General purpose gap filling with high thermal and acoustic insulation. This moisture curing, self-expanding polyurethane foam adheres to most common building materials and is resistant to water, heat, and ageing. It can be cut, sanded, plastered, and painted once cured. Ideal for filling and insulating holes, voids, gaps, and joints in construction, around window and door frames, and for insulating pipes and electrical wiring. The gun grade foam offers a high gap-filling yield and is suitable for precise application with a compatible gun. It provides excellent stability with no shrinkage or post-expansion and is suitable for both interior and exterior use.
