Rubson Expanding Foam - Insulation Foam - 21 L Expansion - For Filling Gaps and Cavities
Rubson Expanding Foam provides optimal and long-lasting insulation by effectively filling cavities, gaps, and interstices, while ensuring exceptional thermal and acoustic continuity between windows and doors and masonry. Thanks to its generous 21L expansion capacity and its clean formula, which emits no isocyanates during extrusion, it adheres to most building materials. Ultra-versatile, it can be sanded, cut, plastered, and painted once hardened. Designed with a responsible approach, featuring an aerosol can and cap made from recycled materials, it also offers exemplary extrudability, even vertically, for a professional and durable result.
