New construction, Midcoast Maine, Zone 5. 7/16 osb with hydrogap. 2x6walls with 2×3 insulated utility chase. Can I skip strapping the outside walls or blocking the stud bays by nailing through the osb into the back of shiplap?The siding will get face nailed at top and bottom plates. Thanks for input.

Jeff,
How does nailing from one side or the other affect whether you need to strap or block the framing? If you aren't going to nail into anything solid from one direction, you won't find anything solid from the other.
I was told I needed to strap or block, since face nailing the vertical shiplap into 7/16 OSB wouldn't have enough bite. So wondering if I nail through the thinner osb into the back of the thicker shiplap from inside the house that would hold ship on. If not, I'll horizontal block the studs and nail ship conventionly.

Thinking the shiplap would be my "solid", nailing osb to backside of shiplap.
Jeff,
Q. "Can vertical exterior siding be nailed/screwed from the stud bay side?"
A. No. First, there is the "buildability" problem. (Are you going to get your 200-pound friend to lean against the siding as you nail it?)
Second, if you think that you can hold 3/4-inch-thick shiplap boards by penetrating the boards with the tail end of your nails, with only 1/2 inch or 5/8 inch of each nail penetrating the shiplap, you are mistaken.
If I were you, I would install horizontal blocking between my studs AND sheathing. Remember, your wall needs a good air barrier and a water-resistive barrier (WRB) in addition to well-fastened siding.
The purpose of a rain screen, as in strapping under siding, is to allow the siding to dry on both the front and the back. We know that vertical shiplap will cup when fastened directly to sheathing, since the back of the board stays damp as the sun draws the moisture out of one side. Strapping the wall allows the board space to dry out on the back.
The other issue is that if you ever need to remodel or change even one board, it will be almost impossible to remove it.
Thanks. The Yankee in me got the best of me.
