The Phonotamburato® is a sound-absorbing panel which, thanks to its properties, allows sound absorption (reducing reverberation inside the rooms) and insulation (preventing the sound from leaving a particular room). Ours is the first perforated structural panel that includes rock wool inside. In this way, the panel has three specific functions: sound absorption (if perforated); thermal and acoustic insulation. The panels are fireproof and waterproof and also allow the thermal insulation of the rooms. Deepening the sound-absorbing characteristics of Phonotamburato panels, there are three distinctive elements that guarantee them: the thickness (which also involves several layers of fibers), the number of holes and their arrangement (square, crossed, hexagonal, triangular design).
