SOPRA-ISO is a rigid polyisocyanurate thermal insulation panel for use in approved multi-ply membrane and flashing assemblies. SOPRA-ISO is composed of closed cell polyisocyanurate foam bonded to fiber reinforced/organic mat facers on the top and underside.
Prior to installation, ensure all SOPRA-ISO panels have not been subject to moisture. Place SOPRA-ISO in an offset or staggered pattern to ensure board joints are not overlapping in multilayer assemblies. Apply to approved substrate via DUOTACK adhesive or hot asphalt following manufacturer specifications. SOPRA-ISO may also be mechanically fastened to approved substrates. Refer to the SOPREMA SBS Roofing Manual for additional application guidelines.
