This type of interior lining, with defined grades of sound absorption, is a very attractive finish suitable for offices, studios, computer rooms and switching stations. It consists of slotted tubular chipboards covered with real-wood veneer (flame-retardant as per DIN 4102, class of incendiary material B1 or B2).

The chipboards are either permanently fixed to a wooden framework or they are suspended into a steel sub-structure which retains the full modularity of the facilities construction.
