Using OSB undera rug

[radstorm61]

Hi all, it's been awhile since I been here. So hello I am planning to put down some area rugs on my sun porch area. They are 5x8 and I plan to use about 3 of them side by side. It is on a concrete slab so I want to put down some 7/17 OSb under the rug to keep it off the cold concrete in winter. Should I put down down some plastic sheeting between the concrete and the OSB as a moisture barrier of sort?

Thanks

Any suggestions?

the plastic sheeting wouldn't hurt but since the slab isn't heated why go through the expense.
