Securing wall sheathing
I have two questions about securing plywood wall sheathing:
1) Many local contractors are now using staples to secure sheathing instead of nails. I never heard of that. I realize that it can meet local code, if properly installed, but will it do an adequate job of earthquake resistance in seismic zone C? (moderate risk) We also occasionally get high winds or tornadoes.
2) The house walls are wood studs above floor joists, with raised heel roof trusses above the studs. I thought that it would be best to use the plywood sheathing to help tie together the studs to the sill plate and studs to the trusses.
But the contractor I’m interested in using was planning to sheath the studs before raising the wall, and then add a narrow strip of sheathing separately to the band joist below (and the raised heel above). That wouldn’t help tie the studs to the anchored sill plate below. Is this acceptable practice?
I forgot to ask him if he plans to use staples for the roof sheathing, too.
