PET panels are a modern, ecological and, above all, effective way to improve the acoustics of a room. PET series panels (HexaPet, SqPET, TriPET) are made of at least 70% recycled materials. They have high values of the sound absorption coefficient, additionally strengthened by filling the panels with mineral wool. A great advantage of the panels made entirely of PET and mineral wool is their very high non-flammability class (reaction to fire class B-S1 according to EN 13501). The panels are available in several attractive colors with the possibility of additional printing, which translates into an infinity of possible forms.
