Insulating above grade basement blocks

[buckslayerII]

How do you guys go about insulating the inside of basement blocks that are above grade. There's really only about 1-1.5, but I was thinking about doing the first 3-4 to try to keep the floors warmer since there's no heat in the basement. My current thought is to just glue on some of that blue-board insulation. This is in the storage part of the basement. The soon to be completed finished part already has studs with fiberglass.

Thanks

Use "R-board" instead of the "blue board".

R-board - OK - help me out here. If I go into Lowes are they gonna know what that is?

Click on residential, there is a list of locations in Michigan. For what it is worth, I live in a town of about 1,500 people, our local lumber yard carries it. I would assume Lowes carries it, however, I couldn't find it on their website. I only suggested it because of the insulating characteristics are much better.

Maybe this will work.... 1.5" has an R-value of 9.0. I used 3/4", I made a hude difference...

:) Thanks for trying to post it. I checked it out and will see what I can find around here.

It looks like you are going to install it on the inside of the basement, not the exterior? If that is the case you can save a lot of money by going to your local roofing supply (not a mega box, a real supply house) and buy "Isoboard".
It's the same insulation, (polyisocyanurate) as the R-Board, but with a different facer, fiberglass laminated with asphalt. I don't know what area you are in, but a 4x8x 1.5" isoboard is running $18.50-$19.50 in southern MI. A bit more north of Midland due to frieght costs.

Spray Foam is the only way to go. Seals the house air tight. See if there is a person in your area that does this. Well worth the money..

[buckslayerII]

ESOX - you are correct - on the inside of the blocks. I actually talked to my local R-Board retailer and she said that it's not intended to be used on the inside where it'll be exposed. I'll check out the Isoboard, which I think is what she suggested (it's written down).

Hawkman - does the spray foam stick to a bare block wall? I would think it's kinda messy. This isn't a new build, I wanna just add some insulation to the top portion (above grade) of my existing basement walls.

Thanks guys.

Not bad at all, very control spray. You will have to move items away from the walls and the guy should put down paper to stop any little mess. There very little running, dries quickly. I have the name and number of the guy that did mine and a few other friends. Yes mine was a new built, but talking to him, existing just take a little longer.
