Intumescent sealants are specialized materials used in construction to enhance fire safety. When exposed to high temperatures, these sealants expand significantly, forming a thick, insulating char that helps prevent the spread of smoke and flames through gaps and joints in buildings. They are commonly applied around electrical outlets, pipes, and other penetrations in fire-rated walls. These sealants are essential for maintaining the integrity of fire-rated assemblies, ensuring that structures comply with safety regulations. Available in various forms, such as caulks and sprays, intumescent sealants are easy to apply and can be painted over, making them a practical choice for both new constructions and renovations.
