2011年8月8日 · Currently we space rafters 16" oc and use 7/16" OSB with H clips. We're in Dallas so we don't engineer for tremendous live loads for an asphalt shingle and we feel comfortable with 16" oc rafter spacing and 7/16" OSB decking. I'm contemplating upgrading to 1/2" or even 5/8" OSB though to reduce roof sag hopefully to nil.

2007年7月26日 · Anyway, I did the roof but I think I'll stick with OSB sheathing, there aren't any voids that I have ever found, and it seems to be stronger than 1/2 inch plywood, unless you buy 5/8 or 3/4 inch stuff. But the Canadian stuff is the best.

2015年1月4日 · I am going to start construction on my new home in April located in Dallas, TX. I have been reading up on types of sheathing and looking for more information and experience on what is the best sheathing to use in this environment. I'm leaning towards the zip system versus OSB with Tyvek wrap but would like some feedback. Thanks

2006年10月17日 · I use Advantek :thumbup: OSB for floor and roof sheathing. It took me a long time to make the change from plywood, but I am impressed with the stuff. It also has a 50 year warranty:w00t: , I don't know of a ply that has such. The regular OSB is different however, it will swell if it smells rain. I do use it, but we cover it ASAP when we do.

2008年4月28日 · When I was a Super for a production roofing corp in Arizona, the tract houses were sheathed with OSB, but the edges (about 16-24" in) at the perimeter of the roof (eaves & rakes) were all done with plywood because if they got wet, they'd hold up better. The problem with OSB is that "if" it gets wet, there's no fixing it or dealing with it.

2007年2月16日 · I have seen a lot of different ways of people nailing off their sheathing. I have seen framing guns used for everything from roof, wall and floor sheathing with ring shank 8's. I have seen coil nailers used for the same purpose but that nailer shoots a lot faster and doesn't jamb up as much. I have also seen staplers used for walls and roofs.

2023年5月7日 · Meanwhile the upper OSB layer is rotting away unknown and causing serious structural damage to the SIP integrity. This one is a big mess soon. Brother in law has a pole barn with 2' OC trusses, 1/2" OSB, with failing and leaking screws on steel roof panels being the vast majority are just in the OSB. It's really a bad mixture over time.

2009年5月10日 · I've worked on a few places that had isocyanate directly on the studs (all seams taped), then 1/4"OSB on top of that with tyvek on top of that. New construction, energy efficient, easily passed inspection. Rather than using the sheathing to stop racking they had cross bracing wherever possible and convenient.

2007年2月16日 · We used to use plywood but have been useing 5/8 osb for years now and would nver go back.Have had several roofs where plywood delaminated and left little humps in the roof, never had 1 problem with osb.Sure plywood is stronger but osb is strong enough if you use 5/8.For the price differance its crazy to use ply.I wouldn't if it was the same price!

2004年12月29日 · That Amazing i dont know of one builder here in minnesota that uses 5/8 for roof decking most use 7/16 OSB and have seen a few who use 3/8 cdx. 7/16 is adequate but you dont want to have to many people or shingles in one spot. 3/8 is insane walking truss to truss. Have never had a problem with 7/16 or 1/2 inch OSB as far as sagging in 15 years.
