Specialist flat roof insulation for commercial, industrial and agricultural buildings in Sandbach and across the North West — installed by ThermoFoam, part of the Duratite Group.
Flat roofs on Sandbach's commercial buildings are high-risk: interstitial condensation, deck rot and patchwork board insulation full of gaps. Sprayed from below, closed-cell foam forms one continuous layer that follows every upstand, penetration and detail — the gaps board systems always leave are simply never created.
Condensation risk is assessed against BS 5250:2021 before installation, and the system is chosen to suit the build-up: Nexseal LE closed-cell (λ 0.027 W/m·K) with its integral vapour barrier, or Sucraseal open-cell (λ 0.039) where breathability is required. Full documentation and a 25-year manufacturer warranty at handover.

Not every one — that's why condensation risk is assessed against BS 5250:2021 first, and the system specified to suit the specific build-up.
