Data Mapesilent is a Mapei software program used to verify the acoustic characteristics of buildings and calculate the thermal transmittance of partition walls. The program also allows you to verify if project requirements meet the specified legal limits.

With this software you can calculate:

• Weighted standardized impact sound pressure level - L’n,w
• Weighted sound reduction index - R’wa
• Weighted standardized level difference - DnT,w
• Thermal transmittance of partition walls - U

Data Mapesilent includes a comprehensive database of materials and components, and their relative performance characteristics taken from reports published by research institutes, which is simple to update by the user.
The procedures used to calculate passive acoustic requirements are taken from the standard EN ISO 12354.
