Hi,
I’ have read somewhere that by using 2x3 or 2x4 blocking instead of 1x3 on exterior walls, you save time on , by not having to drill for wiring, no taping elect. Boxes (vapor barrier), not disturbing insulation, the only 2 things I see; loose 1" of space, more$ for 2x3...what do you guys think? And is it better to run them horiz. 24"oc or vert. 16"oc...

I said for exterior wall but its blocking/furring nailers for interior sheetrock...

That's what I thought you meant but I've never seen it done except on ceilings to make them level and true.
