i will be finishng the basement soon and need to start thinking how i plan on insulating the foundation walls... normally i would go with gluing 3/4"-1" rigid inslation to the walls and then studding over them and another layer of fiberglass batt before sheetrocking...

but i have been watching alot of HGTV and it seems like they are starting to move toward spray foam insulation. i looked online for a DIY kit and they seem pretty expensive. wondering if any of the aziners had any experience with this stuff???

TIA

I have never used it, but i think that might be a job for the preofessional. They will prob have better equipment to make it easier to apply w/o any of the mess.

if a DIY kit is running $600, im thinking hiring a pro to come and do it will easily be a 1-1.5k job... i may go with ol faithful on the rigid stuff if that is the case... hmmm ...

any others?

your not going to see it in years so just go with regular insulation, and if you nee to repair or happen to replace a certain spot, you can just go to home depot and replace yourself

It is something i would pay a professional to do. When i build my home in the near future it is one of the very few things i will pay someone to do.

why not go with the rolls and a vapor barrier? How long are you planning on staying there?

and mudding drywall.

Nope, i will do that. I have gotten very proficient with it. Digging the foundation, HVAC are really the only 2 things i wont do. I will do every thing else myself (between friends in the trade and myself we can do plumbing and electrical) building will be a snap.

maybe another few years... def not my forever house... so that is why i was thinking about going the cheaper route...

i still can't get my joints perfect yet when i mudd... i find myself sanding alot and just wasting the spackle...

Go with just fiberglass insulation. No need to do rigid and fiberglass.

dallison

don't spend the extra money.

i thought the rigid acts as a vapor barrier... or do i just stud the walls directly on the concrete foundation walls and get the fiberglass special for the basement walls...

dallison

Do you need to frame your basement before adding the drywall? I would think so but not too sure. If it has to be framed, i would use the rolls and vapor barrier. I thought the barrier was the thicker plastic that you stapled up?

And then the drywall would go up. I am not sure of the proper way, but i'm not sure about any area below ground level, if it is below ground level.

Installation
1) Vapor barrier (6mil poly is fine) directly against foundation
2) Kraft-faced insulation with paper facing sheetrock
3) Sheetrock

If you have water issues you can also paint Dry-lock on the foundation walls prior to the vapor barrier.

I used furring strips and masonry nails to attach it.

I would not invest in foam insulation for a basement finish. Yes, the foam gives you a better R-value, but it's a basement and will ALWAYS be cold. Save the money (like others said), spend it on something else.
