A pioneering new glazing system with radically different looks and exceptional energy performance.

Size isn’t an issue with Lumi. With our highly stable structure, Lumi can be specified for larger than average windows.

A window that’s designed to last.

“By protecting all the elements that degrade inside the glazing, we were able to create a window that looks amazing and could survive our changeable, corrosive weather.”

Lumi doesn’t just look different, it’s designed to provide protection for what matters most.

Lumi is structurally very different from an ordinary window. This physical difference along with the addition of a range of high quality, security features, automatically enhances its security.

With our exclusive brake lock system from Winkhaus, our windows can be locked into any opening position by using the handle. All Lumi doors come with police approved “secured by design” anti-pick, anti-bump, anti-drill and anti-snap Kitemarked cylinder lock barrels as standard. Lumi Lift and Slide doors come with burglar resistance of up to RC2 (WK2) and Lumi Bi Fold doors come with Schuco multi-point lock system with shoot bolts, achieving a burglar resistance of WK/RC (DIN EN 1627).

Every Lumi window is made with a 50mm triple glazed unit of toughened glass. This along with the draught free, highly insulated structure offers an impressive level of noise reduction. All Lumi glazing can be fitted with restrictor stays and privacy glass.

Designed with an 80mm draught free, hidden double rebate, stormproof frame, Lumi has earned top class U-Values, while our non-corrosive exterior protects this energy efficiency for years to come.
