Our fire door foam is a PU expanding foam designed to seal the gaps between walls and fire door frames, providing up to 60 minutes of fire protection on its own. It replaces traditional mineral fibre wool and is far quicker to apply, saving installers an average of around 12 minutes per door, which has made it a trusted choice with professional fitters. Used together with FAS intumescent acrylic or silicone sealant and standard packers, it has been tested to achieve fire ratings of up to 120 minutes.

Alongside the foam itself, this collection brings together the full installation kit: PU foam applicator guns, extension and tapered nozzles for awkward gaps, foam gun cleaner, plastic packers for correct frame positioning, and a fire door gap gauge for checking the gaps. It is a complete, fire-door-specific solution for fitting and sealing frames quickly and compliantly.

What is fire door foam used for?
Fire door foam seals the gap between a fire door frame and the surrounding wall. As a PU expanding foam, it fills the void quickly and, unlike standard expanding foam, is designed and tested to maintain fire protection at that critical junction.

How long does it take to apply, and why use it instead of mineral wool?
The foam is quick to apply, taking only a few minutes per frame, and replaces the slower job of packing mineral fibre wool. On average, it saves installers around 12 minutes per door while still sealing the gap to the required standard.

What fire rating does it achieve?
On its own the foam provides up to 60 minutes of fire protection. When used together with FAS intumescent acrylic or silicone sealant and standard timber or plastic packers, it has been tested to achieve up to 120 minutes. Always follow the tested system and the door manufacturer's specification.

What else do I need to fit a fire door frame?
This collection includes the supporting kit: a PU foam applicator gun, extension and tapered nozzles, foam gun cleaner, plastic packers for positioning the frame, and a gap gauge ruler for checking the door gaps.
