BULLET
RESISTANT GLASS
Bullet
resistant glass is created by using multiple layers of glass with multiple
layers of laminate. Bullet resistant glass can be fabricated in many different
configurations. The most popular are as follows:
CLASS I - .38 Special
Handgun
4 Lites of 1/4" + 1 Lite of 1/8" = 1
3/16"
CLASS II - .357 Magnum
Handgun
1 Lite of 1/4" + 1 Lite of 3/8" + 2 Lites
of 1/4" + 1 Lite of 1/8" = 1 1/2"
CLASS III - .44
Handgun
1 Lite of 1/4" + 2 Lites of 3/4" + 2
Lites of 1/4" + 1 Lite of 1/8" = 1 3/4"
CLASS IV - High Power
Rifle
8 Lites of 1/4" + 1 Lite of 1/8" Heat
Strengthened = 2 1/2"
SECURITY
GLASS
Security
has become a growing concern to the business community. Laminated glass provides
safety as well as security. Tempered glass can easily be broken with one smack
from a sharp object. By installing tempered glass laminated to annealed glass,
the glass may smash, but will not come crashing to the floor. Multiple layers
can be added, including bullet resistant glass for the protection of people as
well as property.
Security glass can be offered in many
different configurations. An example is using tempered glass as an outboard lite
for impact strength with annealed inboard lite for holding the window in place
after it is broken. Various materials can be placed in the interlayer for added
security, such as Wire Mesh, Kevlar, expanded metal, and
others.
SOUND CONTROL
Noise
pollution is a problem more people are facing in already crowded cities.
Laminated glass provides unique sound control properties. STC ratings are given
to glass with the higher STC number being the best. Sound waves are interrupted
when passing through laminated glass. By varying the thickness of the glass used
in the sandwich, higher STC ratings are reached.
Multiple layers (3 or 4) further quiet
the interior environment. Insulated glass made with laminated glass on both the
inboard and outboard lites will achieve the highest
rating.
Air spaces and some gasses contained in
an air space will also increase the STC rating.
U. V. CONTROL
By using
a glass laminate, you are automatically providing a filter with every lite
of glass. The glass laminate stops 99% of damaging ultraviolet rays, thus
preventing fading of carpets, wall coverings, drapes and furniture, as well
as any health related problems.
