SYLENCER is a noise insulation product for ventilation and exhaust air openings, for the protection of living spaces from noise. It enables air to pass through the appropriate openings in the building’s facade while preventing the entry of noise through the same openings. SYLENCER consists of a housing of expanded high-density polypropylene (EPP) and a noise-absorbing element of polyester fibres. EPP offers high damping and is easily and fully ecologically recyclable. The polyester fibres are hypoallergenic and 100% reusable, and are won from the processing of recycled PET bottles.
