Euro SIL Multi Purpose PU Foam Sealant - 750ml

In construction and renovation, the small spaces are where big problems hide. The gap around a newly fitted window frame. The cavity beside a door installation. The joint between a wall and a structural fitting. Left unfilled, these openings become pathways for cold air, heat loss, unwanted noise, moisture, and pests. They're the invisible weak points in an otherwise solid build — and they deserve a solution that takes them as seriously as the rest of the work.

Euro SIL Multi Purpose PU Foam is that solution. This 750ml expanding polyurethane foam is engineered for the full range of filling, sealing, and insulating tasks that construction and renovation demand. From installing door and window frames to sealing wall cavities, joints, and structural openings, it expands precisely to fill the available space, bonds firmly to surrounding surfaces, and cures into a dense, durable material that holds its form long after the job is done.

The performance goes well beyond simply filling a gap. Once cured, Euro SIL PU Foam delivers genuine thermal insulation — reducing heat transfer and helping maintain consistent indoor temperatures, which translates directly into lower energy costs over time. It also provides effective sound insulation, dampening the transmission of noise through walls, frames, and cavities to create quieter, more comfortable interior spaces. And its strong adhesion across a wide range of building materials means you can apply it confidently on brick, concrete, wood, metal, and more.

The expanding foam format makes it uniquely suited to irregular gaps and hard-to-reach spaces where rigid materials simply can't conform. It seeks out the full depth and width of any opening, ensuring complete coverage without voids or weak spots. The result is a seal that is airtight, watertight, and built to last through the demands of daily use and changing weather conditions.

Whether you're a contractor finishing a professional installation or a builder who won't cut corners on quality, Euro SIL PU Foam gives every gap the treatment it deserves.

Build tight. Insulate well. Trust Euro SIL.
