Underlay Selection

Underlay for Laminate Flooring and Solid Woods. The type of sub floor you have decides what type of underlay to use, Concrete holds moisture, an underlay with a built in Damp Proof Membrane is a must (DPM) Hardboard or Plyboard sub floors require a standard foam because there should be no bumps or dips in the sub floor. Fibreboard is the best with traditional floorboards, they take out the unevenness of the sub floor, help reduce noise and retain heat. Elka 3 in 1 is used with Solid Wood or Engineered Boards, the wood sticks to the underlay, cheaper than using liquid DPM and wood glues.
