Firestopping

Self-Seal® GG-266 is a single-component, neutral cure, non-slumping intumescent silicone caulk that is designed to seal combustible service penetrations in fire-rated walls and floors. When exposed to temperatures above 150°C (300°F), it will begin to expand. As the combustible penetrating item softens and collapses under fire conditions, the silicone composition will rapidly intumesce to fill the void with a patented char composite that contains expanded graphite. Features: Intumescent Silicone (expands when exposed to temperatures above 150°C (300°F)) Self-Seal GG-266 has achieved GREENGUARD GOLD Certification Non-sag silicone Water-resistant before, during, and after cure Freeze-thaw stable Protects your wall & floor openings Tested at positive pressure to simulate the pressure differentials that can occur in a fire situation Self-Seal GG-266 seals combustible service penetrations in fire and smoke rated wall or floor separations. Basic uses include firestopping: Up to 2” PVC, ABS, IPEX Aquarise, PEX, FRPP, and CPVC penetrations - only a minimum 5/16” annular space needed Up to 4” PVC, IPEX XFR 15-50 PVC, Royal Pipe HRS2550, ABS, and CPVC pipe penetrations through conical or cored openings in concrete floor slabs
