DCT-R50-1
SWIMMING POOL ROOF EXTERNALLY INSULATED BY RIGID XPS INSULATION BOARD
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.
