscle Window and Surface
CleanerŸ Clean lint-free soft cloth
Recommended Cleaning Procedure:
Ÿ Always start cleaning at the top of the
window or door and work down.Ÿ Flush with generous amounts of clean
water to remove dirt particlesŸ Spray with soapy water (and/or vinegar
solution for more stubborn marks).Ÿ Remove all traces of cleaning solution
by rinsing with clean water. Excess
water must be removed with a cloth.Ÿ To prevent streaking, do not dry
completely but leave a think film of
moisture on glass. This film will quickly
evaporate, leaving a clean surface.Ÿ Repeat the process if necessary.
Ÿ Do not wipe with a dry cloth, or when the
surface is dry.
DON’T
Low E glass is an energy efficient product that has a very thin coating applied to one surface during its manufacture. National Glass
Distribution only supplies “hard coated” Low E glass, i.e. the coating is what is referred to as a pyrolytic coating.This is a thin coating which is
chemically bonded to the glass surface while it is still in a semi-molten state, which reacts to form a hard, durable ceramic coating. This
coating provides improved control of thermal insulation over ordinary float glass.
The coated surface, always glazed to the inside of the building (except in Insulated Glass Units where it is on the inner pane but facing
outside), requires a slightly different cleaning procedure to that needed for ordinary, uncoated float glass.
The following recommended guidelines provide the best results when cleaning the coated surface. Any preferred cleaning method for float
glass in acceptable for the uncoated surface.
Precautions & Warnings
Ÿ Use abrasive, powder-based, ammonia-based or alcohol-based cleaning solutions.
Ÿ Use cleaners that contain any harsh acid or alkali (hydrochloric acid is the exception to this, under certain circumstances only, and is
covered under “Specialized Cleaning” further down).Ÿ Clean glass when it is hot, or in direct sun light.
Ÿ Use hot water on cold glass, or cold water on hot glass.
Ÿ Use power washers or garden hoses to clean windows and doors
Ÿ Allow cleaning solutions to contact the edges of any laminated glass.
Ÿ Allow cleaning fluid to dry on glass, or surrounding surfaces.
Ÿ Use squeegees, razor blades, scrapers, scourers and metal or abrasive products.
3. SPECIALIZED CLEANING
The Low E coating is hard enough that any
metal object coming in contact with it, may
lose a tiny amount of metal, which may be
deposited on the coated surface. This may
appear as a “stain” or “scratch”.
Recommended Cleaning Products:
Ÿ Solution of 10% Dilute Hydrochloric
Acid (such as typical pool acid) to 90%
clean waterŸ Clean lint-free soft cloth
Recommended Cleaning Procedure:
Ÿ Observe all handling, safety and
disposal instructions of the chemical
manufacturer.Ÿ Wear protective gloves and eye wear,
and take extreme care not to spill any
acid or solution. The diluted solution
may be corrosive to any organic matter.Ÿ ALWAYS ADD ACID TO WATER Adding water to the acid could cause it to
react violently and splutter, causing
injury or dame. Pour the water into the
container first, carefully stir the acid into
the water, in the proportions indicated.Ÿ Apply a small amount of the prepared
solution to a clean WET cloth.Ÿ Rub gently, only on the area requiring
spot cleaning, taking care not to allow
the cleaner to come into contact with
any surrounding frame, surface or
paintwork.Ÿ Wipe clean with a wet cloth.
Ÿ Follow this with the recommended hand
cleaning procedure.Ÿ Do not wipe with a dry cloth, or when the
surface is dry.
2. SPOT CLEANING
This refers to individual spots or areas of
stubborn dirt and foreign materials, such as
grease, oil, tape adhesive, paint and even
crayons.
Recommended Cleaning Products:
Ÿ Acetone
Ÿ Denatured alcohol
Ÿ Mineral turpentine
Ÿ Clean lint-free soft cloth
Recommended Cleaning Procedure:
Ÿ Observe all handling, safety and
disposal instructions of the chemical
manufacturer.Ÿ Apply a small amount of the cleaner to a
clean WET cloth.Ÿ Rub gently on the area requiring spot
cleaning, taking care not to allow the
cleaner to come in contact with any
surrounding frame, surface or paintwork
which may be damaged or marked by
these solvents.Ÿ Wipe clean with a wet cloth.
Ÿ Follow this with the recommended hand
cleaning procedure.Ÿ Do not wipe with a dry cloth, or when the
surface is dry.

TECHNICAL
PUTTY GLAZING GUIDELINES
Ÿ Ensure that the frame is clean and dry and that all rust is
removed in the case of steel windows.
Ÿ Metal frames should be painted with a primer.
Ÿ Wooden windows must be sealed with a suitable wood sealer.
Ÿ Ensure that all applications are left to dry according to
manufacturer's specifications.
Ÿ Do not add any chemicals such as turpentine or paraffin to the
putty, as this prevents it from hardening and may cause
cracking.
Ÿ Putty glazing without beads will require approximately 2kg per
m² of glass.
Ÿ Pen the bag of Putty and knead it until you get a uniform
consistency.
Ÿ Mix the putty with the supplied catalyst.
Ÿ Thoroughly knead the putty, ensuring that the catalyst is
properly mixed.
Ÿ For back putty, do not add the catalyst, as the glass expands
and contracts with heat and needs space to move.
Ÿ Back putty should be evenly applied 3mm thick by hand.
Ÿ Apply pressure only at the edges of the glass when inserting
the pane into position.
Ÿ The front holding putty should be applied with a putty knife and
at angle of 60°.
Ÿ Allow 7 – 10 days for putty to dry, before it is painted.
Ÿ The glazed putty should not be left unpainted for a period of
longer than 17 days to prevent cracking.
