Impact noise reduction and thermal insulation

Impact noise reduction is related to a floor covering that ensures higher insulation from impact noise, in accordance with ISO 10140-5. This is defined as the reduction of impact noise pressure levels, measured in the recipient room after installation of a floor covering on a 140mm thick reinforced concrete floor.

It is common to associate the use of materials composed entirely of rubber to guarantee this vibration control, however, the use of such materials can cause several problems in their application and in terms of vibration isolation.   This occurs because the characteristics of the overall system are not considered. Char…

10 % reduction in noise transmission when compared to a standard natural stone. Improved sound absorption.

This compound is then heated, pressed into a mold and cut into sheets.   The combination of cork backing with wool felt creates a durable and acoustically absorbent wall covering system. Although there are different variations, in function of the models, the coverings register noise reduction coefficients (NRC) of up t…

To attenuate IIC noise in floor assemblies, a Resilient or Sound Control Underlayment is required. The correct Underlayment will provide the resilience required for code complaint IIC noise reduction and the structural stability required for a responsible flooring installation.
