Fire sealant is a specialized material designed to prevent the spread of fire, smoke, and heat through openings and joints in buildings. It is commonly used in construction to seal gaps around pipes, ducts, and electrical outlets, ensuring that fire cannot easily pass through these vulnerable areas. This sealant is typically made from fire-resistant compounds that can withstand high temperatures. When exposed to heat, fire sealant expands and hardens, creating a barrier that helps protect the structural integrity of a building and enhances overall safety for its occupants.
