Calling all home improvement gurus and energy efficiency wizards--help me figure out how to better insulate my attic! I've read through a bunch of information on energystar.gov and other websites about insulating attics, but the more I read the more confused I get about how to do this, because I have the world's weirdest attic. HELP. [more inside]

We just had an energy audit done for our 104 year old house and 3/4 of the heat loss was coming from the uninsulated walls. I was advised to get cellulose insulation. I've heard bad things about blowing insulation into old houses like mine, but the auditor said it would be densely packed and not be a problem. I've been reading up and haven't been able to find any definitive answers. Is it okay to have cellulose insulation blown in to my old house if it is densely packed?

Related back to this question, we are finally pulling the trigger on a new furnace, hoping to get the work done before a state rebate program for such purchases expires. We have gotten several good bids, and are taking more, but the best one came from a guy who would also fix our insulation problem- for $7000. We're a little daunted. [more inside]

How do I insulate my crawlspace? I'm thinking about next winter, now that I've barely survived this past one in the US Northeast. My house doesn't have a basement: it's built on concrete piers with a 1-2.5 foot crawlspace between the ground and the first floor. What would be the best way to insulate in this situation?

How can I insulate a sash-weight window in a 1900 house? (I wish titles showed up on the main page so they didn't repeat the question....) Seems like you kind of have to leave a big hole there for the weight. But a lot of cold air is getting in there. I'd rather keep the weights if I could.
