CE certification for windows and skylights

The standards and tests give us consumers the necessary security - especially for new and innovative products, such as the sun tube. Our sun tube was immediately submitted twice to the critical eyes of the Certification Commission. Because up to now there has not been a standard for this type of lighting, the Lightway sun tube was tested in accordance with EN 14351-1 (for windows and roof windows) and EN 1873 (for skylights).
