phone jack box/cable jack box
« on: August 12, 2008, 11:00:58 PM »
Hi John,

Thanks for all your advice so far, and.... I have another question for you.

What to do for soundproofing by the phone jack box and cable box.  They both will require the same cutouts in the drywall as the electrical box.  I can put insulation behind them because they don't take up any room in the stud cavity, but I feel like I should do more.  The boxes are just a hollow shell so there is no back or sides to stick putty to.  I guess its just an extension piece that they attach to the front of the stud where the drywall goes.

Are there special foam gaskets for these too that I can install under the plate after drywalling?

Thanks again.

The builder put electrical boxes on the back of the cable/phone hollow extensions, so I can just use the putty in the same way as the electrical boxes.
