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. 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.
