Abstract:
1. A construction material comprising: a first sheet having a first fastening area on a top face of the sheet, and a further fastening area on a bottom face of the sheet, the first fastening area is located from substantially a top edge of the top face of the sheet to a bottom edge of the top face of the sheet, and the further fastening area is located from substantially the top edge of the bottom face of the sheet to the bottom edge of the bottom face of the sheet, wherein the first fastening area and the further fastening area are partially coated with an adhesive, the first fastening area and the further fastening area each comprising: at least two bonding regions, each bonding region extending from adjacent to the top edge to adjacent to the bottom edge, wherein adjacent bonding regions are separated from one another by at least one adhesive-free region, the adhesive-free region also extending from adjacent to the top edge to adjacent to the bottom edge and formed such that, in an operative state, a third fastening area on second, substantially similar sheet is bonded to the first fastening area by adhesion of at least one bonding region of the third fastening area to an adhesive-free region of the first fastening area wherein the material is at least one of air-tight, wind-proof, and water-tight, and wherein at least one of the at least two bonding regions is narrower than the at least one adhesive-free region.
