Abstract
A vapor retarder system includes a vapor retarder sheet. At least one and typically a plurality of parallel spaced-apart tie-straps are located adjacent an inner surface of the sheet, and the tie-strap extend across a width of the sheet and are connected to the sheet at multiple connection locations that are spaced from each other along a length of the tie strap. The sheet includes drape regions where the sheet is disconnected from the tie straps between successive connection locations. The tie-straps and drape regions ensure that the vapor retarder sheet is installed over roof purlins with the proper drape between the purlins to obtain the required insulation R-values. A fall-protection net or sheet can also be constructed and/or installed in the same manner.
