Abstract:
In the method of constructing an insulated roof or wall system which includes at least three consecutive, spaced, substantially parallel structural members having spaces therebetween and a longitudinal surface for receiving thereon a sheet of vapor barrier material for retaining insulation within said spaces, the steps comprising; applying said sheet of vapor barrier material across said at least three spaced structural members, applying a layer of compressible and recoverable insulation having a predetermined thickness which at least in part determines the R-value of the insulation located over the sheet of vapor barrier material, and applying a cover material over the layer of insulation, the improvement comprising the steps of:a) overlaying the longitudinal surfaces of said at least three spaced structural members with an untaut sheet of vapor barrier material having an untaut width sufficient to allow the formation therewith of an insulation cavity within said spaces between said structural members to a depth of drape sufficient such that when the insulation layer resides in the cavity a substantial portion of the insulation has a thickness approximately equal to the said predetermined thickness; b) overlaying the untaut sheet of vapor barrier material with a layer of said insulation; c) forming the insulation cavity to said depth of drape, wherein a portion of said insulation is located in said cavity; d) overlaying said insulation with a covering material; and e) forming a structurally integrated roof or wall system by securing said vapor barrier sheet, said insulation, and said covering material to each other and to said structural members, whereby a substantial portion of said insulation in said cavity has a thickness approximately equal to said predetermined thickness.
