Hi, a couple of simple questions.
I have a pine subfloor which runs in the same direction as the solid wood flooring I am laying down. So, I'm told I need to use 5-6mm plywood or hardboard over it to make the floor as level as possible.
1 - Can I use underlay such as the fancy foil stuff (e.g. High Performance Underlay, Cushion Acoustic Gold Underlay) if I'm secret nailing/screwing the solid wood flooring down?
2 - If not, what type of underlay is suitable?
3 - Does underlay go above or below the plywood/hardboard?
Also, are "hardboard" and "hardboard underlay" 2 different things or one and the same?
