we recently drastically renovated our ranch into an open "colonial and added a screened-in porch in the back. We have a cement slab, and I'd like to know of some options for floor coverings, aside from outdoor carpeting. the room is not heated or insulated; the "walls" are simply wood- framed screened doors attached at the sides with wood trim covering where each abutts the other. The ceiling, a gabled roof, is covered in cedar planking. Any suggestions would be appreciated.
