Protect what matters most

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.

Safe and secure

With our UK 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).

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.
