A system for air sealing of leaks in building corners in a wall portion made up by a framework, including a cover element with two overlapping and plane flexible film portions, which are connected to each other along a first edge portion. The film portions include linear folding lines to enable unfolding of the cover element for forming a three-dimensional geometry including a main surface and a collar which projects from the main surface and is formed integrally therewith and which corresponds to three sides of the beam portion. |
