·                                        泡沫玻璃是一种以玻璃质为原料，经过科学配制，再经高温焙烧而制成的具有大量的、相互贯通的、由表及里的吸声材料。主要作用于减弱反射声和混响声，缩短和控制混响时间，现已广泛应用大会堂、地铁、高架桥、工厂噪声车间、广播录音室等领域。吸声泡沫玻璃作为现代建筑新型的吸声材料，除了具有良好的吸声性能外，还具有许多无机玻璃的物化性能所赋予的优质特性。

·                                            1、能耐高温、遇火不燃烧；

·                                            2、无有害挥发物，对人体无毒性，无反射损害；

·                                            3、具有良好的化学稳定性，不风化、不老化、不受虫蛀、不会霉

·                                            烂变质；

·                                            4、遇水不软化、不吸湿、可用水冲洗，自然风干后仍保持原有的吸声性能和形状；因此，吸声泡沫玻璃不仅是室内装饰吸声材料，同时还能在室外环境条件下使用。
