List of references
Specifies requirements for the composition, construction, dimensional tolerances, designation, and physical properties of two types of polyurethane (PUR) and polyisocyanurate (PIR) foam cored thermally insulating laminated board (roofboards) with auto adhesively bonded reinforcing facings and cores not less than 20 mm thick, for use in roofs under built up bituminized felt roofing materials. Coverage includes designation and marking. Also includes annexes, tables and diagrams.
