What is Clean, Quiet & Safe Glass?

Clean, Quiet & Safe Glass is the name for the dual pane laminated glass that comes standard on VELUX's Solar Powered and Electric "Fresh Air" Skylights and is also available for our other models. Clean, Quiet & Safe Glass is named for how it's better than standard glass used by other skylight companies: Clean: Silicon dioxide is used to make the glass exceptionally smooth so that water disperses evenly, evaporates quickly, and greatly reduces water spotting. Additionally, titanium dioxide reacts chemically with the sun's UV rays (even on cloudy days), causing organic materials on the glass to decompose. When it rains, the decomposed dirt is rinsed away, leaving the glass almost spotless. Quiet: This glass reduces unwanted outside noise by up to 25% less than a standard double pane glass, and up to 50% less than a plastic skylight. Safe: VELUX recommends - and building codes require - laminated glass for out of reach applications.
