DCT-R10-2 EXTERNALLY INSULATED TIMBER DECK WARM ROOF (PIR)
A "warm roof" design protected by an exposed waterproof membrane, continuously insulated by a rigid PIR insulation installed above the roof structural sheathing board.
DCT-R10-1 INTERNALLY INSULATED VENTILATED TIMBER DECK COLD ROOF WITH AIR TIGHT CEILING (PIR)
A "cold roof" design protected by an exposed waterproof membrane, continuously ventilated from ridge to eaves below the roof structural sheathing board and insulated between and/or below the joists/rafters by a rigid thermoset DCT PIR insulation board, forming a continuous air and vapour control layer at the ceiling.
DCT-R05-4 FLAT CONCRETE IRMA ROOF WITH PEDESTALS AND PAVERS (PROCTORGEO IRMA)
Inverted Roof Membrane Assembly (IRMA) concrete roof with pavers on pedestals, insulated externally with a moisture resistant high compressive strength DCT GA300 XPS insulation that serves to protect the membrane from exposure and maintains the roof slab at a stable indoor temperature. A water resistant ProctorGeo IRMA geotextile installed above the insulation manages rainwater to minimise rainwater cooling below the insulation.
DCT-R09-3 EXTERNALLY INSULATED GREEN ROOF WITH RAINWATER STORAGE, DRAINAGE AND ROOT AERATION (DC20-R)
Green roof, externally insulated with a moisture resistant high compressive strength XPS insulation, located below the waterpoofing membrane barrier to maintain the roof slab at a stable indoor temperature. The insulation is weighted down by a green roof system which includes a combination of geotextile layers that offer rainwater storage, drainage, root aeration and protection of the waterproofing.
DCT-R04-2[R] TILED ROOF WITH CATHERDRAL CEILING BELOW RAFTERS (SMARTVAP)
Pitched tiled timber structure roof with a cathedral ceiling below the rafters. 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.
DCT-R02-3(R)RESIDENTIAL METAL ROOF WITH CATHEDRAL CEILING BELOW RAFTERS AND MEMBRANE BELOW BATTENS (SMARTVAP)
Residential timber structure metal roof with a cathedral ceiling below the rafters. The SmartVap intelligent air barrier membrane at the ceiling forms a continuous air and vapour control layer with ceiling insulation added above. The vapour permeable sarking is draped over the rafters, separated from the roof sheet by the roof battens providing for drainage of any moisture or condensate forming below the roof sheet. Suitable for ventilated and unventilated roofs.
