Aerosol Polyurethane Foam

Aerosol polyurethane foams provide a fast, convenient way to fill, seal and insulate. Supplied in pressurised cans, these expanding foams are ideal for quick application in construction, repairs and general maintenance. At CFS Fibreglass, we stock fire-retardant B1, B2 and B3 grades, ensuring you can choose the right level of performance and safety for your project.

Once dispensed, the foam expands to fill gaps, sets rigid and provides excellent adhesion to most building materials. It offers reliable insulation, soundproofing and structural reinforcement, while remaining lightweight and easy to trim or sand once cured.

Whether you’re sealing joints, filling voids, improving thermal insulation or carrying out repair work, our aerosol polyurethane foams deliver a practical, professional finish. Each can is supplied ready to use, with applicator nozzles included for simple, controlled application.

Each 500ml tin gives a yield of about 22 litres.
