Knauf Professional All-Season PU Foam 850 ml

Knauf professional foam is a one-component, all-season polyurethane sealant for mounting, sealing, and insulating joints. Supplied in an 850 ml aerosol can, it offers high adhesion to most building materials including concrete, brick, plaster, wood, and plastic. The foam expands evenly, forms a fine-pored structure, and does not deform surrounding elements due to zero secondary expansion. Contains flame retardant additives. Ideal for window and door installation, panel fixing, and gap filling.
