Abstract:
1. A system for airtight sealing of leaks, comprising: at least one cover element, each of the at least one cover elements are configured to be disposed in a folded state configuration and include two overlapping and planar flexible film portions having substantially the same size, the film portions are being connected to each other along edge portions; linear folding lines being arranged in said film portions of each cover element, a first of the linear folding lines extends an entire longitudinal length of each planar flexible film portion from a first end to a second end, a first of the two overlapping and planar flexible film portions is symmetrical with respect to a second of the two overlapping and flexible film portions about the first linear folding line, wherein the linear folding lines to enable the at least one cover element to be changed from the folded state configuration to an unfolded state configuration, so as to form a three-dimensional geometry including a main surface and a collar having three sides, each of the three sides of the collar are configured to contact and project from the main surface, are formed integrally therewith, and are configured to correspond to three sides of a beam portion; and a diffusion and airsealing film configured to stretch over a wall portion and configured to extend beyond an outer perimeter of each side of the main surface of the at least one cover element along the wall portion, wherein the unfolded cover element is configured to be attached to said diffusion and airsealing film at an intersection between the cover element and the diffusion and airsealing film for airtight sealing of said leaks.
