Soudal Gun Grade Expanding Foam

Gun Applied Polyurethane Expanding Foam for Gap Filling, Insulation and Sealing

Soudal Expanding Foam Gun Grade 750ml with Dura Valve is a one-component, moisture curing polyurethane foam designed for controlled application using a foam gun. This gun-grade formulation allows for precise dispensing, making it ideal for professional use in sealing, filling and insulating applications.

The foam expands after application to fill gaps, joints and cavities, providing effective thermal and acoustic insulation. It adheres to a wide range of construction materials including timber, concrete, brick, metal and most plastics.

The Dura Valve system improves usability and helps maintain product performance within the can. Designed for use with a foam applicator gun, this product allows accurate control over flow rate and expansion, reducing waste and improving finish quality.

Supplied in a champagne colour, this expanding foam is suitable for applications where a neutral finish is preferred.
