    Abstract - (Show below) - (Hide below)

    Describes requirements for laminated boards consisting of a core of rigid urethane foam bonded to two facings. Such are suitable as ceiling and wall linings where thermal insulation is required. The user should satisfy himself that the construction will meet building regulations, especially in relation to fire properties. Covers references, applications, construction, composition of foam core, permissible manufacturing deviations, physical property requirements, marking and sampling. The appendices include method of test for compressive strength, water vapour permeance, thermal conductance, dimensional stability at high and low temperature, stiffness in bending and burning properties of rigid urethane foam core and recommendations regarding its use and general notes for the end-user.
