What Are Fire Collars and Why Are They Crucial for Fire Safety?
Fire collars are passive fire protection devices designed to prevent the spread of fire and smoke through walls and floors where plastic pipes pass. Installed around pipes that penetrate fire-rated assemblies, these collars contain intumescent material that expands during high heat, crushing and sealing the pipe. Fire collars are a code-required safety measure in many residential, commercial, and industrial buildings. They’re especially vital in multi-story structures where fire can quickly move between floors. Properly installed fire collars help maintain the fire resistance rating of walls or floors and give occupants more time to evacuate safely.
