Page Background


Glass, framing and components are heated

in a furnace during the fire test to simulate

the high temperatures of a building fire. The

testing lab assigns the products a fire rating

of 20 minutes to 3 hours, depending on how

long they remain in the wall with no flaming

on the exposed surface of the assembly.

Hose Stream Tested

Immediately following the fire test, heated glass is

subjected to water from a fire hose. The cooling,

impact and erosion created by the hose stream tests

the integrity of the glass. This test is mandatory

for products with fire-ratings over 20 minutes in

the U.S. (and in Canada for all fire ratings).

Positive Pressure

Once the fire reaches equilibrium in the positive

pressure zone, smoke, hot gases and flames

are forced through any openings in the door or

window assembly. Testing to the UL 10C standard

more closely simulates real fire conditions.

Heat Barrier

Blocks radiant and conductive heat transfer from

one side of the glass to the other. A required

characteristic of glass used as a wall.


Building codes clearly define hazardous locations

where impact safety glass is required. Glass with

this designation has to be tested to meet impact

safety requirements required for areas such as

doors, sidelights, and areas close to the floor.

Stainless Steel (option)

Available with stainless steel frame finish

options for increased design flexibility.

Hurricane-Rated (option)

Meets stringent hurricane requirements

with relative Florida Product Approvals.

Energy Efficient

Designed for use in exterior applications

where energy codes require an insulated

product, or for interior applications with

special needs such as sound reduction.

Bullet Resistant (option)

The ability of the glass to stop various types

of ammunition. Ratings are assigned in levels

from 1 to 8, with a Level 8 rating being the

highest (able to stop a 7.62 mm rifle lead

core full metal copper jacket, military ball).

Load Bearing

The capacity of an element in a building

structure to support a weight in addition

to its own.

UL Classified and Labeled

Classified and labeled by Underwriters

Laboratories, Inc.®(UL), an independent

product safety certification organization.
