Description
B3 Fill & Fix Foam is a quick, economical, and easy to apply foam, improving draught and heat insulation while filling irregular gaps, fixing frameworks, and deadening sound. Once cured, it can be cut, sawn, plastered, and sealed. It adheres to most common building materials, including wood, concrete, stone, plaster, metal, PVC, and polystyrene. Ideal for fitting doors, windows, insulating pipes, and filling gaps, it can reduce the need for mechanical fixings. Available in 500ml and 750ml aerosol cans or a 750ml gun-grade canister compatible with standard gun foam applicators (BDAG1 or BDAK45). It conforms to DIN4102 Class B3, meaning it has no fire-resistant additives.
