Collectively, many things make acoustic windows unbreakable. The AIS Acousticglas* that we use to manufacture acoustic windows has a PVB layer that contributes hugely to making the windows unbreakable. It is the PVB layer alone that capacitates the windows to block around 50-60% sound reduction. Apart from it, all windows perfectly treated with new-age technology-based frames and accessories to ensure no sound transmission. For more details about the features and components of these windows, you can visit the windows section on our website or directly call us.
