Additional sound insulation panels ZIPS-experience of 20 years of application
* Presenting author
In apartment buildings and offices is often the task of increasing the sound insulation of walls and ceilings from airborne noise. Traditional methods of solving this problem, gypsum plating on metal or wood frame - have low efficiency. This is, in particular, due to transmission sound vibrations through the frame and the presence of a large number of wall lining elements that must be properly performed during installation. The frameless panels of additional sound insulation (ZIPS) were developed in 1999 in Russia. They have high rates of additional sound insulation (9...18 dB) in depending from thickness of 43...120 mm. This system was patented and is still widely used. In addition, the system provides the necessary strength and ease of installation. Over 20 years, the system has undergone several upgrades. The article describes the physical principle of the ZIPS-system, the data of laboratory and full-scale acoustic measurements, latest modification of the system with adjustable mounts.
