Inverted Roof Membrane Assembly (IRMA) CLT roof, insulated externally with a moisture resistant high compressive strength XPS insulation that serves to protect the membrane from UV exposure and maintains the CLT roof at a stable temperature. The insulation is weighted down by a stone ballast loaded above a drainage layer with integrated geotextile to manage rainwater above the insulation layer. Required fall in roof can be provided either by the CLT or a cut to fall XPS insulation.

Pitched CLT roof structure externally insulated with a continuous high density non-combustible DCT Vulcanwool insulation board fitted below counter battens. The vapour permeable ProctorWrap sarking draped under roofing battens provides drainage of any moisture under the roof tiles.

Pitched CLT roof structure externally insulated with a continuous rigid DCT PIR insulation board fitted below counter battens. The vapour permeable ProctorWrap sarking draped under roofing battens provides drainage of any moisture under the roof tiles.

Pitched CLT roof structure insulated with a low density mineral fibre insulation fitted between timber counter battens. The vapour permeable ProctorWrap sarking draped under roofing battens provides drainage of any moisture under the roof tiles.

Pitched tiled timber structure roof with a horizontal ceiling. The SmartVap intelligent air barrier membrane above the ceiling forms a continuous air and vapour control layer with ceiling insulation above. The ProctorWrap vapour-permeable sarking, draped under the tile battens provides drainage of any moisture or condensate forming below the roof sheet. Suitable for ventilated and unventilated roofs.

Pitched CLT roof structure externally insulated with a continuous high-density non-combustible DCT Vulcanwool insulation board fitted below counter battens. The vapour permeable ProctorWrap sarking draped under roofing battens provides drainage of any moisture or condensate forming below the metal roof sheet.
