Commercial metal roof externally insulated with a vapour barrier faced mineral fibre insulation blanket supported by a safety mesh. The full thickness of the insulation is maintained using structural spacers at each purlin. The ProctorGeo HC8 spacer mat installed below the roof sheet, and above the vapour permeable ProctorWrap HTS sarking, provides for drainage, ventilation and acoustic attenuation.

ProctorGeo HC EnkaVent Drainage Spacer Mat is a three dimensional shaped mesh of polyamide monofilaments, tangled and fused together.

ProctorWrap High Tensile-Roof (HT-S) is a medium weight highly durable medium duty vapour permeable roof underlay for use in tiled, slate and metal roof applications. ProctorWrap HTS-IT is supplied with double integrated tape.
