    Question Question about Shed Siding - What Fastener?

    Quick question about siding for my shed.

    The plans call for using 1/2" cdx as the exterior sheathing for the shed. But that plan also calls for using horizontal cedar siding.

    I'm not planning on doing the cedar siding, as I'd like for the exterior of the shed to somewhat match the house. Our house has something more like this on it.

    96 in. Composite Panel Siding

    If I use these types of panels, do I need to sheath the shed in 1/2" cdx?

    My shed has the same siding. Installed directly over the studs.
    If I was going to do it over again I would use plywood sheathing. The main reason is durability. I'm always banging my tractor or something into the walls inside the shed and cracking the siding.

    Brent yea you can go with that alone. If you do decide to sheath it before adding your siding i would just go with 1/2" osb. Now just to confuse you futher how about taking that sheathing and put it on the inter walls and your siding on the exter.

    Yeah what Bob said. Years of wind, banging, plywood sheathing will pay off tenfold.

    1/2 OSB and Sheathing it is then!

    And putting the 1/2 osb on the inside will give it a more 'finished' look, so I reckon that's what I'll do!

    Thanks Guys!

    The biggest issue that always pops up with that type of siding is rain hitting the ground and bouncing up under the siding which will cause it to rot.

    Personally, I have never done a siding job without sheathing, then cap the bottom of the sheathing and wrap it. I know it is a lot of extra work for a shed, but it will last much longer and give you a lot less headaches down the road.

    So what does 'cap the bottom and wrap it' mean? Fortunately, we are in a pretty dry climate, but I would like to do it right and learn a bit about things while I'm at it.

    Capping the bottom of the sheathing with c-channel.....let it ride about 3 inches. The BORG sells it......as for wrapping it....I use Tyvek, but since you are in a dry area, I would forgo that..

    Did you ever see a structure that was rotting close to the ground? That was caused by rain bouncing off the dirt and kind of splashing up behind the sheathing. The capping eliminates that issue.

    ****from another site****

    "The plywood extends beyond the walls original vertical plain leaving an exposed open grain and its another in the steps to seal the bottom of the plywood to prevent wicking. "

    That being said, this wicking effect on the end grain is what the capping solves.

    Hope this helps

    Brent here is a photo for you I had from a while ago.

    You can see the house wrap, but if you look at the very base of the sheathing, you will see a 3 inch piece of c-channel nailed to cover the end grain of the sheathing.
