The Sono lock max is a self-regulating sliding vent with a high noise reduction. It consists of a rain cover on the outside and has an inner profile of accoustic mousse. The vent is self-regulating and is not very deep.
This slide ventilation can be used for all window depths with wood, plastic, and aluminium windows, both new construction and renovations. The Sono lock Max is always fitted with acoustic mousse, but can be extended with an acoustic channel in the slide to achieve the optimum acoustic dimming.
