Hi Fellas,
New to this forum. I have been using the search bar to find an answer but cannot. I am not a Timber framer but intend on having one built in the next 12-18 months. Very interested in using a sip "pwf" foundation which has either 2x8 or 2x10 12in oc in the wall. It's made by Enercept. Anyone have experience with this type of foundation, as far as structurally sound regarding timber frames. Also looking into icf and superior walls. Just like the concept of being able to do the sip foundation myself, plus the high r factor.
