Determines requirements for rigid polyisocyanurate (PIR) and polyurethane (PUR) cored laminated insulation boards with auto-adhesively and separately bonded flexible and/or rigid facings, for use as thermal insulation for wall cavities.

This British Standard specifies requirements for rigid polyisocyanurate (PIR) and polyurethane (PUR) cored laminated insulation boards with auto-adhesively and separately bonded flexible and/or rigid facings, for use as thermal insulation for wall cavities. It also applies to products with one flexible facing and one rigid facing.

NOTE Additional information for the guidance of users, installers and designers is given in informative Annexes A, B, C and D to this standard.
