Laminated glass, acoustic grade with PVB interlayer
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
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
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.
