Professional Expanding Foam – High Performance PU Gap Filling Insulation Foam

Professional Expanding Foam – High Performance PU Insulation Foam

Professional Expanding Foam is a premium quality, one-component polyurethane (PU) foam designed for professional builders, roofers, joiners, plumbers, and DIY users. It provides excellent thermal and acoustic insulation while creating a durable, airtight seal around windows, doors, pipes, ducts, and construction joints.

Ideal for filling large gaps, cavities, cracks, and voids, this expanding foam cures quickly to form a strong, rigid structure that can be trimmed, sanded, plastered, or painted once fully cured. Its superior adhesion allows it to bond to most common building materials including timber, brick, masonry, concrete, stone, metal, and many plastics.
