Crawlspace Foundation-above grade part
Looking for some thought and opinions. . .
Building a house in WI. Footings need to be 48″ below grade and I want the crawl to be 3-4′ tall. I plan on sealing the crawl and it being climate controlled space. House construction will be conventional framing.
For the lower 4′ of the foundation, it will be poured or block, not sure yet. My question is in regards to the upper 3-4′ of foundation (the “crawl wall”, if you will). What is the best way to approach this?
1) Cap with PT sill and build 2×6 stud walls with OSB or PLY sheathing, insulate and poly the interior.
2) Same as above, but all PT including PT ply sheathing
3) Pour or build block wall up to full height – then how do I insulate? Aparently exposed foam on the walls in that area need to be covered by at least 1/2″ drywall – FG and poly do not.
4) Use ICF’s for all of it and then cover interior foam with ?
That crawl wall will be covered on the exterior with stone veneer or cultured stone veneer. If I use regular stone veneer, then the foundation will need a ledge of some kind – I suppose that if I go with the wood crawl wall, then I will have to cover with ice and water shield that wraps over the ledge?
Thanks for any insight you can offer or experience you can share.
