We are going to be installing a floating floor and will need to pull up some carpeting in some room, hardwood in another. Problem is that doors in the hardwood area are, as to be expected, on top of the hardwood. Now, the hardwood is about 3/16 thicker than the laminate flooring. So, we were thinking about possibly installing a separate layer of plywood over our existing subfloor to bring it up to the bottom of the doors for the floating floor to be flush.
Is this recommended? Is this possible? We don't really want to replace the door since they are in very good shape and quite expensive.
If it's possible, should the plywood be glued to the subfloor or nailed/screwed?
Thanks for all your help.
