ZIPS-Z4 soundproofing panel system with surface leveling system used in construction and reconstruction of buildings of any type to increase sound insulation of single-layer structures, such as: gypsum, brick and concrete walls, partitions, as well as reinforced concrete floor slabs. Extreme surface roughness available for alignment by the ZIPS-Z4 system is 50 mm.

ZIPS-Z4, sandwich-panel is patented in Russia and CIS countries.


ZIPS-Z4 soundproofing panel system consists of sandwich panels 42,5 mm thick and special finishing plasterboards AKU-LINE. Sandwich-panel represents a combination of 20 mm tongue-and-froove waterproof plasterboard layer and 20 mm fiberglass slab. Each sandwich panel contains eight vibration-isolating attachment points, through which it is mounted to walls or ceilings.

To lean against the wall of floor slab, the ZIPS-Z4 panel uses six special vibration dampers made of Sylomer, via which the panel clearance can be adjusted up to 20 mm and up to 50 mm using additional ST-elements.
