I've got a fairly old house with some old, beautiful, wood floors. Currently, downstairs you can feel the air moving up through the floors. I'm pretty certain there is no such thing as a sub-floor, just the hardwood planks. Once it warms up I hope to get the carpet out and find out for certain.
What I have been debating is my method for remedying the situation. I think my options are:
1. Pull up the old floor, lay a subfloor, and relay the old floors.
2. Lay luann over the old floor and buy a new floor.
I think 1 is more in my budget, but I'm not sure exactly how to go about it.
My other issue with all this is insulation, I live in a flood zone so I 'm not sure what I should use. I wanted to lay spray foam or foam board between battens on the subfloor and lay the old floor across the subfloor, the problem here I think is a lack of ceiling space, but I suppose that's a topic for another section.
