List of featured suppliers of PIPE SLEEVES Intumescent on Building Products Index
Pipe sleeves, intumescent refer to protective covers that contain an expanding material that swells when exposed to high temperatures. These sleeves are used to prevent the spread of fire and smoke through pipes and other penetrations in walls, floors, and ceilings. When exposed to flames or extreme heat, the intumescent material in the sleeve expands, closing off the opening and preventing the spread of fire and smoke. This helps to protect the building and its occupants from the dangers of a fire.
