WebThis feature is more prevalent in thinner glass than thicker glass. Expect roller wave to be present in glasses 4mm – 6mm. Glasses from 8mm – 12mm have slight roller wave, whilst glass thicker than 12mm have minimal roller wave. Please note that if 2 layers of TSG are to be laminated that the roller wave effect could double. WebRoller wave is a common form of this optical distortion.

WebAug 6, 2024 · 5.1 This test method is a procedure for determining the peak-to-valley depth and the wavelength of roll wave in flat glass and then calculating the optical distortion resulting from that roll wave. Peak-to-valley measurements provide a means of monitoring the roll wave distortion in a heat processed glass product. WebWhile these products are safer and stronger than typical float or annealed glass, the process that heat-strengthened and tempered glass undergoes introduces roll-wave distortion—a sinusoidal relief in the glass surface, often with regular peaks and troughs, which can result in visual distortion. kids reading chair air
