During the design of building structures and elevator hatchways all the requirements for the elimination of noise, vibrations and their spreading must be considered. According to a special regulation, the level of noise in an elevator with the machine room must not exceed 75 dB. INTERTECH plus s.r.o. has developed a special anti-vibration mat, absorbing vibrations of elevator hatchway structures by almost 60 %. They are versatile anti-vibration and absorption boards which significantly increase resistance of building structures against dynamic stress and effects of shaking by their properties. The product is a mat made of a rubber mixture based on rubber granulates of different sizes and stiffness.
