Fire-protective glass (glazing that defends against the spread of flames and smoke), such as TGP’s FireLite fire-rated glass ceramic, is available with 20 to 180 minute fire ratings for door assemblies. It can often be used in the maximum size (as tested by an independent testing agency) in fire-rated doors depending on the required fire rating. However, in some cases building codes limit fire-protective glass to 100-square inch lites in doors with temperature rise requirements, such as those in exit enclosures and passageways.
If the design calls for a full-lite glazed door to boost visibility, improve wayfinding or create a bright, open entry, a code-approved alternative is fire-resistive glass, such as TGP’s Pilkington Pyrostop fire-rated, impact safety-rated transparent wall panels. Since it can defend against flames, smoke and heat transfer, it is not limited to 100-square inches, even in doors with temperature-rise requirements.
There are also a number of compatible fire-protective and fire-resistive door and framing systems that are available in single leaf or double leaf design. Products like TGP’s Fireframes® Designer Series, Fireframes Heat Barrier Series and Fireframes Hardwood Series not only provide a sleek, modern alternative to traditional hollow metal steel frames, but are also available in a wide array of colors, materials, and finishes. Their design flexibility helps prevent scenarios in which the fire-rated frames provide the necessary fire protection, but the frame color and material conflict with neighboring door, window and curtain wall applications.
