Sealed doors for more comfort

Installing an automatic drop seal is always a good idea, because it noticeably increases living comfort. Its use offers reliable protection against noise and sounds, dust, dirt and unpleasant draughts.

The task of an auto drop seal

The task of an automatic drop seal is to ensure that the gap between the floor and the swing door is tightly closed. And it works like this: when the door is closed, the seal lowers automatically due to a release mechanism. The bottom gap between the floor and the door closes and noise, draughts and cold no longer have a chance to enter the room.

The good thing is that this process does not require any electricity, because the automatic door seal is activated and deactivated by a spring mechanism. This sophisticated technology also makes it possible to use it on uneven floors. The sealing profile adapts ideally to the floor conditions, regardless of whether it is uneven, sloping, concave or convex.
