Commercial metal roof externally insulated with DCT VulcanWool and internal ProctorPassive SmartVap air and vapour retarder, supported by a safety mesh. The full thickness of the insulation is maintained using structural spacers at each purlin. The ProctorVent VB20 and the ProctorGeo HC20 spacer mat installed below the roof sheet, and above the Class 4 vapour permeable ProctorWrap HTS sarking, provides for drainage, ventilation, and acoustic attenuation, meeting the NCC 2022 deemed to satisfy 20mm requirement for a ventilated roof space.

The ProctorVent VB20 Vented Batten is a Polypropylene 20mm Ventilation & Drainage Batten, designed to facilitate passive airflow in the roof void, reducing the risk of moisture build up and condensation.

ProctorGeo HC20 EnkaVent Drainage Spacer Mat is a 20mm thickness, 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.

DCT VulcanWool is a non-combustible high-density mineral rock fibre stonewool insulation for use as external grade insulation with water shedding characteristics, designed for use in ventilated rainscreen facades and other thermal and acoustic walls, roof, floor and ceiling applications in residential and commercial buildings.

ProctorPassive SmartVap is a light duty air barrier and variable vapour diffusion vapour control membrane.
