This British Standard specifies requirements for rigid polyisocyanurate (PIR) and polyurethane (PUR) cored laminated boards (roofboards) with auto-adhesively or separately bonded flexible and/or rigid facings, for use as roofboard thermal insulation under built-up bituminous roofing membranes. The standard also applies to product roofboards with one flexible and one rigid facing.
NOTE 1 Because of the changes introduced into this standard, products conforming to this standard also conform to BS EN 13165:2001 incorporating amendments 1 and 2.
NOTE 2 Additional information for the guidance of users, installers and designers is given in informative Annexes A, B, C, D and E to this standard.
