Abstract

L'invention concerne un panneau de plancher en bois (1) comprenant un substrat (2) en forme de plaque en bois et/ou en matériau dérivé du bois. Selon l'invention, au moins le côté supérieur du substrat est muni d'un motif, de préférence un motif de type bois, et d'un enduit (3) transparent fermé, appliqué sur le motif, à base d'un liant organique, qui définit le côté supérieur exposé du panneau de plancher en bois. Toujours selon l'invention, l'enduit (3) du panneau de plancher en bois réalise un amortissement des vibrations dans la plage de 8 s à 22 s lors d'un essai d'amortissement au pendule selon l'EN ISO 1522 sur un échantillon du panneau de plancher en bois. L'enduit conforme à l'invention offre une perception satisfaisante du revêtement de sol en bois par l'utilisateur, présente une résistance à l'usure relativement élevée associée à un faible entretien et empêche largement les déformations du revêtement de sol en bois provoquées par des charges de petite surface.
