Installing a subfloor over 2 x 6 treated wood?

We have enclosed our 12' x 16' porch. I plan putting down a sub floor over the treated wood decking. What type of moisture barrier do I need place between the treated 2 x 6s and sub floor? I plan on installing a laminate floating floor on the sub floor.

Thanks,
Ricky

Welcome to the forums!! Some things to consider. Is the deck floor level? May have a slight slant to it. It may need correcting before you install your subflooring. Your vapor barrier will be the underlayment of your laminate flooring.

One more thought. Don't forget to insulate and cover under the floor joists. Came to me in a dream . I usually will run R39 under and cover the bottom with at least 3/8 if not 1/2" BC or better plywood and trim the joints with lattice or 1x2's (preferred).
