Abstract: In a sound-deadened wall comprising wooden studs, each of which has a front edge and a back edge, a front wall panel is fastened to the front edges of the studs and a back wall panel is fastened to the back edges of the studs. Further, front spacers are positioned along the front edge of each stud, between the front edge of said stud and the front wall panel, so as to define air gaps between the front edge of said stud and the front wall panel, and back spacers are positioned along the back edge of each stud, between the back edge of said stud and the back wall panel, so as to define air gaps between the back edge of said stud and the back wall panel. Each wall panel has two expansive surfaces and the associated spacers are defined by elastomeric strips adhering to such wall panel, on the expansive face to face the associated edges of the studs, before such wall panel is fastened to the associated edges of the studs.

Abstract: An insulating structure comprises a board of insulating material having two major surfaces, two side edges and top and bottom edges, and facing sheets on each of the major surfaces, and a generally rectangular closure strip having two equal and integral side portions. One side portion is bonded to one of the facing sheets and extends over said facing sheet from the top edge to the bottom edge and inwardly a short distance from one of the side edges of the board. The other side portion extends outwardly away from the board a short distance from said side edge. A plurality of the insulating structures are positioned in abutting relationship to form an insulating envelope covering a wall or roof of a building.

Abstract: A method for continuously producing a rigid polymer foam in rolled form comprising (a) continuously conveying a carrier along a production line, (b) depositing on the carrier a foam-forming mixture, a regulating means being located on the production line to ensure deposition of only enough of the foam-forming mixture for production, after foaming and curing, of a rigid foam having a maximum thickness of less than 1 inch, (c) foaming and curing the deposited foam-forming mixture to produce a rigid foam, and (d) rolling the rigid foam.

Abstract: An exterior wall assembly comprising an outer weather-resistant layer, a heat insulating panel situated interiorly to the outer layer, a wall situated interiorly to the insulating panel, and a drainage track. The drainage track includes a clog-resistant drainage channel so that water collecting behind the insulating panel may drain from the assembly. The drainage track, in a preferred form, is extruded from PVC and defines a substantially L-shaped configuration in cross-section. An elongated, relatively tall flashing leg is provided for attachment of the drainage track to the wall such that all water-resistant material and insulation laps over the flashing leg to direct water into the drainage channel. Finish apertures are provided through a portion of the drainage track so that exterior finish such as, for example, stucco, will readily adhere and bond to the drainage track.

Abstract: A method for continuously manufacturing an insulation board by facing a foam-forming composition with one or two facing sheets to form a singly or doubly faced composite, at least one sheet comprising either a tough polymeric layer or a laminate of a tough polymeric layer with at least one other facing material, the tough polymeric layer of at least one sheet facing to the outside of the composite, and foaming and curing the faced foam-forming mixture to produce an insulation board having an exceptional hardness and puncture resistance.

Abstract: A process of producing an asphalt-impregnated fiberboard comprises the steps of forming an aqueous slurry of a fibrous material and asphalt, the solids content of the slurry being less than about 8 weight percent, mixing the slurry to uniformly distribute its components, dewatering the slurry to form a wet mat, pressing the wet mat to consolidate it, and drying the consolidated wet mat. Fiberboards made by the process can be employed as durable resilient expansion joints between various types of structural members.

Abstract: A method for continuously manufacturing a plastic foam reinforced by at least one fibrous material comprising continuously conveying a carrier along a production line, supplying on top of the carrier a foam-forming mixture and at least one continuously moving fibrous material, the fibrous material being non-expansible and having holes penetrable by the mixture, the mixture being supplied above both the fibrous material and the carrier or below the fibrous material and between the fibrous material and the carrier, passing the carrier, mixture and fibrous material between two spaced opposed constricting members which lie one above the other and form therebetween a metering gap for distributing the mixture over the carrier and fibrous material, and allowing the mixture after passing through the gap to freely expand and penetrate the holes of the fibrous material to form a reinforced plastic foam which has an exceptionally flat surface.

Foam boards having a highly uniform thickness are thereby continuously and expeditiously producible.
