PRODUCT DEVELOPMENT
• Industrialised products.
• Lightweight products.
• Multi-layer systems.
• Modular systems 2D-3D.
• Junctions.
Acoustics for Timber based Lightweight Buildings and Elements
The acoustic performances of buildings made of traditional heavy structures and elements can be predicted from the performances of elements involved using standard series 12354.
When prefabricated or lightweight construction solutions are used in buildings, standard methods to design and predict the acoustic performance of buildings from the performances of elements EN 12354-1 and -2, are no longer valid.
In consequence, further work is needed related to the laboratory characterization of building systems, the behavior of junctions between prefabricated and/or lightweight components, the use of resilient materials, etc.
