Technical progress is also advancing in the construction industry. Today’s modern buildings bear little resemblance to the classical construction methods that were common thirty years ago. This applies to building materials and systems as well as to building technology.
This change presents manufacturers and construction companies with a double challenge. On the one hand, they must constantly improve their products and develop new technologies in order to remain competitive and fit for the future. On the other hand, the use of new products often leads to unforeseen problems in other areas of building physics that have to be analyzed and remedied.
For example, composite thermal insulation systems (ETICS) can considerably impair the sound insulation of a façade if they are not designed correctly from the aspect of acoustics. The same applies - albeit to a lesser extent - to modern triple glazing, which are now found in most new buildings. Products such as sealing and installation foams and laminate underlays, which are often advertised by manufacturers for soundproofing, are almost ineffective in many cases as far as acoustics is concerned.
These examples, which are but a few, show that there is still a great need for research and development in building acoustics. As this requires not only extensive technical know-how but also cost-intensive structural and technical resources, e.g. for test laboratories and measuring equipment, many customers turn to Fraunhofer IBP for support. We have all the necessary prerequisites at our disposal.
In our research and development activities, we usually distinguish between two types of projects:
In recent years, our experts have carried out a large number of projects of both types. Some examples are:
