Abstract
A fibreboard, insulating, wall panel includes an integral air and vapor barrier of metal foil or metallized plastic film adhered to one surface of the panel. Panels are attached to a stud wall frame. Abutting panel joints are taped to provide a continuance vapor barrier. Increased thermal and acoustic insulation as well as structural integrity of the barrier is provided by the panel.
Claims15
A composite insulating and vapour barrier building panel adapted for use in stud wall building construction, consisting of a first semi-rigid flat structural insulation component, selected from the group comprising a low density and a medium density fiberboard, and a second laminar barrier component integral with said first component, the second component being substantially flat and substantially impervious to atmospheric vapour and air penetration, wherein the second component is selected from the group comprising metallic foil, metalized thermoplastic film and a composite of layered thermoplastic film and metallic foil.
A stud wall building construction having a plurality of insulating, vapour barrier panels, with adjoining panels joined by a vapour impervious seal, the panels comprising a first semi-rigid structural insulation component selected from the group comprising a low density and a medium density fiberboard, and a second substantially flat laminar vapour barrier component integral with said first component, the second component being selected from the group comprising metallic foil, metalized thermoplastic film, or a composite of layered thermoplastic film and metallic foil.
A composite insulating and vapour barrier building panel consisting of a low density fiberboard panel with a continuous flat effective air and vapour barrier integral with one face of the fiberboard panel, the barrier comprising a continuous layer of kraft paper adjacent the fiberboard panel and a continuous layer of aluminum foil adjacent the layer of kraft paper.
A composite insulating and vapour barrier building panel consisting of a low density fiberboard panel with a continuous flat effective air and vapour barrier integral with one face of the fiberboard panel, the barrier comprising a continuous layer of polyethylene film adjacent the fiberboard panel and a continuous layer of aluminum foil adjacent the layer of polyethylene film.
A composite insulating and vapour barrier building panel consisting of a low density fiberboard panel with a continuous flat effective air and vapour barrier integral with one face of the fiberboard panel, the barrier comprising a continuous layer of kraft paper adjacent the fiberboard panel, a continuous layer of polyethylene film adjacent the layer of kraft paper and a continuous layer of aluminum foil adjacent the layer of polyethylene film.
A composite insulating and vapour barrier building panel consisting of a low density fiberboard panel with a continuous flat aluminum foil layer integral with one face of the fiberboard panel to provide an effective air and vapour barrier.
