Basement Insulation question.

I have taken down the wood paneling in my basement and want to start insulating using Foam Boards. My walls are not levelName:  New 072.jpg

Should I cut the foam into three sections and apply to the wall or just stand it straight up and down?

thanks

Hi Keith and welcome to the forum,
You will want detail some insulation in the rim joist, the wood above the top of the foundation. A couple of points to consider:
1. Termite inspections may require you don't seal that area completely.
2. If you stuff it full of fiberglass or mineral wool without covering it, the mice will love you.
3. Any rigid foam you install may, depending upon local codes, require an ignition barrier, ie, cover it with drywall OR, use an approved foil faced rigid foam board.

Since you have extra space in the upper area of the wall where it will experience the greatest heat loss, I would consider filling that space with additional rigid insulation, or consider Roxul mineral wool as it is listed for direct application to the foundation walls.

Check your local codes to see what total r-value you will need.
