Our 3D polyester fiber sound insulation board is made of recycled plastic (mainly plastic bottles), a high-quality environmental friendly material. The production process is completely physical and environmentally friendly, without waste water, emissions, waste and adhesives. The porosity of the sound insulation panel makes it have sound absorption and heat insulation properties. Our products have passed the certification of professional testing institutions and have good sound insulation effect. The noise reduction coefficient (NRC) of our products is 0.85-0.95, which means that 85% of the noise is absorbed by the panel, and only 5%-15% is reflected back to the room. In addition, you can also order professional refractory sound insulation panels to better protect your life. The special processing technology is that the sound insulation board has excellent flame retardancy and fire resistance. Our products are carefully designed. 3D sound insulation panels are more beautiful and have a sense of design than ordinary sound insulation panels. The product has different shapes and colors to meet the requirements of different levels of sound absorption and decoration. We can not only customize products according to your requirements, but also have a special design department to provide you with design services.
