I am in nanaimo and will be putting on 2" 'Powerwool' pretty soon.. apparently rock-wool cant produce lately... I guess the bugscreen and flashing at the base of the wall has to be wider to accommodate?
I use a custom L flashing on the bottom that nails to the front of the rainscreens and faces the house. Just a standard 3/4 inch bug screen for the tops of the windows. Again, any bugscreen details can be added to the OUTSIDE of the strapping and be facing inward. It's kind of hard to nail metal to insulation
On this particular house. The base metal you're looking it was actually capping over an insulated foundation. So there was no void underneath, Normally you will be build 3 inches off the envelope and the bottom of the Rockwool would be exposed
Depends on the size of the wall and the thickness of Rockwool you are using. You're obviously going to want to penetrate into a stud once the GRK makes its way thru the strapping, rockwool and sheathing. Then add another inch or so to bite a stud
The rounded head of the GRK will need inset in the strapping with a forsner bit. I like to set my GRK in a pattern every 2 feet or so. Makes it much easier to plain out your walls after they are strapped. If the wall is long enough, I would use a sting line. But a lot of times I just plain them with a 6 foot level
