Reduce Risk, Protect Assets, and Maintain Compliance
We provide both fireproofing and firestopping solutions to protect structural components, seal penetrations, and maintain fire-rated assemblies across your facility.
Fireproofing
We provide fireproofing solutions designed to protect structural steel and critical building components from high temperatures during a fire.
- Intumescent fireproofing (expands under heat to protect surfaces)
- Cementitious fireproofing (spray-applied for structural protection)
- Fireproofing spray applications for industrial and commercial systems
Firestopping
Firestopping systems are essential for sealing penetrations and joints, helping contain fire and smoke within designated areas.
- Joint firestopping
- Fire caulking for penetrations and gaps
- Firestopping systems and fire barrier systems
- Fire safing for wall and floor assemblies
Wall & Curtain Wall Insulation Systems
We install fire-rated insulation systems designed to maintain the integrity of walls, curtain walls, and building envelopes.
- Curtain wall insulation systems (maintain fire ratings and limit vertical fire spread)
- Cladded facade wall insulation (enhances fire resistance and protect exterior assemblies)
- Rigid fiberglass board insulation (supports fire-rated systems with durable performance)
Complex Projects Deserve Straightforward Solutions
We make even the toughest jobs easier with expert guidance and tailored support from start to finish.
Key Areas That Require Fireproofing and Firestopping Systems
Fireproofing and firestopping systems are essential for maintaining safety and meeting building code requirements across industrial and commercial facilities. These systems are designed to protect structural components and prevent the spread of fire and smoke through critical areas of your building. Proper installation ensures your facility remains compliant, reduces risk, and is prepared for inspection.
- Wall and floor penetrations for piping, conduit, and cable systems
- Structural steel requiring fireproofing protection
- Expansion joints and gaps between building materials
- Curtain wall and exterior wall assemblies
- Mechanical, electrical, and plumbing (MEP) system openings
