Abstract
The invention relates to a panel (1) for a floor covering with a layer (2) consisting of a thermoplastic material, which is applied between the underside of the panel (1) and a further layer (3). The further layer consists in particular of a very thin, strong paper impregnated with acrylate. The invention achieves particularly good footfall noise-absorption.
