BOSS 334 Polyurethane Foam SPRAY
BOSS 334 Polyurethane Foam Spray is a high-performance, multi-purpose expanding foam designed for sealing, insulating, and filling gaps in a wide range of construction and renovation projects. This versatile foam spray is formulated to provide superior adhesion, durability, and thermal insulation, making it an essential solution for professionals and DIY enthusiasts alike.
When applied, BOSS 334 expands rapidly to fill cavities, cracks, and joints, creating a strong, airtight seal that effectively blocks out air, moisture, and noise. This makes it ideal for use in sealing around windows and doors, insulating walls and roofs, and filling gaps around pipes, conduits, and other penetrations. The foam's high expansion capability ensures it can reach and fill irregular and hard-to-access areas, providing comprehensive coverage and enhancing the energy efficiency of buildings.
BOSS® 334 window & door, minimal-expanding gun foam is a one-component, ready-to-use polyurethane foam, formulated to seal the gaps around windows and door frames, and other rough openings. It expands in contact with air to generate an effective seal and is proven not to distort or bow window and door frames.
