How many Iso chips and furrings do I need
« on: October 23, 2004, 07:18:03 PM »
I have a room 28x15x10 (L x W x H).  I am going to place Iso chips, DWFC along with 5/8" drywall,vinyl barrier and another 1/2" drywall (sandwich together).  Aside from the wall, I will also do the same setup for the ceiling.  Taking all that into consideration how many ISO chips to i need, how far apart does the furrings have to be to evenly distribute the weight of the wall and ceiling?

Depending on the weight, the rule of thumb is 1sound clips for every 4 sq. ft of ceiling or wall.  We recommend furring track to be installed every 16" on the ceiling and three rows on the walls with vibration pads supporting the drywall every 18" or so on the floor.
