PET (Polyethylene Terephthalate) panels in stage works refer to acoustic panels made from recycled PET materials, designed for sound absorption and diffusion in theatrical environments. These panels are lightweight, durable, and environmentally friendly, offering effective noise reduction and improving sound quality on stage. Their versatility allows for various designs and finishes, making them suitable for both aesthetic and functional purposes in performance spaces. PET panels can be easily installed in studios, theaters, and auditoriums to enhance acoustics while contributing to sustainability efforts.
