sound transmitting between floors
« on: February 14, 2005, 05:02:30 PM »
We are building a multi family in chicago.  Our question is what is the best way to stop sound between units?

The floor system is constructed with 18" open web trusses, with 2 layers of 5/8" drywall on the ceiling below (Unit #1) and 3/4" T&G plywood subfloor on the top (Unit #2).  We are planning to install a finish Hardwood floor throughout, what is the best way to stop the sound from transmitting through the hardwood (unit #2) to the unit below? (unit #1)  What products can be installed between the plywood subfloor and the finish floor to stop this transmission?

Hello Mr. Mangan.
You will want to use material which decouples between the plywood and finish flooring. Also, include a barrier material
Please consider the thickness of the soundproofing materials. Because, the materials may effect the doors ability to close.

Thank you for your question?
