Multifoil Loft Insulation

Thin, multi-layered reflective insulation for Guildford lofts where space is tight — ideal for room-in-roof conversions, sloping ceilings and awkward low-headroom spaces.

Why multifoil

Space-saving performance for Guildford roofs

Multifoil insulation is built from multiple reflective foil layers with insulating wadding between them. It reflects radiant heat back into the home and delivers useful thermal performance in a fraction of the thickness of traditional insulation.

That slim profile makes it the natural choice where depth is limited — loft conversions, rooms in the roof, sloping ceilings and dormers — and it can be combined with other materials for a complete solution.

Good to know

Multifoil needs an air gap on at least one side to work properly, so correct installation matters. Our own fitters handle that detail so you get the performance the product is capable of.

FAQs

Common questions

When is multifoil the right choice?

When headroom or depth is limited — conversions, sloping ceilings, dormers — or where you want to add performance without losing much space.

Does it replace normal insulation?

Sometimes, and sometimes it complements it. In a standard open loft, mineral or wool laid to 270mm is usually more cost-effective. We advise per property.

Does installation affect how well it works?

Yes — multifoil relies on a correct air gap and sealed joints. Because we fit it ourselves, that is done properly.
