Automatic door bottoms

Automatic door bottoms perfectly close the gap between the door and the floor, thus creating a strong, reliable barrier to sound, air and dust infiltration.
The pressure exerted by the seal on the floor is the same across the entire door width.
The seal is dropped only when the door is in the closed position.
The door bottom seals used by the Door Design Lab are manufactured by Comaglio (Italy).
During the installation, the seal is to be fully mortised into a groove cut out in the door's bottom rail.
It's hidden and doesn't affect the appearance of the door.
After installation, the door bottom becomes an integral part of the door.
