Room divider
Description
The room divider has two acoustic functions: sound insulation through the solid core and damping of the incident sound energy through acoustic elements with textile covering fitted on the front. The combination of both properties results in an acoustic separation with a high degree of damping. It consists of an upright panel construction with absorber elements mounted on both sides and is fixed with steel cables. The textile surfaces are available in polyester, pure new wool or blended fabrics with a wide choice of colours.
