MapePUR Universal Foam M/G is a self-expanding polyurethane foam for filling and insulating suitable gaps in building work. When a door frame has been fitted or a service passes through a wall, irregular voids can remain that are difficult to fill neatly with rigid materials. This foam expands into those spaces to provide a lightweight, trimmable insulating fill.
It is useful on both new construction and refurbishment jobs, particularly around securely fixed window and door frames and compatible building-service openings. Its thermal and acoustic insulating properties make it more useful than an ordinary cosmetic gap filler where air movement or noise transfer is also a concern.
A shaped void or uneven gap often needs a material that conforms to its profile. MapePUR Universal Foam expands to occupy suitable spaces, unlike a rigid patching compound or a narrow decorative sealant bead. Use it for insulation and filling, not for structural fixing or creating a weatherproof joint on its own.
Allow sufficient room for foam expansion, follow the product's application conditions and protect cured material against prolonged UV exposure. This is not a substitute for mechanical fixings, a tested fire-rated penetration system or the external waterproofing and weather-sealing detail. Confirm the relevant manual or gun application format of the supplied variant.
What is MapePUR Universal Foam used for?
Filling, insulating and sealing gaps around frames, services, cavities and other construction details.

Yes. Once cured it can be cut, sanded and painted or covered with a suitable finish.
Does it bond to polyethylene or silicone?
No. Those substrates are excluded.
Should the foam be protected from sunlight?
Yes. Cured polyurethane foam should be protected from direct UV exposure.
