Effective sound insulation is in great demand in open-plan office workplaces, large domestic rooms, spacious halls, and meeting rooms. The pleasant working atmosphere has a positive effect on the health and wellbeing of the employees and enhances their performance.

OPALWHISPER® panel absorbers are made from PVC and are designed to solve acoustic problems by means of ceiling suspension or wall or glass-panel mounting. The various film elements can be easily attached or detached using a variety of mounting systems. The films can are designed for flexible use.

The panel absorber can be used as an inconspicuous design element for providing sound insulation.

The high efficiency of OPALWHISPER® in improving room acoustics is based on its micro-perforations. Using a patented process, the films are perforated with holes of 0.2mm in diameter at a distance of 2mm apart. When sound waves impact on the film, there is a physical reaction in which the sound energy is transformed into heat at the edges of the perforations, resulting from friction. This results in a considerable reduction in reverberation times and in turn reduces noise levels.
