VELUX VCM operable “Fresh Air” Skylights can be opened to create a chimney effect that draws air upward to improve air circulation and air quality within your home. They can be installed on a flat roof at 0° up to a 60° roof pitch on a site-built curb. Bringing natural light into a home through a skylight decreases the need for artificial light while maintaining privacy. Installing a skylight is one of the most impactful ways to enhance the brightness and beauty of a room.
