Top plate sealing? (ADA)
We plan on using Conservation Technology EPDM gaskets between the slab and (bottom) sill plate. And then some form of gaskets to create the airtight drywall approach (either the ones from conservation technolgy or Denarco).
What I am still a little unclear about is what if any seal is needed at the top plate(s)? The house will have a double 2×6 top plate. I have looked at a few different diagrams about ADA and weather sealing and for some reason I am still confused.
I found this diagram from an older post by John Brooks (hope you don’t mind me using it):
