Thin, multi-layered reflective insulation for Winchester lofts where space is tight — ideal for room-in-roof conversions, sloping ceilings and awkward low-headroom spaces.
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.
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.
When headroom or depth is limited — conversions, sloping ceilings, dormers — or where you want to add performance without losing much space.
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.
Yes — multifoil relies on a correct air gap and sealed joints. Because we fit it ourselves, that is done properly.
