StoSilent Systems

Acoustic Systems for Interior Applications


Effective acoustic solutions are becoming increasingly important in modern architecture. Even during the planning stage, ways to positively influence the sound of a room as inconspicuously as possible is a major consideration. Ultimately, the way a room is perceived depends heavily on how it is heard, and seen, by those who use it.


At Sto, we have been researching this topic for over 25 years. Our aim has always been to provide you with the means and materials you need to design acoustically perfect rooms that look as good as they sound.
