Specialist pitched roof insulation for commercial, industrial and agricultural buildings in Berwick-upon-Tweed and across Yorkshire & the North East — installed by ThermoFoam, part of the Duratite Group.
Commercial pitched roofs around Berwick-upon-Tweed 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.
