Abstract:

A composite panel for use in the construction industry includes a core of foamed plastic material and a skin on at least one of its faces comprised of a two-ply material consisting of aluminum foil bonded to a mat of randomly oriented glass fibers into which the foam core has been expanded. The core material comprises the rection product of isocyanurate and polyester/polyether polyol with the isocyanurate in sufficient excess to form trimmer rings and to react with the polyol to form urethane linkages. Panels formed of the core material and the two-ply skins have excellent thermal insulation and fire retardant properties and the skins have excellent mechanical strength.
