There is normally no need to use foam panels. Usually they are used on the exterior of the house on newer construction.

Regional difference here. I asked a couple contractors and they both said putting it on the inside of the wall is a good move... saw it in a couple different books on the subject as well. This is a more insulation = better region.

Sheeting is another 50/50 thing. Ask 2 contractors (as I did) and they'll give you opposite answers. Read through 4 books (did that too) and they'll split on it as well. It really seems to be one of those determine your house's needs parts of the job.

I did not do sheeting. My basement was like Chad's, very dry. My sump pump never, ever ran in that house. As a precaution, I did drylock the walls and decided I didn't need sheeting. I was told by our inspector to drylock the basement walls and not to put up sheeting.

Damn right. Ended up buying a couple too.
--- Quote from: Ed_McCarron ---You're New England, right? Whats the typical 'cold' winter temp? Not the 'gee, its chilly' cold, but those one or two cold snaps you get where its downright cold.
We get down around 10-15 in PA, I assume you get colder snaps?

The coldest parts of February get down below 0 at night, the holy crap cold here is -10 probably with wind chills in the -25 range. That's just an educated guess, though. I'm Canadian so I tend to wear jean shorts outside until it gets to around freezing.
--- Quote ---Reason I ask - theres no insulation at all on my basement walls (1920's house) and I see frost form when its cold enough...

I don't think I've seen frost but that might have more to do with ground temp than air temp, or maybe thickness of the foundation itself, or material. Yours wouldn't be poured concrete from 1920, would it?

We don't even have a pump. I've only had external water in the basement a couple times in six years and both were in extreme rain situations. One was raining so much the bottom of the chimney was leaking and still it was less than an inch in one corner.

Here is a local weather observatory's temperature chart for 2003 not too far from here... it gets a good picture of means. Of course extremes are way lower but not sustained for more than 3-4 days.

Thanks for the info guys. I really do need to get started. I have a couple of working games and a coouple of projects in my unheated garage. At least if I frame it out soon I can feel better about moving them down there. My insulation and wood estimates just shot through the roof though.
