Fischer PU Foam is a high-quality, multi-purpose polyurethane foam used for sealing, filling, bonding, and insulating gaps and joints in construction and interior applications. Designed to offer superior expansion, adhesion, and thermal insulation properties, Fischer PU Foam is ideal for door and window frame installation, pipe penetrations, wall break-throughs, roof construction, and other cavity-filling tasks. It adheres to a wide range of building materials including concrete, brick, wood, metal, and certain plastics.

The foam expands upon application and cures with atmospheric moisture, forming a durable, airtight, and water-resistant barrier. Once cured, it can be trimmed, cut, sanded, and painted.
