Low Expansion

Gun Foam Low Expansion is a one-component, self-expanding polyurethane gun foam suitable as an insulation and assembly foam and for creating seals between different construction materials and building components. It cures through atmospheric moisture to form a durable foam mass.

Applications:

• Specially developed for durable sealing and filling of connection joints, seams, gaps and openings in interior and exterior façades, cavity walls, partition walls, ceilings, floors and roof sections.
• Filling and sealing pipe and service penetrations in façades, walls, floors, ceilings and roofs.
• Sealing and filling installation spaces around prefabricated and façade elements such as window frames and façade systems.
• Sealing and filling connections between metal, plastic, wood, masonry, gypsum, stone and concrete elements.
• Sealing connections in timber-frame and plaster construction.
• Bonding and sealing insulation boards/panels and other sheet materials in roof, façade, wall and floor constructions.
• Sealing connections around roof ridges, eaves, chimneys, drainage ducts, dormers, extensions and more.
• Filling, sealing and insulating cavities and openings in walls, façades, floors, ceilings and roofs.

Properties:

• Low post-expansion after application.
• Excellent adhesion to many materials, including stone, concrete, wood, gypsum, plaster and masonry, metal and various plastics such as polystyrene, rigid PU foam, polyester and rigid PVC.
• Low-expansion quality with reduced filling expansion during curing.
• High yield: approximately 45 litres when freely expanded.
• Versatile: fills, seals, bonds, installs and insulates.
• Very low emissions, certified in accordance with VOC emission class A+.
• Excellent acoustic and thermal insulation properties.
• Fast-curing, fine-cell polyurethane foam that is easy to process and cut.
• Durably resistant to weather, water, moisture and ageing; does not rot.
