4 season porch

I need to insulate under my 4 season porch which is up on pillars. I live in Connecticut and am concerned about moisture and cold and wind. Do I put the R38 batts paper against/away from the floor. Also should I put some tyvek homewrap underneath the batts before I put the PT plywood up.


Re: 4 season porch

What currently comprises the flooring of this porch?

If a wood floor..describe please and tell us what is on it for a finish.

Also, if this is a 4 season room...I presume there some manner of heating involved. What type .....and are there any ducts or plumbing running between the floor joists?...etc.
