This additional time is intended to allow for the enactment of lock-down protocols and to allow for the arrival of emergency response teams. Glazing designed to increase the amount of time required to gain entry. Listed and labeled by Intertek, an independent assurance, testing, inspection and certification organization. The capacity of an element in a building structure to support a weight in addition to its own.

Ratings are assigned in levels from 1 to 8, with a Level 8 rating being the highest (able to stop a 7.62mm rifle lead core full metal copper jacket, military ball). The ability of the glass to stop various types of ammunition. The ability of glass ceramic to withstand sudden heating, cooling, or both without cracking, shattering or exploding out of the frame. Withstands continuous temperatures to 1292° F for use in high efficiency heating appliances. It is designed for use in exterior applications where energy codes require an insulated product, or for interior applications with special needs such as sound reduction. Glass with this designation has been tested to meet impact safety requirements required for areas such as doors, sidelights, and areas close to the floor.įireLite IGU is a fire-rated insulated glass ceramic unit that also complies with energy codes. Temperature rise doors provide a barrier to radiant and conductive heat transfer.Īvailable in stainless steel frame finish options for increased design flexibility.īuilding codes clearly define hazardous locations where impact safety glass is required. In the U.S., the hose stream test is required for all fire ratings over 45 minutes (all fire ratings require it in Canada).Īvailable as a temperature rise door with Pilkington Pyrostop® fire-resistive-rated glass for 60-90 minute applications The cooling, impact and erosion created by the hose stream tests the integrity of the glass. Immediately following a furnace test, heated glass is subjected to water from a fire hose. A required characteristic of glass used as a wall.Ĭlassified and labeled by Underwriters Laboratories, Inc.® (UL), an independent product safety certification organization. Testing to the UL 10C standard more closely simulates real fire conditions.īlocks radiant and conductive heat transfer from one side of the glass to the other. 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. The time, in minutes or hours, that materials or assemblies can be expected to prevent flames and smoke from spreading.Īs heat develops within the source area, pressure within the enclosed room begins to build relative to the pressure outside.
