Thanks for the advice...but another question:
I removed the w/w carpet and its foam underlayment from the floor over which I want to place the new pergola floor.
At the moment, it's base is merely 3/4 inch plywood over existing 2x6 rafters. Underneath this is a crawl space, 4 foot high, existing over ledge (this room was an add-on). There are moisture problems existing in this crawl space (two air inlets/outlets), such that I had to place a tarp over the entire ledge floor.
My question is for the to-be-finished floor above this crawl space: should I lay roofing paper over the plywood, and then the manufacturer's foam underlayment under the pergola flooring?
I am worried that any moisture "leaking through" the plywood joints and at the room's edging/corners may cause the new flooring to buckle, or expand/contract more noticeably than other areas of the house...
Thanks. |
