Velux -VS -Manual Fresh Air skylight With Solar Shades

Manual  The No Leak Skylight carries a 10-year installation warranty, plus 20 years on glass, 10 years on product, and 5 years on shades and controls. Silicon dioxide makes Neat® glass exceptionally smooth. In fact, it's much smoother than ordinary glass so water disperses evenly (sheets off), and evaporates quickly, greatly reducing water spotting. Reduce unwanted outside noise by up to 25% less than a standard double pane glass, and up to 50% less than a plastic skylight. Adding fresh air and ventilation to a home is essential to health and well-being.
