Last week after we put up the first floor exterior walls, Warren finished the interior wall framing, including the double stud wall and the structural wall that separates south-facing living spaces from the north-facing support spaces. He also tacked a few second floor trusses into place.
This weekend we finished installing all the second floor trusses and the second floor decking. We even got a chance to put up a few of the external sheathing ZIP panels.
If you’re not familiar with ZIP panels, they are plywood panels with a special external coating (the green layer). This coating acts as our moisture and vapor barrier when the seams between the panels are taped with ZIP tape. Using the ZIP panels means we don’t need house wrap or felt and will make our exterior air sealing much easier.
