One of the most attracting features of laminate is the installation with a tongue and groove interlocking system. It is floated (meaning it's not attached to the subfloor) and if a board ever gets damaged you can replace it a lot easier than with hardwood nailed to the floor. You install laminate over an 1/8" cushion or pad that helps with wear and muffling the sound.
Laminate Flooring can be installed in almost any type of room whether it is below, above, or on grade. Floating laminate floors can be installed over wood flooring, concrete, linoleum, tile, or almost any hard, flat surface, but not on carpet and not over another floating surface. Laminate flooring is not recommended for wet areas such as bathrooms, saunas, and so on.
