BOSTIK TIGER is a single-component, hand-applied class B3 PU expanding foam in a 600 ml can for insulation and installation work in construction. It fills joints around window and door frames, partition walls, ceiling and floor gaps, and openings where pipes and cables pass through walls and floors. Applied straight from the can without a gun, the foam bonds well to concrete, brick, stone, plaster, wood, metal, EPS, XPS and uPVC.
