Fire Retardent Expanding Foam 132658

EVO-STIK Fire Retardant Expanding Foam Filler is a one component polyurethane foam that is self-curing through the absorption of moisture from the atmosphere. It sets to form a semi-rigid structure, which flexes firmly, yet yields to vibration and joint movement. For interior and exterior applications, it is suitable for filling large, irregular or awkward gaps where a fire rating is needed, for filling gaps through fire reated insulation between brickwork and cladding and around ductwork, and for insulating and filling around door and window frames where a fire rating is necessary. The foam has excellent adhesion to wood, brick, stone, concrete, plaster, asbestos, wallboard, hardboard, and metal surfaces. It does not bond polythene, Teflon, silicone and other waxy materials. Features & Benefits Forms an airtight seal to prevent transmission of smoke. Fire rated to EN 1366-4. Fills and insulates large or small gaps. Excellent adhesion to most building materials.
