Hello everyone,
In 2019, our garage was completed. A 6m wide Hörmann garage door was installed. The upper fixed frame was attached to the inner concrete lintel with steel brackets (see photos).
Between the frame and the front stainless steel lintel, a kind of compressible sealing tape was applied to seal the gap present there. When closing the door, this sealing tape is pressed together slightly, especially in the middle of the door, because the door pushes the frame slightly outward. When opening the door, however, the sealing tape does not relax sufficiently, so a gap forms between the frame and the stainless steel lintel.
Currently, it appears that even in the closed state there is a certain gap through which air constantly drafts and, depending on the weather, causes corresponding (moisture) problems.
The garage door installer normally fastens this frame with screws to the front lintel. Since ours is made of stainless steel and is therefore difficult to drill, he resorted to the Hörmann fastening brackets. In his opinion, this gap could now be sealed with silicone. I am not sure whether silicone is the best choice here.
In my opinion, the challenge is that the gap regularly "moves." Is there a special solution for sealing such a flexible gap? What do you recommend in this situation?
