Hello, I've got a 1 1/2 story Cape Cod in Milwaukee Wisconsin, and I was hoping to get some input on how I can best insulate it. I plan on sealing off the knee walls with 2 in rigid foam, and foam spray, along with any light fixtures, electrical boxes, pipe chases, and anything else I can find that's open. My question to you is.....Should I use blown in insulation over the existing batting I have in my two crawlspaces on each side of the bedroom? if so, when I install soffit baffels, can I let the insulation touch against these, as it will be pretty close to the roof deck. How much R value should I put in the crawlspaces? I can also access the top attic which has batting just to the top of the joists. As you can see from the pictures, the outside walls in the attic crawlspace have no insulation at all. How should I insulate these? and how can I better insulate my knee walls? Please let me know if I'm missing anything, as I want to do this right! Thank you in advance ~Adam

Our 1926 house has a finished room in part of the attic that is completely uninsulated. It is miserable up there. We are starting the process of insulating it. We've just about finished sealing up the spaces between all the floor joists. There are a few things i'm not sure about, though. How can I get the fiberglass batts to stay in place on the knee walls? Should I tack at the top with a few staples, then cover it up with some rigid foam? I have decent access to the flat part of the room's ceiling, so I'll either do batts or blown in up there. I'm not sure what to do about the sloped part, though. The gap is only the thickness of the roof rafters and there are occasional nails sticking through from the roof. Should I block off the bottom of the sloped section with some rigid foam and try to fill the cavity with loose insulation? Or should I try to stuff some batts in there? Either way I'll be using some rafter vents - there is a dormer vent in the "upper" area above the attic room. Hope this all makes sense. Thanks for any help/suggestions!
