Fire caulking
Fire-rated sealant applied to joints and gaps in fire-rated walls, including the top-of-wall joint where block meets the deck, to slow the spread of fire and smoke.
Fire safing
Mineral wool packed firmly into openings and gaps, then sealed over with fire-rated caulk.
Fire sealing
Sealing pipe, conduit and cable penetrations through rated walls so the wall keeps its fire rating.
Fire foam (option)
Fire-rated expanding foam for irregular gaps and voids where fire blocking is required. Ask us if foam is right for your project.
Our process
- Clean the opening.
- Pack mineral wool firmly.
- Apply fire-rated caulk on both sides of the wall.
