Abstract
An insulation stop for use in buildings, such as a dwelling, having truss type roof, and which is capable of confining any type of insulating material to the area directly above the ceiling, while providing maximum space between the roof rafters and the underside of the roof for full flow of ventilation, to thereby materially reduce the energy required for air conditioning the building, as well as the cost involved. The invention consists of a single sheet, preferably of fibrous material, or which could be composed of light weight metal or plastic capable of being bent and folded. A plurality of such items are utilized to form the insulation stop for a complete building with one such item associated with and disposed in part between adjacent roof rafters.
Claims4
An insulation stop comprising, in combination with two adjacent roof rafters, a rectangular sheet having a top edge and a bottom edge, said sheet having slots disposed parallel to said edges and extending inwardly from the ends thereof, said slots being in alignment with one another and terminating a substantial distance apart to form attaching tongues between end portions of said bottom edge and said slots, said tongues extending substantially perpendicular from the plane of the sheet in the same direction and being spaced apart a distance corresponding to the spacing between adjacent sides of adjacent ceiling joists against which said tongues abut and are secured, the part of said sheet disposed between said tongues constituting a vertical wall closing the opening between said joists, said sheet having a fold line extending between adjacent ends of said slots, said fold line and the slots, said top edge and the end portions disposed between the slots and top edge, combining to form a large flat panel disposed at an oblique angle to said upright wall and extending between said adjacent roof rafters and in an underlying relationship to bottom surfaces thereof, and means securing said panel to said bottom surfaces of the roof rafters to combine with said upright wall to form an insulation stop and with portions of the roof and said two roof rafters to provide a passage for the free circulation of air from the surrounding atmosphere between the roof and ceiling.
