Firestopping

Firestopping is not just one material or item, but a complete fire protection system of various materials and components that seal openings and joints in fire-resistance rated wall and/or floor assemblies. Materials and components used may include mineral fibers, intumescents, cementitious mortars, silicone, urethane, firestop pillows, and rubber compounds.
