Disturbed night last night, so glad I got the cable into the breaker panel when I had a clearer head than I do now. Maybe today I'll just get busy trimming the last few panels to size. I'm really keen to get this one room finished - it will be a huge morale booster after all the setbacks and problems I've had in there.
I really wanted to put some sound blocking material behind the drywall but it turns out the stuff costs nearly $400 for a roll with shipping extra. I'd need three rolls for this one room, and there's no point doing this room unless I'm going to a bunch of other rooms as well. I really want to deaden the road noise, but don't know whether I really want to add that much to the overall renovation budget. Of course the eternal question is one of how far around the house I'd really need to go - obviously I want to kill the road noise as much as possible but don't want to spend loads of money blocking sound where it's not necessary but neither do I want to spend thousands on blocking only to find the whole lot is compromised because I missed a patch.
Maybe I'll just get busy with a tape measure and figure out just how much of this stuff I'm going to want, and make a one-time decision based on the total cost. It would be really cool to dull the noise, some of the trucks that go by are really loud.
