Matis metal panels consist of a metal box structure in steel or aluminium, padded with high-density mineral wool and a visible perforated sheet on the sound absorption side.
There are two versions of metal sound insulation panels, depending on the strength of the noise to be excluded:
- the SKYWALL panel, with 95% sound absorbing surface, is particularly recommended for noisy equipment located outdoors (e.g. refrigeration units, UTAs, pumping systems in general)
- the STARK S1 panel, economical and with 60% sound absorption, is particularly recommended for the acoustic insulation of road and rail traffic.
