Low expansion polyurethane foam 750ml 105157

Professional sealing and insulation with Soudafoam Low Expansion

Soudafoam Low Expansion is a low-expansion polyurethane foam in a gun pack, designed for demanding applications in construction and renovation. It is characterized by excellent adhesion to most building materials – from concrete and brick, through wood and PVC, to aluminum. This is a versatile solution for both professionals and DIY enthusiasts who value precision and durability.

This foam boasts excellent thermal insulation (λ = 0.0356 W/m*K) and acoustic insulation (up to 58 dB), confirmed by tests from the i.f.t. Rosenheim institute. Low expansion minimizes the risk of deformation of structural elements, especially when installing window and door frames with thin profiles. This ensures controlled application and an aesthetic and functional end result. It contains a gas that is harmless to the ozone layer, making it an environmentally friendly choice.

Practical applications

Soudafoam Low Expansion will work in many situations:

• Window and door installation: Particularly recommended for sealing frames made of PVC and aluminum.
• Sealing building elements: Sills, shutters, thresholds, stairs – wherever a durable and flexible insulation is needed.
• Insulation of installations: Filling the space around central heating and water supply pipes reduces heat and noise loss.
• Filling gaps: Ideal for filling empty spaces in partition walls, frame structures and floor connections.
• Acoustic insulation: Use in floors, attics and roofs significantly improves the acoustic comfort of rooms.

Key product features

• Low expansion: Controlled volume increase minimizes the risk of pushing out structural elements.
• Excellent adhesion: Guarantees a durable connection with various building materials.
• High thermal and acoustic insulation: Provides thermal comfort and noise reduction in rooms.
• Short curing time: Allows for quick completion of installation work.
• Safety of use: Does not contain gases harmful to the ozone layer.
• Duravalve™ valve: Ensures the tightness of the packaging, optimal foam consistency and the ability to stop work without loss of performance.

The can capacity is 750 ml, providing a yield of up to 45 liters of foam (depending on environmental conditions). The product is available in yellow and is designed for application with a standard caulking gun.
