MAXPARETE HSP^® SECRET is designed to enclose small spaces while delivering exceptional insulation and acoustic comfort (with Rw indices ranging from 41 to 62 dB, as certified in accredited laboratories). It consists of a single element that slides on silent, low-friction trolleys along extruded aluminium ceiling rails, eliminating the need for floor guides and disappearing completely into a pocket within the wall. The element is equipped with manually operated telescopic mobile seals (lower and upper), ensuring both acoustic and physical closure of the panel.
