radiant barrier only?
hello, I am moving into a new to me house soon and there's a little crawlspace/attic thing that runs along the front wall of the upstairs, there are doors to get in in both upstairs bedrooms. It's convenient but there's absolutely no insulation in it. it's not even sealed properly, you can look in and see daylight at the bottom where it connects with the roof. I can seal that up with Great Stuff or something similar but what I'm wondering is since there's no insulation at all, I'm wondering if installing radiant barriers will be enough to make a difference. I could put fiberglass batting on the wall that is the bedroom wall. would sealing the gaps and putting in the radiant barrier spanning the bare 2x4's be enough to make a noticeable difference?
I have probably managed a horrible explanation of what I'm trying to do and I'm sorry for that, this is all new to me. This is a rental house, btw, and the owners are family and giving me a sweet deal on the rent so I don't think they'll be wanting to spend the money on insulation.
thanks so much for any help.
