Pitched metal cathedral roof externally insulated with a continuous vapour and air tight rigid thermoset DCT PIR insulation board supported by purlins, a safety mesh or strapping. The ProctorGeo HC9 drainage mat installed between the roof sheet, and above the vapour permeable ProctorWrap HTS sarking, provides for drainage and acoustic attenuation of rain noise.
Pitched metal cathedral roof externally insulated with a continuous vapour and air retarder faced mineral fibre insulation blanket supported by a safety mesh or strapping. The full thickness of the insulation is maintained using a rigid DCT XPS thermal break at each purlin. The ProctorGeo HC9 drainage mat installed between the roof sheet, and above the vapour permeable ProctorWrap HTS sarking, provides for drainage and acoustic attenuation of rain noise.
Flat CLT roof protected by a self-adhered vapour permeable Wraptite SA sarking, insulated externally with a non combustible Vulcanwool stonefibre insulation that maintains the CLT roof at a stable temperature. The roof system is clad with a pitched metal roof supported by a substructure with a vapour permeable ProctorWrap HTS sarking draped under roofing battens provides drainage of any moisture below the roof sheet.

A "cold roof" design protected by an exposed waterproof membrane, continuously ventilated from ridge to eaves below the roof structural sheathing board, insulated between the joists/rafters, with a ProctorPassive SmartVap intelligent air barrier membrane at the ceiling forming a continuous air and vapour control layer.
A "warm roof" design protected by an exposed waterproof membrane, continuously insulated by a rigid PIR insulation installed above the roof structural sheathing board.
