Safety glass composed of two or more glass layers bonded with acoustic PVB interlayer, providing enhanced sound insulation (STC 35-40), Grade A safety compliance to AS2208, and 99% UV protection

Overview
Executive summary

Acoustic laminated glass consists of two or more glass layers permanently bonded with specialized polyvinyl butyral (PVB) interlayer ranging from 0.76mm to 1.52mm thickness. The acoustic PVB features a tri-layer construction with soft acoustic core that decouples glass panes and dampens sound vibrations. Available in standard thicknesses compliant with AS1288:2021 for Australian building applications.
