Soudal Soudafoam Gap Filling Foam Gun Grade

High-Yield Polyurethane Foam for Sealing and Insulating Gaps

Soudal Soudafoam Gap Filling Foam Gun Grade is a one-component, moisture-curing PU foam designed for precise application using a foam gun. It expands to fill and insulate joints, gaps, and cavities in construction, offering excellent thermal and acoustic insulation. Suitable for use around window and door frames, wall penetrations, and general void filling.

Key Features & Benefits

• High Expansion: Expands to effectively fill gaps and cavities for improved insulation.
• Precise Application: Gun-grade format allows for controlled dispensing and minimal waste.
• Thermal & Acoustic Insulation: Improves energy efficiency and sound dampening in buildings.
• Strong Adhesion: Bonds to most construction materials including concrete, wood, brick, and metals.
• Moisture Curing: Reacts with humidity to cure into a durable, semi-rigid foam.
