Multi-layer composite сar soundproofing material SGM Prime Cloud is an innovative acoustic material that uniquely combines three core principles of noise control: absorption, reflection, and insulation. Its multi-layer structure, featuring variable wave impedance, achieves record-breaking performance—absorbing up to 97% of sound energy at 2000 Hz. Furthermore, its patented three-dimensional geometry is fundamentally more effective than traditional homogeneous sound-absorbing materials.

This material is uniquely effective at absorbing sound across the key frequency range of human hearing. Specifically, within the 315-2250 Hz range, it absorbs sound 150% more effectively than traditional acoustic foams and absorbers available on the market. For the first time, a single material design combines sound absorption, reflection, and insulation principles. This innovative synergy allows it to utilize both non-resonant and resonant sound absorption methods simultaneously, providing superior performance.
