Reducing transmission of sound through doorways

Reducing transmission of sound through doorways
November 14, 2016

The CS SoundStop cavity slider has been tested by Acoustic Testing Services and is supplied complete with a specialised acoustic door panel when an acoustic rating above STC 31 is required. Seals are fitted to the bottom and back edge of the door and the jambs, making it suitable for boardrooms, meeting rooms or any other area requiring a level of privacy. They are commonly specified in hotels, auditoriums, television studios and function rooms.

In most homes, where acoustic dampening is desired but not critical, such as bathrooms and media rooms, there are ways to improve on the sound transmission of a standard cavity slider.

A solid core door is recommended as a better option than hollow core. For large doors, or just for something a bit different, opt for a glazed aluminium door like the NewYorker from the CS DoorLeaves range. Available in a wide range of configurations, colours and glass types. As well as providing a good level of sound reduction compared to hollow core doors, they also have the advantage of being able to be made oversized up to 3m high x 3m wide.

Take floor coverings into consideration when purchasing your cavity slider. Standard clearance under the door is 25mm, which allows for carpet and underlay through the doorway. If you have timber or polished concrete floors, this can be taken into consideration at time of order so there isn’t a large gap under the door. Brush seals can also be added to the jambs and bottom of the door to reduce the standard gap.

Remove the added annoyance of slamming doors and ensure your cavity slider door closes quietly and smoothly every time by specifying a CS SofStop. The soft close mechanism brings the door gently to a controlled close, smoothly and quietly every time. It is fully serviceable, and suitable for doors up to 80kg, making it a must-have on frequently used doors in family homes.
