Foundation insulation details
I am hoping to meet with my foundation contractor in the near future and want to make sure I am as close as possible to having my ducks in a row. Can you guys take a look at the insulation details below and see if I am on the right track? An explanation of my plan:
– As shown in the first attached drawing, the north, west, and south walls of the house will include a brick ledge to provide support for ~5″ of foam on the exterior of the house. I am planning to ask my contractor to form this ledge above grade, 1′ below the top of the foundation wall, and form it with a flat face that continues down to just below grade. Foundation insulation on these walls will be on the interior. Exterior of foundation will be waterproofed, which is not labeled in drawings.
-There is an attached garage on the east side of the house. I plan to insulate the east foundation wall on the exterior, and have foam continuous from footing to top plate on this wall, coming up between the foundation wall and the garage slab.
So…how many ways am I screwing up? Thanks for the help!
