Buenos noches y’all,
I’m about to order my first door (marvin).
To a simple 2×4 wall with 1/2″ sheathing and drywall I am adding a 3/8″ air space between the siding and felt paper and 1/2″ of wall to wall insulation to the interior.
Marvin’s standard jamb is 4+9/16″.
How much should I ask for as a jamb extension?
7/8″? or a tad more (that’s a skotch extra for you Minnesotans) because everything expands a little when you put it together?
