VENTILATED STANDING SEAM METAL ROOF INTERNALLY INSULATED (SMARTVAP)
A “cold roof” design continuously ventilated from ridge to eaves below the roof sheathing board. The SmartVap intelligent air barrier membrane above the ceiling forms a continuous air and vapour control layer 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.
