Wall Assembly Climate Zone 3
Ready to finalize my wall assembly. I’m just not sure about this House Wrap layer. Would it be best where I have it now (see below) or have it between the XPS rigid foam and the slicker drainage mat?
1/2 inch gypsum
2×6 wood framing
Cavity insulation with blown-in cellulose (R-20)
1/2 inch OSB structural sheathing
House Wrap (as Air Barrier)
1 inch Rigid XPS Foam (R-5) (mainly to reduce thermal bridging)
Slicker drainage mat
LP Smart side panels and trim with insect screen and appropriate flashings.
I’ll keep studying the site…Thanks in advance
