A "cold roof" design continuously ventilated from ridge to eaves below the roof sheathing board with a rigid thermoset DCT PIR insulation board forming a continuous air and vapour control layer at the ceiling with further ceiling insulation added between the rafters. The ProctorGeo HC9 drainage mat installed directly below the standing seam roofing, and above the self-adhered vapour permeable Wraptite SA sarking, provides for drainage and acoustic attenuation of rain noise.

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 or condensate forming below the metal roof sheet.

A "warm roof" design continuously insulated by a rigid PIR insulation installed above the roof sheathing board. The ProctorGeo HC9 drainage mat installed directly below the standing seam roofing, and above the self-adhered vapour permeable Wraptite SA sarking, provides for drainage and acoustic attenuation of rain noise.

Commercial steel framed pitched metal roof with a suspended horizontal ceiling. The rigid thermoset PIR insulation board forms a continuous air and vapour control layer at the ceiling with further ceiling insulation added above. The vapour permeable sarking, separated from the roof sheet by a drainage batten provides drainage of any moisture or condensate forming below the roof sheet. Suitable for ventilated and unventilated roofs.

A lightweight clad steel frame wall insulated within the frame with a continuous closed cell high compressive strength DCTech XPS thermal break strip fixed between the cladding and the frame to form a drained and vented cavity. The frame and insulation are protected by a vapour permeable, air and water tight ProctorWrap sarking. The interior DCT PIR Silver insulation is mechanically fixed directly to the interior face of the frame and must be taped and sealed to form a continuous air and vapour control layer. As the thermal break strip and PIR insulation are both deemed combustible, this solution is never recommended for type A or B non-combustible wall construction.

Inverted Roof Membrane Assembly (IRMA) concrete roof, insulated externally with a moisture resistant high compressive strength XPS insulation that serves to protect the membrane from UV exposure and maintains the roof slab at a stable temperature. The insulation is weighted down by a stone ballast loaded above a drainage layer with integrate geotextile to manage drain rainwater above the insulation layer.
