Stained glass in interior door
« on: December 07, 2006, 06:46:54 AM »

I'm getting a second floor office in a commercial building divided into three rooms for two counselling offices and a waiting room - all fully walled and doored The rooms are in a row, and the last room is at the end of a corridor that passes by the other two rooms. The concern is that confidential discussions in the last room will be heard by other people.

One wall is an outside wall - no problem. Two walls connect to adjacent offices in the building on either side. Nothing much can be done without pulling the walls down and retrofitting, but it's probably not a big problem, since the other offices are anonymous people. The main concern is the common wall.

There is a possibility that sound will travel over transom/ductwork area into the other rooms.

The common wall will not be too bad, since it will have 8' high particle board cupboards against it.

The door to the corridor will be solid core door (landord agreed not to use hollow core when renovating the space) However, because of the length of the corridor - about 26 feet - it's desirable to place a stained glass panel in the upper part of the door to provide a better look and feel. To what extent will this cause additional leakage of sound through the door? I think it's probably ok, since the sound would get into the corridor and have to then bounce back into the other rooms. DOR - is the door in question, not a short 30" section of corridor wall extends into the room

Armadillo,

There are various methods and systems to treat a common wall.  If you're dealing primarily with voices (no music) then the simplest method is to install 2 layers of Mass Loaded Vinyl (MLV) barrier with adhesive backing directly over the existing drywall then finishing it with a 5/8" fire-rated sheetrock.  Make sure you tape the seams of the vinyl and apply acoustical caulk around the perimeter of the MLV and along the seams of the sheetrock.

You can further reduce the sound by installing a second layer of sheetrock with Green Glue sandwiched in between the two sheets.

Take a look at the MLV product description and Green Glue at the following pages:

http://www.soundproofing.org/brochures/mass_loaded_vinyl.htm

http://www.soundproofing.org/sales/GreenGlue.htm

An alternate system would make use of sound clips (SSP Clips), hat channel (DWFC), and Green Glue sandwiched between two layers of drywall.

If you soundproof the room in question then the sound transmitted through the stained glass may be insignificant.

Call us if you have any questions 888-942-7723.

Armadillo:

What kind of ceilings do you have?  If my suspicion is correct, your walls won't be the weak link.  More than likely, the walls are framed with steel studs and are fairly resilient.  If you have a suspended acoustical tile ceiling, that is what you need to worry about.
