MaxParete HSP H operable partitions provide high levels of insulation and acoustic comfort – with Rw-indices from 41 to 57dB (certified in accredited laboratories), have no length limits and can reach heights of over 11 metres. They consist of independent modular elements that slide by means of silent, low-friction trolleys on extruded aluminium ceiling rails, without the need for a floor guide. Each element is equipped with telescopic movable thresholds (lower and upper) operated by manual control that acoustically and physically block the panel.
