DCT-W13-1
LIGHTWEIGHT CLAD EXTERNALLY INSULATED TIMBER FRAME (XPS)
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.
