Soundproofing of a door

Mr. K. from Neuhofen (Germany) reports:

Problem: soundproofing of an interior door (in the cellar of an appartment building), of a home cinema and music room to protect the neighbours.

Solution: With our acustic panels soni COMPOSITE 32 mm and the application of additional sealing profiles between door leaf and door casing - as recommended by soniflex - we achieved a very good sound proofing of our interior door. Now I can enjoy the film in my home cinema without bothering my neighbours.
