The invention relates to a method of manufacturing a decorative heterogeneous floor covering comprising a sound attenuation effect with an acoustic impact sound reduction of at least about 15 decibels and sustainable slip-resistance properties. The method comprising the steps of: (a) providing a print layer comprising a print decoration/ design thereon; (b) providing a wear layer over said print layer to provide a print/ wear layer intermediate; and (c) providing a foam backing layer on the intermediate, the backing layer being capable of providing said sound attenuation effect; wherein between steps (a) and (b), the method comprises inverting the print/ wear layers intermediate before applying the backing layer to a reverse side / base thereof. |
