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.

Timber frame wall insulated extremally by a high compressive strength DCT XPS insulation made water and air tight by the self-adhered vapour permeable ProctorPassive Wraptite SA and protected by a lightweight cladding on battens. Additional insulation within the frame would only be considered having assessed condensation risk.

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 Vulcanwool stone mineral fibre insulation, protected by a lightweight cladding on battens. 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 assessed condensation risk.
