For further reading, our glass partner, Saflex, has created a comprehensive overview of acoustical glass performance. Pages 19-23 in the Saflex Acoustical Guide illustrate solutions like the Cityproof system that include interior laminated windows featuring a PVB layer, an air space, and an existing exterior window.
