For sustainable and lasting bonds

Our 858 Recycling Pistolen Schaum combines sustainability and long-term durability in one product. The foam is made with over 15% pre-polymer, which is recycled from collected polyurethane foam cans. The assembly foam offers the highest level of adhesion to all common building materials, making it ideally suited for filling recesses and openings in walls – and indeed cavities of any kind. Due to its exceptional resistance to moisture and temperature fluctuations, 858 Recycling Pistolen Schaum can also be used for loft conversions and roof insulation. The special valve makes the product easier to apply with a foam gun. And the results it delivers are a success on a visual level, too.
