Ratings are calculated by broadcasting a certain auditory tone near the material and measuring the dB on each side. Float glass may be heat-treated for additional strength. However, to accurately determine the acoustial performance of any window system, a sound transmission test is Standard for VT supplied laminated ceramic glass. In the USA, it is widely used to rate interior partitions, ceilings/floors, doors, windows and exterior wall configurations. Any wall’s sound blocking qualities are only as good as those of the material of the wall. Coating glass before heat treating it can cause more variance in the glass’ absorption of the heat, resulting in less control of the glass flatness. Meets ANSI Z97. 52mm laminated glass is 39.
