I hired this contractor to build my dedicated home theater room. The room is 13' x 19' in the basement storage area. Three of the four walls are cement walls. I'm installing the three B&W 8.2s, four 7.3s and two subwoofers in the room. Here is the dilemma: I specifically executed a contract with the contractor to install Roxul in all of the walls to ensure I achieve a high STC rating. The contractor made a unilateral decision to install Roxul only in the rear wall (non-concrete) and the rest including the ceiling with either JM R38 or R19 or a combination of both in some areas (think the ceiling). I contacted JM to find out the STC rating and they responded that they don't have a rating on their products. The contractor had agreed to do a test of sound proofing the room with speakers before installing the drywall but didn't. I took it the liberty of placing two speakers in the room and could hear the sound all the way up to the third floor of my bedroom. I sent an email raising concern over the sound and asked that he make corrective action if necessary (since I am relying on his expertise as a contractor). He has since refused to respond to my emails and his workers are continuing with his project manager only saying that I heard sound because the entry door was detached. I've sent my second deposit to him (which brings the payment to 80% of the total cost) but can place a stop payment tomorrow. Am I over reacting or would R38/R19 compensate for adequately sound proofing the room if the door was detached? Any ideas on what I should do?
