Short, practical answers about using foil as a replacement after spray foam removal, with links to further guidance where helpful.
It can be, especially where headroom is limited. A post-removal survey checks vapour control and structure to confirm suitability; we can also explain other replacement insulation options.
Foil reflects radiant heat back into the living space rather than absorbing it. Installations are usually under rafters or across loft voids where a thin, low-profile layer is needed.
Not if fitted correctly. Foil needs appropriate vapour control and ventilation to avoid trapped moisture, so we assess ventilation as part of the removal process and before installing.
Foil itself is not a substitute for required fire measures. Installers must maintain clearances and use suitable materials so the overall roof build-up meets safety requirements.
For a typical loft the work is usually completed in a day with low disruption. Any preceding spray foam removal or preparatory roof work will affect the timescale.
