Our firestopping services create effective barriers against the spread of fire, smoke, and toxic gases. These firestop applications include Top of Wall, demising wall, and even slab edge. We can produce engineered sign offs for any detail or work with you to find the right solution.
TOP OF WALL: When concrete blocks meet a roof deck or floor above, we have to insulate and firestop it.
SLAB EDGE: We install mineral wool to the thickness of the floor at a 50% compression, then apply a firestop product to protect from flame and smoke spread.
DEMISING WALL: This is where suite walls meet an outside wall. We have to protect the spread of fire, so we install mineral wool and apply a sprayed firestop product.
