Door Seal


To maintain privacy and the required sound transmission loss ratings with acoustic door sets (frame, door and seals), we offer acoustic seals to provide a barrier to airborne sound and help ensure that the acoustic performance provided by a door set which conforms to the specified rating for the wall or partition into
which it is installed.

Acoustic door seals effectively close the gaps for secure, soundproof doors that meet the necessary specifications - even the smallest gap around a door reduces its ability to shut out noise.

The range includes perimeter seals, door stop seals, bottom seals, spring-loaded bottom seals and special meeting stile seals for swing doors.
When applying any acoustic door seal, it’s important to consider any locking or latching requirements that may apply. Acoustica Projects has the expertise to ensure that the correct door seal systems perform safely and effectively to bring closure to your noise problem.
