An exposed single skin masonry wall such as a concrete tilt slab internally insulated with non-combustible DCT VulcanWool stonewool insulation separated from the masonry by a drained and/or ventilated cavity. The ProctorPassive SmartVap must be taped and sealed to form a continuous air and vapour control layer to reduce internal moisture vapour from reaching and condensing on the masonry. This solution is a rarely used compromise where external insulation is not an option. This solution is a high risk strategy that relies on the perfect installation of the internal control layer and the effectiveness of the drainage cavity. Continuous mechanical ventilation to manage indoor moisture loads will be required in most climates. An independent hygrothermal calculation in accordance with AIRAH DA07 must prove suitability.

Timber frame wall with a rigid sheathing board made water and air tight by the self-adhered vapour permeable ProctorPassive Wraptite SA, externally insulated with a non-combustible DCT VulcanWool stonewool insulation, protected by a rainscreen cladding supported by the Nvelope engineered helping hand sub-framing system. The insulation is mechanically fixed to the sheathing board with minimal thermal bridging, to form a continuous external insulation layer. Additional insulation within the frame would only be considered having assesed condensation risk.

Timber framed brick veneer wall, insulated within the frame and protected by a vapour permeable, air & water tight ProctorWrap sarking fixed to the outside of the frame.

Standing seam cladding on a thermally broken timber framed wall, insulated within the frame and protected by a vapour permeable, air & water tight ProctorWrap sarking fixed to the outside of the frame with a vented and drained cavity. The SmartVap intelligent air barrier membrane installed to the inside of the timber frame forms a continuous air and vapour control layer and is best fixed behind a batten to form a service cavity behind the plasterboard.
