ledger board + exterior insulation + outtie door?
I was wondering if someone can help me figure out how to properly attach a ledger with fairly thick exterior insulation? I think this is a fairly niche situation and I’m having a hard time finding info. My house is post + beam and seems like the walls are built outside of the rim joist: the exposed timber framing rests on the rim/foundation, but drywall & foam insulation is outside the envelope of the foundation. Furthermore the patio door is an outtie and rests on an extended jamb.
The current ledgerboard seems to lagged through foam insulation (4″), drywall (1/2″) and layers of plywood (3″) totaling almost 7.5″. I watched Mike Geurtin’s video on brackets like (maine deck bracket). But 7.5″ seems a bit much for the brackets. I was thinking of cutting through the layers and bolting the ledge directly to the rim. But I’m concerned about door jamb. Would it be ok to have the extended door jamb rest on the deck (either on the decking or blocks on the joists?
Thanks for taking the time to read this, looking forward any and all advice.
