ASHRAE Standard 90.1 requires Continuous Insulation (CI) be used for all commercial and some residential buildings in the United States. Continuous insulation is defined in 90.1 as “insulation that is continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope”.Learn More
ASTM E2307 measures the ability of perimeter fire barrier systems to maintain a seal and prevent interior fire spread as the exterior wall assembly deflects and deforms during fire exposure. The ASTM E2307 test exposes the joint to fire from the room of fire origin and the exterior wall to fire from both the interior and the exterior as the fire plume exits the room of fire origin through a window opening. ASTM E 2307 determines the period of time that the perimeter fire containment system will limit flame penetration through the opening between the exterior wall assembly and the floor assembly.Learn More
NFPA 285 is required in the International Building Code (IBC) in multiple situations. The NFPA 285 test is to determine that combustibles, when exposed to fire on the exterior face of the wall, do not spread flame over the surface or through the core of the otherwise non-combustible wall assembly.Learn More at NFPA.org
Owens Corning® Enclosure Solutions deliver buildings that perform without compromising design. Take a look at a few key case studies below.
Owens Corning® Thermafiber® RainBarrier® 45 mineral wool insulation was used in the masonry cavity wall construction to minimize the loss of hot and cold and maximize energy efficiency, thermal insulation, fire protection and acoustical control.Download Case Study
Owens Corning® Thermafiber® RainBarrier® 45 Continuous Insulation was specified in the wall assembly to deliver thermal protection and moisture resistance properties that help control the infiltration of rain and moisture that can lead to rot and mold.Download Case Study
