Curtainwall Insulation

By Owens Corning LLC.

Owens Corning High Density Fiberglass ProductsPerimeter fire containment systems are designed to prevent fire and hot gases from entering the room above the room of origin through voids that exist at the intersection of a rated floor assembly and a non-rated exterior wall. An unprotected void at the edge of the slab potentially creates a pathway for fire and/or smoke to spread from floor to floor in a building. Although such joints are often small, 2"-3" wide, consider that for a building with a floor plate size of 200' x 200', 800 lineal feet, an unprotected joint 3" wide creates 200 square feet of open area along the perimeter that will allow smoke and hot gasesto flow freely from floor to floor. Fire can also pass through voids or combustible materials in the curtain wall itself. Given that the condition exists at each floor, the potential for fire and smoke spread is significant. The Owens Corning® Enclosure Solutions Thermafiber® Impasse® Curtain Wall InsulationSystem, a patented perimeter fire containment system, has all of the products and details necessary to design and construct aluminum-framed curtain wall perimeter fire containment systems n accordance with ASTM E2307 and the International Building Code (IBC)1 to prevent fire from spreading from floor to floor.
