A:  That is the same thing I'm doing with this product. It's always better to protect your flooring from any moisture for longevity of the flooring. It will also help with sound proofing so you won't hear footsteps as loud. I would definitely recommend using this product. This is the lowest price I have found and I shopped around. It's as good as blue hawk Underlayment if not better, and ten dollars lower per 100 square feet.

A:  Technically, I'm not certain if you need it. However, I would recommend it as it also acts as a cushion and a noise barrier. Laminate is hard surface and a barrier like this will muffle footsteps. And, since a laminate floor "floats" I think it is a good idea to have something soft under it.

It is important to confirm with the wood flooring manufacturer, the approved substrates for the installation and the use of underlayments.(see manufacturer's installation manual) Unison is approved over concrete and wooden substrate material.
