Disoriented strand board

Recommended Posts

What happens when you use OSB scraps to finish the job, and you lay a peice up oriented vertically instead of horizontally? You get a dip in the roof, that you have to go back to and fix, somehow. They saved about $10 on a 1/4 sheet of OSB. Tsk, tsk.

I could be wrong but..... I doubt it's so much the orientation as it is the lack of support by a min. 3 supporting members.

As far as a repair goes, I would just push the sheathing back into place and nail in some 2x4's run perpendicular to the trusses.

Well I think it is the orientation, so there. [:)]

The majority of the strands are laid up in one direction, and the sheets are stiffer in that direction. Same as plywood has more veneer laid the long way, so that is the only way to lay it up.

As far as a repair goes, I would just push the sheathing back into place and nail in some 2x4's run perpendicular to the trusses.

I suggested that may be possible, easy fix. But I also warned my client that the shingles may not lay flat when they're done, and that he should check for that.

Also, it is not technically correct to drive a bunch of nails into truss members, not that it would matter much.

I would agree with John. The OSB is similar to plywood with layered veneers. The orientation of the sheet should be horizontal to the framing. This ties the trusses together and provides for more surface support for the OSB.

I would agree with John

Well of course you do, you're both Canadians, eh.[:-monkeyd

Serious question for you John.....

Is it really technically incorrect to install a few framing nails through a top chord of a truss? The APA website shows solid wood blocking as an option..blocking

A nation of woodcutters.

Brandon, you are right about that. Blocking is OK.

I'll have to drive by that place and see how the repair turned out.

It's all scrap. They took the Idea from Armour. It's the Spam of Wood.

I'm thinkng more in the way of this is what happens when you use mulch and resin to build a house you expect to still be standing in a hundred years. It's junk. I don't care which way you run it.

Builder violated this from Brandon's link:

"Each piece must be continuous over at least two spans".

As we reduce house design to the absolute minimum, every single nail becomes critical. End result - we'll all be living in tents!

I like plywood.

Did you ever wonder why they don't use OSB for concrete forms?
