Hi all,
I am looking for input on both brands of air and vapour barriers to use and also where to locate them. We are in climate zone 6 and are hoping to get as airtight as possible.
Our wall assembly is:
2 x 6 stud wall with R22 Rockwool Comfortbatts
exterior sheathing
2 layers of 3 inches Comfortboard 80 for a total of R24
1 inch strapping and air gap
Maibec wood siding
Our roof assembly is:
rafters filled with R22 Rockwool comfortbatts
roof sheathing
3 layers of 3 inches Comfortboard 80 for a total of R36
2nd layer of sheathing
metal roof
Thanks in advance,
Jackie
