PENOSIL 750ml Universal Strawfoam 265

The PENOSIL 265 is a multipurpose, ready-to-use polyurethane straw foam designed for general construction and DIY applications. Unlike gun-applied foams, this hand-held version requires no additional tools, making it the perfect choice for one-off filling tasks, insulation repairs, and sealing large gaps where high expansion is needed to fill voids quickly.

Key Features
High Volume Expansion: Features a high post-expansion rate (<150%), making it highly efficient at filling large holes, cavities, and irregular penetrations with a single pass. Superior Insulation: Provides a high thermal insulation value (0.033 W/m·K) and a significant sound reduction index of 62 dB, helping to eliminate draughts and reduce noise transfer. Universal Adhesion: Bonds strongly to most common building materials, including wood, concrete, stone, plaster, metal, PVC, and polystyrene. Airtight & Non-Shrinking: Once cured, it forms a stable, airtight seal that does not shrink or pull away from the edges, ensuring the long-term integrity of the thermal barrier. Low Curing Pressure: Despite its high expansion, it exerts low pressure during the curing process (<1.5 kPa), reducing the risk of deforming lighter construction elements.
