Specialist pitched roof insulation for commercial, industrial and agricultural buildings in Coleraine and across Northern Ireland — installed by ThermoFoam, part of the Duratite Group.
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.
