Fire-resistant caulk is a specialized sealant designed to withstand high temperatures and prevent the spread of flames and smoke. It is commonly used in construction to seal gaps and joints in walls, ceilings, and floors, enhancing the fire safety of buildings. This type of caulk is often made from materials like silicone or intumescent compounds, which expand when exposed to heat. Using fire-resistant caulk is essential in areas where fire barriers are required, such as around electrical outlets, pipes, and ducts. It helps maintain the integrity of fire-rated walls and ceilings, ensuring that they perform effectively during a fire emergency.
