Glass makes for effective prevention from impact and brute contact.
Armor Glass
Armor Glass brings the benefits of strength and safety to any application and is an ideal
recourse for the building and construction industry. The formidable strength of Armor
Glass makes for effective prevention from impact and brute contact.
Armor Glass is a laminated glass, regarded as a safety glass, consisting of two or more panes
of glass with one or more layers of polyvinyl butyral (PVB) sandwiched between them and
treated. The glass panes can be basic float glass or tempered or heat strengthened panel. If
the glass is broken fragments tend to adhere to the PVB interlayer thereby reducing the risk of
injury from falling glass and helping to resist further impact or weather damage. PVB
membrane has good tenacity performance and when the laminated glass breaks due to
violent force, the PVB will absorb large amount of impact energy and disperse it rapidly.
Therefore, it hard to break the laminated glass and the shape of the glass may be maintained
even if being broken. Furthermore, personnel inside and outside the buildings will not be hurt
by the glass fragment.
Safety Application
Safety glazing applications, such as doors and sloped overheads, require a minimum
.030" (.76 mm) thick PVB interlayer. Clear PVB plies can be added to achieve the minimum
.030" (.76 mm) thickness required in safety glazing areas.
Solar Control Application
The glass also possesses other unique properties, which make it an excellent product for
commercial buildings. For instance, laminated glass provides the greatest reduction of
ultraviolet (UV) light transmission of any commercial glass product available.
When combined with two layers of float glass, less than one percent of UV light is
transmitted. This is important when considering the type of glass product to use in
applications where UV protection is essential. However, light and heat can also contribute
to the fading of interior furnishings.
It is important to consider using laminated glass products, which help to reduce visible
light transmission and radiant heat.
Sound Control Application
Another important element of laminated glass is acoustical performance in commercial
applications. Laminated glass reduces noise transmission due to sound damping
characteristics of the PVB interlayer.
While glass is inherently a poor acoustical performer, higher performance levels can be
achieved by using laminated glass alone or combined with additional glass plies to form a
sealed insulating glass unit.
Protective Glazing Applications
Security - For many years laminated glass has been used in low-to-medium level security
applications.
Windborne Debris - The glass protects building interiors from the winds and rain
associated with hurricanes. Armor glass is a durable, high-performance glazing that
provides glass retention in the opening if the glass is broken due to the impact of flying debris.
Bomb Blasts - Armor glass offers protection when a building is exposed to the threat of
explosives. Tests have shown that when windows glazed with laminated glass are subjected
to a blast impulse, broken glass fragments tend to adhere to the plastic interlayer rather than
spraying building occupants with harmful glass shards or other debris.

FIELD SALES REPRESENTATIVES
We're here to help with design assistance, budget costing, return on investment costing,
spec writing and review as well as act as a liaison between architects and glazing
contractors. We also work closely with the glazing contractor to offer assistance with initial
costs, final pricing negotiations, product information and job site inspections. Just ask.
Color Rendering Index (CRI)
The ability of transmitted daylight through the glazing to portray a variety of colors
compared to those seen under daylight without the glazing. Scale is 1 - 100. For instance,
a low CRI causes colors to appear washed out, while a high CRI causes colors to appear
vibrant and natural. In commercial glass, CRI indicates the effect the specific glass
configuration has on the appearance of objects viewed through the glass. Heat gain is
heat added to a building interior by radiation, convection or conduction.
Heat Transfer Methods
Heat transfer occurs through convection, conduction or radiation (also referred to as
"emission"). Convection results from the movement of air due to temperature differences.
For instance, warm air moves in an upward direction and, conversely, cool air moves in a
downward direction. Conduction results when energy moves from one object to another.
Radiation, or emission, occurs when heat (energy) can move through space to an object
and then is transmitted, reflected or absorbed.
Light to Solar Gain
Ratio of the visible light transmittance to the Solar Heat Gain Coefficient. A higher LSG
ratio means sunlight entering the room is more efficient for daylighting, especially for
summer conditions where more light is desired with less solar gain. This ratio is the
measurement used to determine whether the glazing is "spectrally selective."
Low-E Coatings
Relatively neutral in appearance, low-E coatings reduce heat gain or loss by reflecting
longwave infrared energy (heat) and, therefore decrease the U-Value and improve energy
efficiency. Current sputter-coated low-E coatings are multilayered, complex designs
engineered to provide high visible light transmission, low visible light reflection and
reduce heat transfer.

Glossary
Relative Heat Gain (RHG)
The total heat gain through glass for a specific set of conditions. This value considers
indoor/outdoor air temperature differences and the effect of solar radiation.
R-Value
A measure of the resistance of the glazing to heat flow. It is determined by dividing the U-
Value into 1. A higher R-Value indicates better insulating properties of the glazing. R-Value
is not typically used as a measurement for glazing products and is referenced here to
help understand U-Value.
Shading Coefficient (SC)
An alternative measure of the heats gain through glass from solar radiation. Specifically,
the shading coefficient is the ratio between the solar heat gain for a particular type of
glass and that of double strength clear glass. A lower shading coefficient indicates lower
solar heat gain.
Solar Energy
Radiant energy from the sun having a wavelength range of 300 to 4000 nm, which
includes UV (300 to 380 nm), visible light (380 to780 nm) and near infrared energy (780 to
4000 nm).
% Reflectance Out - percentage of incident solar energy directly reflected from the glass
back outdoors.
% Absorptance - percentage of incident solar energy absorbed into the glass.
% Transmittance - percentage of incident solar energy directly transmitted through the
glass.
The sum of percent reflectance out + absorptance out + transmittance = 100%. An
additional consideration is emission, or emissivity. This refers to the reradiation of
absorbed energy that can be emitted toward both the exterior and interior of the building.
Emissivity is controlled through the use of low-emissivity, or low-E coatings.
Solar Heat Gain Coefficient (SHGC)
The percent of solar energy incident on the glass that is transferred indoors, both directly
and indirectly through the glass. The direct gain portion equals the solar energy
transmittance, while the indirect is the fraction of solar incident on the glass that is
absorbed and re-radiatedor convected indoors.
Solar/Reflective Coatings
Typically, highly reflective coatings that reduce solar heat gain through reflection and
absorption. Though very effective at reducing heat gain, visible light transmittance is
generally low and U-Values are not as energy efficient as low-E coatings.
Transmittance Percent
Percentage of incident ultraviolet energy that is directly transmitted through the glass.
Long-termexposure to UV light may result in fabric and pigment fading, plastic
deterioration and changes to the appearance of many types of wood.
UV
Ultraviolet radiant energy from the sun having a wavelength range of 300 to 380 nm with
airmass of 1.5.
U-Value (U-Factor)
A measure of the heat gain or loss through glass due to the difference between indoor &
outdoor air temperatures. It is also referred to as the overall coefficient of heat transfer. A
lower U-Value indicates better insulating properties. The units are Btu/(hr)(ft2)(°F).
Relative Heat Gain (RHG)
The total heat gain through glass for a specific set of conditions. This value considers
indoor/outdoor air temperature differences and the effect of solar radiation.

Value into 1. A higher R-Value indicates better insulating properties of the glazing. R-Value
