The thermal and sound absorption wall panel is composed of several joined strata of different nature, one of which is formed by a mineral fibre mattress (2). The mattress is between 35 and 45 mm thick. The panel has an external wood covering (4,6), drilled with many small diameter holes (8) equally divided on its surface, stuck to the mattress. The covering is formed by a sheet of rolled out wood (4) stuck on a textile layer (6). This textile layer is one of the materials from a group comprising felt, canvas and knitted fabric.
