Zenon Evolution might not always be the best choice for the project, however it brings many benefits. The glass reinforcement comprises continuous strands that run the length and width of the rooflight providing greater levels of tear resistance and greater safety without having to make the rooflight thicker. This means that it can be manufactured to a sharper profile shape to match the metal sheets better, under at the top and over at the bottom. This makes the sealing of the rooflight easier and more reliable.
Due to the increased glass content, the level of light transmission through the Evolution product is less, but the diffusion is greater. Lower levels of light transmission result in lower levels of solar heat gains, therefore greater areas of rooflighting can be used to improve the uniformity of light within the building and avoid areas of shadow.
The stronger thinner product uses less raw materials which reduces the amount of embodied carbon in the product and can also be more cost effective compared to thicker alternatives. Please see FAQs about design considerations, for more information on why specifying rooflights is an important component within building design.
