摘要： A method for manufacturing an underlay material (8) to be set under parquet or a laminate, the underlay material including a sheet material layer (1) and a flexible cellular plastic material layer (3) bonded under the sheet material layer, and a bottom surface of the cellular plastic layer being processed for providing an air space, whereby the bottom surface of the cellular plastic material layer (3) is processed by melting the cellular plastic material locally for providing an air space (9) and for simultaneously bonding the cellular plastic material layer to the sheet material layer (1). An underlay material manufactured by such a method is also described.
