This British Standard specifies requirements for polyisocyanurate (PIR) and polyurethane (PUR) cored thermally insulated laminated boards (roofboards) with auto-adhesively or separately bonded flexible and/or rigid facings, for use in roofs under non-bituminous single-ply roofing membranes. This specification is also applicable to roofboards with OSB or plywood facings bonded in place after the initial product has been created (see Clause 4).
