Sealing insert for openings in walls in buildings

摘要

The insert consists of a frame which is made from U-sectioned profiles (4) and which is filtered inside an opening in a wall (3). The profile is fitted so that the open side of the U-profile faces the inside of the opening in the wall. A hollow, inflatable body (5) is mounted inside the U-profile around the frame. When the hollow body is inflated, its side presses against the sides of the opening and against sealing inserts which are mounted in the corners of the opening to round the corners. To further close the opening in the wall, a panel is mounted with screws against the side of the frame.
