“Underhill’s knowledge and reputation gives assurance that a building is properly firestopped.”
Flames build and spread from room to room following a path within walls, floors and ceilings passing through unsealed construction joints, mechanical penetrations and shaft ways.
Unfortunately, the inadequacies of an improperly installed or omitted firestopping / smoke sealing life safety system may not be known until tested in an actual fire. Fire-rated ceilings and walls can cosmetically hide inadequately sealed penetrations made by electrical wiring, sprinkler, pipe, or duct work. Mechanical shafts and wall joints provide an unhindered environment for the rapid flow of smoke or fire from room to room. For all of these reasons, building owners, designers and contractors constructing or renovating buildings are turning more and more to the expertise of A.F. Underhill’s pioneering team of professionals.
International and local building and fire codes are annually becoming more stringent in all aspects of life safety systems. Fire stopping / smoke sealing is among the cutting edge technologies upon which codes are focusing. The positive sealing of fire barriers is no longer optional, the sealing of all voids is now mandatory in both new and existing buildings. As codes, materials, and applications evolve, you can rely on A.F. Underhill to keep pace with these new developments.
