Indoor environmental quality

VELUX offers roof windows and skylights with options that allow you to take advantage of daylight and views when your roofline does not permit vertical window placement. The VELUX SUN TUNNEL skylight offers daylighting in up to 95% of the interior spaces of residential and light commercial buildings, providing a better quality of light in the process. 

In addition, skylights installed with light controls such as exterior or interior shades will improve Indoor environmental quality all hours of the day. "Fresh Air" skylights contribute to greater thermal comfort and ventilation, another important factor for improving indoor environmental quality, by removing excess heat, moisture, odors, and other VOC indoor pollutants. They can also help reduce the need for air-conditioning during the year… thanks to the chimney effect that "Fresh Air" skylights create.
