It's also easier to install because, unlike conventional solid wood flooring which must be blind-nailed to sub-flooring and sanded before finishing, laminated flooring is pre-finished and may be glued down or applied over a thin foam pad laid on the sub-floor. Another advantage of laminated wood flooring materials is that, because they're made up of multiple layers, they're less likely to suffer from humidity-caused expansion and contraction problems that commonly occur in moisture-prone areas such as bathrooms and kitchens. As with most products, the better quality is usually accompanied by a higher price tag and laminate wood flooring is no different. Using the best laminate wood flooring you can afford to meet the daily demands of some rooms may give better service and durability over the years.
