Osb


I am installing OSB on the interior walls and ceiling of a detached garage which will be insulated but it will not be heated very often and it will not have A/C. I would like to butt all the panels to each other without spacing but I wasn't sure if there would be an expansion problem. I don't know if it matters, but it will get a coat of paint.

Maybe I wasn't clear. I do not want to have any spacing and I've heard that none is needed, but I want more opinions. I know that spacing is not needed for carport ceilings and soffits when using plywood.

Re: Osb

Re: Osb


I spaced mine with a 10d finish nail and it's been there 24 years with no problems.

Re: Osb


If you wants just use some "h" clips for spacers

Re: Osb


Not saying it is right, but can't remember the last time saw a framer here use H clips or space osb.

Re: Osb


I framed plenty of houses with OSB sheathing using an 8D HDG nail for spacing. More often than not, the spacing was all but closed up before the WRB went on the walls. Of coarse, working on the coast, the humidity was always high.

In my experience, it's better to space it than to wish you had spaced it.

Re: Osb


I'm planning to do the same in my garage at some point. I plan to space for exapnsion. I'd be scared of it bubbling out in the middle with no room for expansion.

If seeing the gaps bother you, just rip down the scraps of osb & put the strips over the gaps.

Here we usually use them on the roofs. I don't ever recall seeing anyone space osb at all. At the same time I don't think I remember seeing any h clips in a long time either but im occasionally doing roofing, only when certain customers ask or when it's a really small job and i could use th money then subbing the job out lol.

Re: Osb


I didn't space the sheets in my garage either. No swelling. It's kept above freezing in the winter with a wood stove to heat it when I need it.

Re: Osb


My garage interior is sheeted and painted with osb. No spacing was left and no problems in eight years. It is code here to space wall sheeting on the exterior of the houses we frame. We generally use a 2 1/2 inch nail to hold the space.

The last job we did, the roof sheathing came in 95.75" sheets. It was pretty nice.

Re: Osb


Did a job like this at the end of summer. Didnt space it as per his request otherwise I would have spaced it with an 8d nail. Was out there last week to look at the next project. He has only heated his shop twice so far but hasn't had any issues.
