Insulating a walkout basement in Alaska

KelliSean | Posted in General Questions on

I have a 6 year old home with a partially finished basement. I have been in the home a year and would like the basement to feel warmer. The house is partially underground as we are on a sloped lot. The walls are block underground and wood framed above, with a concrete floor that I think is uninsulated.
The walls in the unfinished space have fiberglass batts and vapor barrier. Electrical is done what would be a good way to tackle this? Leave walls in place and foam or use thin sheets of foam behind walls? The walls are built about an inch from the block walls.

Thank you

    If the walls are not yet covered with gypsum drywall, I would throw away the fiberglass batts and hire a spray-foam contractor to install closed-cell spray polyurethane foam.

    I did get one quote for spray foam for the room that is 12 x 24 but it was a little over $3000 so I was hoping for a cheaper route. There is no drywall up.

    What part of AK? Rigid foam can be applied yourself, and has been discussed here. I think also has info on this.
