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