Helping the home of the newly installed broken bridge aluminum windows leak causes
1, due to the adjacent windows and doors of the building wall itself is flawed, resulting in the rain under the action of wind load through the wall directly into the room, especially in the external wall for the paste when the phenomenon is more common, because the gap between the brick often Fine cracks exist. This phenomenon due to seepage parts close to the doors and windows are often mistaken for doors and windows leaking.
