Konto joined Acoustic Facts for a few weeks ago. As they describe themselves they are a world leading expert in interior acoustics. We believe in that statement as well. We wanted our Konto Acoustics acoustic panels to be tested by an independent professional organization that Acoustic Facts is. Acoustic data that has been certified, evaluated and broadcasted by them gives credibility for the use of our acoustic solutions throughout the design process.
Here is a link to our acoustic panels broadcasted in their service. Although Konto Acoustics is presented there as ceiling material due to technical reasons Konto can be applied to walls likewise.
