  • Patent number: 4589243
    Abstract: A flooring system comprising a foundation and underlayment on the foundation. The underlayment includes a plurality of parallel grooves. The flooring system also includes support members in the grooves, floorboards superposed on the support members and the underlayment, strips of rubber between the floorboards and the underlayment and between the grooves and fasteners for fastening the floorboards to the support members so that the rubber strips are in compression between the floorboards and the underlayment. The floorboards are superposed at right angles on the support members and the combined height of an uncompressed rubber strip and the underlayment between the grooves is greater than the combined height of one of the support members and the underlayment below one of the grooves.
