In essence, a sightline measurement shows the thickness of a window or glass door frame. The term refers to the part of a frame that is visible when you are looking directly at a window or glass door.

The smaller the sightline, the more glass is visible. If your glass door or window has a slim sightline, it means it's effective at letting lots of natural light into your home. It also means your view to the outdoors from inside your house will be less obstructed.

A single ten-year warranty covers the whole system. We are unusual in the industry in providing a single warranty, and can do this because every single element of the Cero IV is manufactured at a single site by Solarlux and installed by our Yorkshire-based team as a Solarlux approved partner. This gives you peace of mind because there's no uncertainty over responsibility should any issues occur.
