Hardwood Flooring Underlayment Paper. Floor covering: This is the finished, visible flooring surface, such as hardwood planks, carpeting, ceramic tile, or vinyl. The paper is installed just before the wood flooring and comes in rolls of various lengths.
Two of the reviews said they used the product as underlayment for interior flooring and said it is very effective in elimination floor noise.
This is the layer that you see and walk on.
Laminate flooring is thin and not solid like hardwood flooring. Hardwood floors do not require underlayment padding, but they may squeak and creak if you place the surface boards directly against the underlayment. If you're installing hardwood flooring in a larger building, remember to check the building requirements for underlayment.
