Abstract
A floor panel for floating floor of the kind comprising floor panels elastically supported by buffer members laid on a floor framing is characterized in that the floor panel is provided with a plurality of through holes, and supporting means integrally united to its underside at proper intervals. The through holes are uniformly distributed over the floor panel and so designed that they have an upper opening diameter of 5 to 20 mm and an opening area ratio to the upper surface area of the panel within the range of from 0.1 to 20% to prevent the air between the floor panel and the buffer members from compression and expansion.
