EcoSky Series Thermally Efficient Unit Skylights

Our Acrylite® Satin Sky® 2 glazing is an innovative acrylic sheet that is a powerful sun reflector which greatly reduces solar heat gain, making it ideal for both hot and cold climates. Satin Sky 2 is infrared blocking, light diffusing, and 100% haze white.

EcoSky3 units are available with Lumira® aerogel filled multiwall polycarbonate panel laylites for improved thermal performance and excellent light diffusion with SHGC of .31 and a high VLT for maximum usable LUX delivery. EcoSky3 models meet IECC 2018 requirements in all climate zones.

fall safetySAFETY CONSIDERATIONS:

Skylights pose an inherent risk of injury or death from fall throughs, and the safety of others is of the utmost importance to VELUX. VELUX recommends that the customer, building owner or manager use additional protection with the skylight such as an exterior or interior safety cage, to enhance long-term safety. The building owner or manager is responsible for providing fall protection around the skylight in accordance with OSHA regulations. VELUX also recommends that the building owner or manager restrict roof access only to personnel who have been cautioned as to the location of the skylights, and warned not to sit, step or walk on the skylights.
