Welcome to the Lignum component catalog

In the Lignum component catalog for noise protection, you can find the acoustic characteristics of many building components in wood. It is an online tool, which helps you to calculate the acoustic of the entire building in wood. It is the result of several years of work within the Lignum project together with the Swiss Federal Laboratories for Materials Science and Technology (Empa) and the Bern University of Applied Sciences, Department of Architecture, Wood and Civil Engineering (AHB).
