Are you stating that the guy nailing zip sheathing on the side of a house talks to the engineer who designed it?
- JKCalhoun 5y agoMy assumption: that the guy is even nailing ZIP sheathing is doing so because some engineer determined it was an improvement over previous construction techniques. (But maybe it is just cheaper.)
- Inhibit 5y agoIt saves on labor. ZIP doesn't require an extra layer for impermeability of the OSB; just seal up the joints with acrylic tape and you're done. Better? No idea. Although there might be less to screw up unless someone cost-saves by not installing the spec tape (it really is necessary).
- bluGill 5y agoWhat does better mean? OSB might test stronger, but the zip is strong enough for anything a house will actually face. Both will fail in a large tornado, both will survive surprisingly high winds (zip is certified for high wind and seismic loads). There is a place in the middle will OSB will do better, but that is a very small place. ZIP will let water vapor out, so your walls won't rot out. So if you want your house to last OSB is actually worse (though OSB houses have lasted a long time with no problems so this is again on the margins).
