Superfoil Multi-Layer Insulation

High performance in a slim, breathable build-up

Superfoil is a multi-layer foil insulation system made up of reflective foils bonded to insulation wadding. It works by combining conductive insulation with radiant heat reflection, giving strong thermal performance in a much slimmer profile than mineral wool.

We fit it most often to the underside of rafters, room-in-roof conversions and after spray foam removal, where a breathable, low-profile solution preserves headroom and lets the roof timbers ventilate properly.

Every install is taped and lapped to manufacturer spec so the vapour control layer is continuous. That keeps the thermal performance high and stops interstitial condensation forming behind the insulation.
