Seal them and they last longer. But not good for attic flooring because of the humidity changes. My falat arse (if I had an arse) would fall through. When I insulated and NASA foiled my attic I paid $45 a sheet for actual plywood. Still cost me less than paying someone else just to NASA foil my attic. The savings in A/C costs paid it off in 3 years. A few weeks ago I had my A/C units replaced, Goodman 12 years old for Bosch and I have to wait and see if it was a good choice. These are freon units not insane butane.
