System for air sealing in building corners |
(57) The present invention relates to a system for air sealing of leaks (109) in building
corners (105) in a wall portion (100) made up by a framework (102). The system comprises
a cover element (1) comprising at least two flexible film portions (2) of an airtight
film with vapour retarder or vapour barrier properties, which are interconnected along
rim portions (6) by means of linear weld joints (7). The linear fold lines (8, 9)
are arranged in said film portions to allow folding of the cover element to form a
three-dimensional geometry consisting of three surfaces (A, B, C, a, b, c) which meet
at a point of intersection (P) and a diffusion and air sealing film (104) attached
to the wall portion. The three-dimensionally folded cover element is adapted to be
fastened to said diffusion and air sealing film in said building corners for air sealing
of said leeks.
