With a QVM manual venting skylight, designed for self-flashed installations, any home can embrace the best of what nature has to offer. Opening for maximum fresh air, the venting skylight contributes to a home's proper moisture balance and comfort level by allowing stale, humid air to be released.
Green fact
VELUX venting skylights reduce the need for air conditioning during the year, and thanks to the chimney effect they create, they improve indoor air quality by removing moisture, odors and other VOC indoor pollutants.
