SuperFoil multifoil — SF19+ and SF40 systems.
Multifoil insulation neatly installed and detailed. We work with the SuperFoil range — including SF19+ and SF40 — to suit the loft, the budget and the result you're after.
- Lofts where keeping the floor clear of mineral wool matters
- Rooms-in-roof or sloped sections needing slim, high-performance insulation
- Top up over existing mineral wool for added performance
- Homeowners who want a clean, tidy finish
SF19+ and SF40 — what's the difference?
- • SF19+ — multi-layer multifoil suited to most UK lofts; great all-rounder for thermal and radiant performance.
- • SF40 — thicker, higher-spec multifoil for the strongest performance where space and budget allow.
We'll recommend the right system after inspecting your loft — never up-sell what you don't need.
