Pitched Roof Insulation in Coleraine
Specialist pitched roof insulation for commercial, industrial and agricultural buildings in Coleraine and across Northern Ireland — installed by ThermoFoam, part of the Duratite Group.
Pitched Roof Insulation for Coleraine businesses
Commercial pitched roofs around Coleraine lose heat through every gap between boards, rafters and details. Sprayed to the underside of the deck, foam seals junctions, valleys and penetrations in one continuous airtight pass — bringing the roof space into the thermal envelope without giving up internal room.
The system is matched to the build-up: Nexseal LE closed-cell where vapour control and rigidity matter, Sucraseal open-cell where the roof needs to breathe. Condensation risk is checked against BS 5250:2021, the install supports Part L upgrade targets, and handover includes the full written specification.

Pitched Roof Insulation in Coleraine — your questions
Closed-cell or open-cell for a pitched roof?
Depends on the build-up — closed-cell brings a vapour barrier and rigidity; open-cell breathability and acoustics. The survey determines which.
Will it help meet Part L in Coleraine?
Yes — the continuous airtight layer is an efficient route to Part L upgrade targets, documented for Building Control.
Do you insulate commercial pitched roofs only?
Yes — ThermoFoam works on commercial, industrial and agricultural buildings; we do not undertake domestic work.
