Building a Shed
You don't use PT flooring in your house, do you?
I build 'em wind and water tight. No need for PT flooring!!
Spend the extra money if it makes ya happy and secure! Same goes for the felt paper under the vinyl siding. Opinions are like.....you know the rest!

No you don't use P.T. on the floor in a new home,but on a new home the floor isn't usually less than 18" off the ground. If it was an addition that low you would be required to use plastic covered with stone,then your framing and plywood floor would have to be P.T. I don't doubt that your vinyl is watertight. I do believe from me experience in remolding industry thats you must try to do everything right to ensure your finish product is of proffessional guality.

I build 'em right, watertight!
If the shed was below grade, I'd use PT, however if built off the ground, on cement block with PT 2x4's as the flooring members, don't see the problem using regular plywood. I've never had a problem.
To each their own.........

Sounds like the original structure had some design flaws. The degradation of a plywood floor should not lead to the total dismantling of a shed.
Ants like moist places - ends of rafters and floor joist will wick mositure if exposed. Ditto that with plywood. (All of which should not be exposed to elements)
Might be time to prune the dead branches off the neighboring trees and do some cleanup if you have not already - ants can usually be traced backed to a source.
On your new building pay extra attention on how your structure sheds water. Put it up off the ground. Make sure water does not pond up on it,near it etc...keep the maintenace up on it and the area. If built properly you should not need to rely on a PT floor to keep the structure standing into the next century.
Post a picture of the plans or the completed shed!
Good luck,

Over kill of any structure is to over size the framing. Also the use of Tyvke over felt paper on a shed is a waste of money. Vinly siding takes carefull attention to installation of J channels especially around windows,(wind driven rain does get in!) your responsiblty is that it can get out!
The weakest link in a shed is the ply floor, being less than 18' off the ground year after year it bound to suffer. P.T. plywood all but ends that problem.
That's my point Think about it No one loses by building a better structure!
