Because of their transparency, they also provide excellent visual monitoring wherever they are used, minimizing the possibility of accidents. When used for noise control, the tough, smooth edged panels can significantly reduce noise from one area to another. The flexible transparent barriers have an STC rating up to 26. They are safe, non-toxic, easy to fabricate and install and can be cut with a knife or scissors. When used as thermal barriers, the flexible transparent barriers retain heat in warm areas or reduce the escape of cold in refrigerated areas to significantly lower energy costs.
