floor underlaymentI have a crawl space under the house (raised foundation). My subfloor are made of wooden planks. I would like to put laminate (living and family room) and carpet (in bedrooms) and tile (in kitchen & bathrooms). What kind of underlayment should I use for each of the flooring? Below is what I think.
