On request, nearly all our products can be delivered with self-adhesive rear faces, enabling easy, clean and time-saving installation – perfect for retrofit applications in rooms that are already in use.
Thanks to their open-cell structure, our noise protection materials absorb sound waves and effectively attenuate bothering noise. A satisfactory result can already be achieved by lining 30 to 50 % of the ceiling and wall surfaces.
Many of our noise-control products are classified as flame-retardant according to DIN 4102 or DIN EN 13501. Please contact your local authorities in advance for information about the required fire protection class.
