Intumescent Sealants Explained

Intumescent sealant, also known as fire mastic, adds an extra layer of passive fire protection to a building to slow the spread of fire and smoke. It is designed to reinforce the fire resistance of walls, floors, and door frames by sealing unprotected cavities such as linear joints and pipe penetrations. Intumescent sealants expand in volume when exposed to extreme heat, filling voids to form a tight seal, which prevents fires and smoke from spreading. The use of intumescent sealant is becoming increasingly popular as fire regulations become more stringent, since they are a versatile solution that can help protect a building’s structural integrity as well as reduce smoke-related casualties.
