FireLite Plus® WS is a nominal 5/16” (8 mm) thick laminated glazing material listed for use in doors, sidelites, transoms and borrowed lites. When acceptable to the local Authority Having Jurisdiction (AHJ), FireLite Plus WS may be used in combination with TYCO Model WS Window Sprinklers as an alternative to fire rated assemblies requiring a 2-hour rating. Unlike tempered glass, using FireLite Plus WS glazing eliminates TYCO’s WS Special Application Sprinkler requirement for keeping combustible materials a minimum of 2" from the glass face (typically accomplished by incorporating a minimum 36" ponywall).

TYCO Model WS Window Sprinklers are the first to be specifically listed to provide complete wetting and coverage for FireLite Plus WS glass for windows and glazing using closed sprinklers. As part of the sprinkler testing, the gas flow required to achieve the time/temperature relationship specified in ASTM E119 was established in a test furnace. A window assembly protected with the TYCO Model WS Window Sprinklers was then installed in the test furnace, and the same gas flow conditions were maintained for a two-hour test period. No cracking or visible damage to the window was permitted during the test period, even when a hose stream was directed at the window.
The Model WS Window Sprinkler and FireLite Plus WS glazing can be used as interior protection of windows or glazing in a sprinklered or non-sprinklered building in accordance with Section 104 of the International Building Code (IBC) (“Alternate Materials, Design and Methods of Construction and Equipment”). TYCO Model WS Window Sprinkler and FireLite Plus WS glazing can be used as an open sprinkler for “Outside Sprinkler Protection against Exposure Fire”, using the design requirements of NFPA.

FireLite Plus (including FireLite Plus WS) is classified and labeled by Underwriters Laboratories, Inc.® and Underwriters Laboratories of Canada. File number for labeled fire-rated assemblies is R13377. Tests performed in accordance with:
FireLite Plus consists of two pieces of FireLite glass ceramic laminated together. Because FireLite is made from transparent glass-ceramic, it differs in color from float glass. FireLite appears to have a warmer earth tone when compared to the blue green tint of typical float glass. However, like float glass, FireLite ceramic will not demonstrate a highly perceptible color once installed in a frame. Additionally, FireLite products are manufactured in three distinct surface grades (Premium, Standard and Obscure) that are best reviewed prior to specification Please contact TGP at 800.426.0279 or tgp.sales@allegion.com to request a sample kit.

Liability Disclaimer: As with any specific fire-rated glazing and sprinkler application, the installation instructions for the glazing and sprinkler system must be precisely followed. If there are additional local or jurisdiction installation standards / codes for window sprinklers on glazed window systems, this document and the TYCO Model WS Sprinkler documentation does not relieve the designer / installer from these requirements. Consult your local AHJ to verify if or when these additional guidelines must be followed.

The time, in minutes or hours, that materials or assemblies can be expected to prevent flames and smoke from spreading.
As heat develops within the source area, pressure within the enclosed room begins to build relative to the pressure outside. 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.
Blocks radiant and conductive heat transfer from one side of the glass to the other. A required characteristic of glass used as a wall.
Classified and labeled by Underwriters Laboratories, Inc.® (UL), an independent product safety certification organization.
Immediately following a furnace 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. In the U.S., the hose stream test is required for all fire ratings over 45 minutes (all fire ratings require it in Canada).
Available as a temperature rise door with Pilkington Pyrostop® fire-resistive-rated glass for 60-90 minute applications
Temperature rise doors provide a barrier to radiant and conductive heat transfer.
Available in stainless steel frame finish options for increased design flexibility.
Building codes clearly define hazardous locations where impact safety glass is required. 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.
FireLite IGU is a fire-rated insulated glass ceramic unit that also complies with energy codes. 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.
Withstands continuous temperatures to 1292° F for use in high efficiency heating appliances.
The ability of glass ceramic to withstand sudden heating, cooling, or both without cracking, shattering or exploding out of the frame.
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 7.62mm rifle lead core full metal copper jacket, military ball).
The capacity of an element in a building structure to support a weight in addition to its own.
Listed and labeled by Intertek, an independent assurance, testing, inspection and certification organization.
Glazing designed to increase the amount of time required to gain entry. This additional time is intended to allow for the enactment of lock-down protocols and to allow for the arrival of emergency response teams. May be used in areas with high risk of prolonged attack or in critical areas such as vestibules. Forced entry resistant glazing should also resist penetration from hand-held or hand-thrown objects such as hammers, crowbars, bats, knives, bricks and rocks.
