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 inorganic coated glass 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 multi-layer 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.
