Intumescent fire door seal strip Fire stop compound
The intumescent fire door sealing strip is a type of fire-resistant material that is used to seal the gaps around a fire door. It is designed to expand and form a seal when exposed to heat, preventing the spread of fire and smoke through the gaps. This door seal is typically made of a combination of intumescent material and a fire-resistant sealant, and is installed around the edges and bottom of the door. When a fire occurs, the heat causes the intumescent material to expand, filling the gaps and creating a barrier against the fire. This helps to contain the fire and protect the occupants of a building. Intumescent fire door seal strips are an important component of fire safety systems in commercial and residential buildings.
