my cape cod is very poorly insulated... each year i add more and more to it. The back of the knee walls on the 2nd floor aren't insulated at all--that's a project to do before it gets hot again. I keep reading about air sealing just below the knee walls on the unfinished side-- blocking the conditioned air between the 2 floors from escaping into the unfinished portion of the lower attic.
In the front of my house, no problem--i can do this. In the backside of the house, the X style wood braces that keep the floor joists from flexing/bowing are right in the way. Is it worth it to put the air sealing rigid foam on the unfinished side and trying to seal off the couple of inches on top? Or how should i handle this?
