QuietRock Sound Proof Drywall

If you're renovating and considering putting in a home theatre, you may want to think about soundproofing the area. A quality soundproofing job will both prevent outside noises from entering your listening room/theatre and, conversely, give you the freedom to listen to whatever you like without having to disturb your house mates. Here's a drywall option, called QuietRock, that claims to be able to deliver that level of soundproofing. From the site:

• A single layer of QR-530 is equivalent to 8 layers of standard drywall (acoustically)
• QR-525 requires no power saw
• QR-545 is the only THX Certified soundproofing solution in the world
• 10x more reliable than resilient channel with no resilient channel liability risks
• Use like standard drywall (installs without special training)
• Fire rated. Environmentally friendly. Lab tested. Available in X, anti-mold, greenboard, blueboard, high impact and others
