The goal of the system is to avoid the structure borne noise installing elastical mounts that are embedded in the concrete floating floor .The process of elevation is done once the concrete is dry. The AMC-MECANOCAUCHO type FZH mounts incorporate a polyurethane elastomer called Sylomer®. This material offers optimal elastic and mechanical properties for the application. The AMC-MECANOCAUCHO type FZH mounts can be manufactured in different densities of Sylomer® to match the natural frequency needed on the application. The process of leveling is simple and effective. The density of mount per m2 is1.12 and the distance between the mounts is 0,9m.
