Can you improve suspended ceiling ?
« on: August 03, 2006, 02:44:27 AM »
I have a video editing suite in a typical office building with a suspended ceiling system. The back wall of the suite is a simple wall that goes up to the suspended ceiling, but not to the deck above. There are no sound conditioning materials used at all.

We would like to keep more of the sound within the edit suite and to keep it from spilling into the adjoining offices. Unfortunately, we will only be in this space for another year or two and I don't want to invest in a complete double wall rebuild of the edit suite.

Can you suggest any material that we could lay on top of the suspended ceiling to either absorb sound of to help keep the sound from passing through  ?

Hello stephens557,



Without building the walls up to the deck above you will not be able to completely keep all sound from "spilling into the adjoining offices".  Since you will only be in the space for a while, try the following:

Get some MLV (1/8" thick, weighs 1Lb/ft2) and cut it to fit the suspended ceiling tiles.  Lay MLV on top of ceiling tiles (you may need to add support wires to carry added weight).  Then lay strips of bonded cotton insulation across the entire ceiling on top of tiles.  This material absorbs and blocks sound.  For specs of bonded cotton see

This solution has been used succesfully in situations like yours.
