Laminated Glass:
Laminated glass, often called "safety glass", consist of two lites
of equal thickness bonded together with a plastic interlayer, or
polyvinyl butyral (P.V.B.). In the event that the glass should
break, the P.V.B. interlayer in most cases will allow the glass to remain in the
framing. Colored PVB's which allow a virtually unlimited
range of color can be incorporated into most projects.
Insulated Glass:
Insulated glass consists of a 1/4" thick outer lite, over a 1/2"
air space, over a laminated inner lite. Insulated glass is used
in skylights and sloped glazing over a conditioned space. When
energy efficiency is of paramount concern.
Annealed Glass:
Annealed glass is the state in which float glass becomes after
it is poured from a molten state into a bed of molten tin.
This glass is allowed to solidify, and then is cooled under
controlled conditions which turns the glass into an annealed
state. Most glazing codes prevent this type of glass from
being used in hazardous
locations.
Tempered
Glass:
Tempered glass is produced by heating annealed glass to
approximately 1150 degree F, then cooling the glass rapidly
by blowing air on both surfaces of the glass simultaneously.
Tempered glass is about four times as strong as annealed
glass of the same size and thickness. When tempered glass is
broken, it breaks into very small pieces. One problem that
exists with tempered glass is spontaneous breakage; the
glass will break for no apparent reason. Spontaneous
breakage occurs when nickel sulfide stones increase in size
due to repeated heating and cooling.
Heat
Strengthened Glass:
The heat strengthened glass process is similar to that of
tempered glass. The annealed glass is heated to
approximately 1100 degrees F, but the cooling process is
slower than that for tempered glass. Heat strengthened
glass is about twice as strong as annealed glass of the
same size and thickness. One of the benefits of heat
strengthened glass is that it is far less susceptible to
spontaneous breakage. Due to this, we recommend to use of
heat strengthened glass for skylights.
Low-E
Coated Glass:
Low-E coatings are metallic-oxide coatings that are
applied to the interior surface of the glass, which is
invisible to the naked eye. Low-E coatings reflect the
"long" infrared (IR) portion of sunlight, which is the
radiant heat portion. Depending upon which surface of
the glass on to which it is applied, it can keep radiant
heat from entering, or escaping a building. There are
two types of Low-E coatings, Pyrolitic or Sputter coat.
In Pyrolitic coatings the metallic-oxide coating is
applied directly to the hot glass. Sputter coat Low-E
coatings are applied through the use of a vacuum chamber
filled with gas, to which an electrical charge is
induced. Due to the application process, Sputter
coatings offer better performance numbers, and can be
applied to tinted glass.
Reflective Coated Glass:
Reflective coatings are similar to that of low-E
coatings, except that it has a "mirror" like
appearance. Also, reflective coatings have a low
shading coefficient and visible light transmittance.
Tinted
Glass:
Tinted glass is used to reduce the amount of direct
sunlight and glare that enters a building. Tinted
glass is available in many different colors; green,
grey, bronze and blue-green are standard colors
which are most readily available. Premium colors
included blue, Evergreen and Azurlite.
Ceramic Frit Coated Glass:
Ceramic frits are often applied to glass to
produce architectural enhancing features to
skylights. Ceramic frits can help to reduce glare,
and decrease solar transmission. The ceramic
material is silkscreened on to the glass, and then
is heat fired to the glass. The patterns can range
from a simple dot pattern to a one of a kind
custom pattern. The frits are also available in a
wide range of colors. Please note that the maximum
lite size of most frit patterns is 60" x 120".
Fire -Rated Glass Ceramic:
FireLite is a 3/16" (5mm) thick fire-rated glazing
material. It is listed for use in non-impact
safety-rated locations such as
transoms and
borrowed lites with fire rating requirements
ranging from 20 to 90 minutes.
Clear Wire Glass:
For Fire rated
windows,doors and sidelites with a fire rating of
up to 45 minutes. Diamond and Square patterns
available.
Patterned Glass:
A wide range of different patterns to meet your
decorating ideas.

Bullet Resistant Glass:
Bullet resistant security glass, storefronts
and transaction counter systems. Bullet resistant
levels range from I thru VIII as well as hurricane
impact systems.
