Firestopping systems are a critical part of commercial construction, helping maintain the integrity of fire-rated walls, floors, and building assemblies. Properly installed systems help limit the spread of fire, smoke, and sound while supporting the life safety requirements established by today’s building codes.
Division 7 Waterproofing installs fire, smoke, and acoustical rated sealants and fillers for a wide variety of commercial applications. Our experienced crews understand the importance of proper material selection, tested assemblies, and precise installation to help each system perform as designed.
Firestopping for Commercial Buildings
Every penetration, expansion joint, and transition within a fire-rated assembly represents a critical detail. Firestopping systems are designed to restore the fire rating of these openings, helping contain fire and smoke while maintaining the integrity of the overall building envelope.
Our crews work closely with contractors and other trades to ensure firestopping systems are installed where required and coordinated with the surrounding construction.
