About Velux
Velux is the world's leading manufacturer of roof windows, skylights, and sun tunnels, with operations across more than 40 countries and a US manufacturing and distribution base in Greenwood, South Carolina. Founded in Denmark in 1941, Velux pioneered the modern roof window concept and has spent eight decades refining the engineering, flashing, and glazing systems that make daylighting through sloped and flat roof assemblies practical, weather-tight, and architecturally relevant.
Velux's North American product line spans manually operated and solar-powered venting skylights, fixed (non-venting) skylights, curb-mounted and deck-mounted configurations, sun tunnels (tubular daylighting devices), and complementary blinds, shades, and controls. The brand's signature product — the roof window — is designed to be both a ventilation opening and a source of controlled daylight in rooms where conventional wall windows are limited by roof geometry, privacy, or building placement. Velux products are sold through roofing contractors, window dealers, and big-box retailers, with strong penetration in the residential new construction and remodel markets.
For architects, designers, and specifiers, Velux is the primary reference for residential and light commercial skylighting. The company's flashing systems, glazing options (tempered, laminated, impact-rated), energy performance documentation, and remote-control operation systems are the most comprehensively documented in the category. Specifiers should confirm flashing compatibility with roofing material and climate zone glazing requirements early in the design process.
