Glass and framing must undergo extensive testing in an independent laboratory before receiving a fire-rating. View brief video clips of the tests below.
To earn a fire rating, glass must pass rigorous tests conducted by an independent laboratory. Glass, framing and door components are heated in a furnace to simulate the high temperatures of a building fire. The lab assigns the products a fire rating of 20 minutes to 3 hours, depending on how long they resist breakage. Technical Glass Product's FireLite® glass ceramic, Pilkington Pyrostop® transparent wall panels and other fire-rated products are UL-listed and are suitable for blocking the spread of flames and smoke.
Hose Stream Test
The hose stream test is the second part of the testing requirements for fire-rated glass. It is required in the U.S. for all fire ratings over 45 minutes, and in Canada for all fire ratings. Immediately following heating in a furnace, hot glass is sprayed with water from a fire hose at specified pressures. The cooling, impact and erosion created by the hose stream tests the integrity of the glass and eliminates inadequate materials. Products from Technical Glass Products with fire ratings greater than 20 minutes such as FireLite® and Pilkington Pyrostop® have all passed the hose stream test.
Where intended for use in doors, sidelites, walls or other areas where people or objects may run into it, fire-rated glazing is subjected to an impact test. The test determines the amount of force it can resist by dropping a bag of lead shot against a vertical piece of glass from various heights. Technical Glass Products offers several fire-rated and impact safety-rated products, including FireLite Plus® and FireLite® NT glass ceramic and Pilkington Pyrostop® transparent wall panels.
