DOW Great Stuff PRO Polyurethane GUN Foam Fixer Screw TOP FOR GUN Window AND Door 750ml 6001123

This 750ml polyurethane gun foam is supplied in a screw-top canister designed for use with an applicator gun. The low expansion characteristic makes it suitable for fixing and sealing window and door frames, helping to minimise frame movement and reducing the chance of distortion during installation.

On site, it is typically applied to fill gaps, provide insulation, and help weatherproof around window or door openings in masonry, timber, or uPVC. Its controlled application helps limit waste and excess clean-up, and the foam adapts to surface irregularities for a complete fill, allowing for effective finishing after curing.
