Thanks for the suggestions guys.
I was actually reading up on that site a little earlier today truckncycle.
Larryrose11, its great to hear your heating bill is that low! My goal is to keep utilities under $100/mo average.
I had planned on sealing up the attic, although I haven't thought as much about that yet. It sounds simple enough. Can you recommend any specific product to use as far as expanding foam? I know there is Great Stuff, but thats about all I know of. I definitly plan on using cellulose instead of fiberglass. Just the thought of installing blown in fiberglass makes me itchy.
I'm not sure what I have as far as trusses go. I can pretty much bet its no energy heel though. The house was built in 1886. I'll have to take a look and see what can be done. How far in did you go with the polyiso insulation?
