Sound Lock™ Double Door Seal Kits
Soundproof double doors with the Sound Lock™ Double Door Seal Kit. Double doors have even more air gaps than single doors, further increasing their need for a sealing solution. Whether these doors are in an office, school, or other, there's no better way to keep unwanted noise out of a room with double doors.
If your double door is not sealed between doors, you need an astragal seal.
