Construction Specialties - Firestopping

Firestopping is a passive fire protection system applied to construction joints, openings, and penetrations in a fire-rated wall or floor assembly. A properly installed firestop system restores the fire-resistance rating of the separation, protecting the structure against the spread of fire.

At Antex Western, we proudly carry firestopping products from Rectorseal, Hilti, 3M and STI, with in-house installers certified in these brands. We work with building owners/managers, general contractors, mechanical contractors and electrical contractors to help protect against loss of life and property.

Our firestopping service include:

• Smoke seals applied to joints, openings and penetrations through non-rated wall or floor assemblies
• Mechanical through penetrants
• Electrical through penetrants
• Structural through penetrants
• Control/Expansion joints
• Junctions between fire-rated wall and floor assemblies
• “Head-of-Wall” joints, where non-load bearing walls meet the underside of floor assemblies
