Usually doors have a frame made of two components called loom and counter loom. This two components are never put together one against the other but there is always space between the two pieces. Through this space, the air and the noise pass, this empty space is also dangerous because the burglar can use a screwdriver or a crowbar as a lift.
Among the two components, just the counter loom, or the external one, is anchored to the wall. The frame, that is the visible part is just screwed with small screws of 6 to 8 mm to the counter loom. If you think about all the bolts that leaks of a sheet door and are only attached to the frame, you can understand that the whole security is entrusted to those small screws that unify the frame to the counter loom.
The screws used to fix the frame to the counter loom give the possibility to adjust the shutter position later on, but those same screws are the cause of the problem. In fact every time that you close the door, this hit the frame and produce vibrations that in time let the frame position change. The missing alignment between shutter and frame let the air and noises pass and then it needs adjustments.
