Pyroplex Fire Only Intumescent Seal | Intumescent Strip

An intumescent is a substance that swells as a result of heat exposure, thus increasing in volume and decreasing in density. Intumescents are typically used in passive fire protection and require listing, approval and compliance in their installed configurations in order to comply with the national building codes and laws.
