Spacing and attachment of rain screen materials (specifically Sturdi-Strips)
Our wall system is double stud, the outer wall is 2x4s 16" OC with 1/2" Advantech sheathing. Siding is quarter sawn spruce clapboards (longest pieces are 6').
We are planning (and have purchased) to use Cor-A-Vent Sturdi-Strips and the SV-3 vents, this is a 3/8" rain screen gap.
My assumption is that best practice would be to:
-staple (about 1-1.5" length staples) the Sturdi-Strips in line with our 16" OC studs?
-then the clapboards would get nailed along this same interval?
-at areas where a clapboard ends off a stud, it would be ok to staple a small piece of Sturdi-Strip and nail the clapboard into the sheathing (because 1/2" Advantech is pretty strong)
Or, from another perspective, is putting a Sturdi-Strip every 16" excessive? Should we not pay that much attention to the studs and just rely on the sheathing for our staple/nail base, say every 24" or so?
