Topperfo-Micro panels are used for sound absorption. Their perforations have a diameter of only 0.5 mm which makes them almost invisible – thus producing an attractive appearance. This design is possible thanks to an innovative manufacturing process through which almost all kinds of wood panels are able to be micro-perforated. In this way, solid, multi-layered or melamine-coated wood panels as well as panels already veneered by customers can be converted into acoustic panels. This opens up a host of design possibilities for architects.
