METAL ROOF OVER AN INSULATION BLANKET AND RIGID XPS THERMAL BREAKS (HC9 SPACER MAT)

Pitched metal cathedral roof externally insulated with a continuous vapour and air retarder faced mineral fibre insulation blanket supported by a safety mesh or strapping. The full thickness of the insulation is maintained using a rigid DCT XPS thermal break at each purlin. 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.
