Rigid composite insulating partitions - with a conventional plaster surface tied through a foam polyurethane core to a corrugated metal sheet

摘要

Composite, self-supporting sheet panels having an insulating core of e.g. polyurethane foam are covered internally by a corrugated metal sheet and on the outer face by a layer of conventional wall finish material, e.g. plaster. Pref. the plaster is keyed to the foam surface by undercut grooves. Opt. the plaster surface is internally reinforced with a metal grid and/or tied to the opposite face by rods of non-conductive material, e.g. plastic studs. Panels may be coupled back to back, with the corrugated face channels aligned to provide internal ducts for wiring, plumbing etc.
