Swimming pool or aquatic centre roof externally insulated with a continuous closed cell moisture resistant DCT XPS insulation board above a ProctorGeo Vap120 vapour retarder supported by purlins, a safety mesh, roof deck or strapping. The ProctorGeo HC9 drainage mat installed between the roof sheet, and above the vapour permeable ProctorWrap HTS sarking, provides for drainage and acoustic attenuation of rain noise. The continuous external moisture resistant insulation maintains the roof structure at indoor temperature which should be above dew point.
ProctorGeo HC9 Drainage Spacer Mat is a three dimensional shaped mesh of UV stabilized polypropylene monofilaments, tangled and fused together.
Enviroseal 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. Enviroseal ProctorWrap HTS-IT is supplied with double integrated tape.
DCT GA 300 is a closed cell high compressive strength, low moisture absorption extruded polystyrene (XPS) general application board for insulating roofs, walls and floors in commercial and residential applications.
ProctorGeo Vap120 is a light duty air and vapour control layer.
