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

Your perfect house should reflect you, your world, and how you choose to live in it. See your living space in the best light possible with a brand new style of glazing. Minimalist wall to wall glass that brings a new level of brightness to every aspect of your home.


Lumi is a groundbreaking new range of customisable, matching frameless windows, bi-folds and doors from Apeer. With their completely flat, uninterrupted profile, these radically styled windows bring a wall of light to your home.

Hidden under the ceramic colour lies the secret to Lumi’s strength – energy efficient triple glazing that has been structurally bonded to an internal core of high strength, glass-fibre reinforced profiles. This intelligent piece of engineering is the first of its kind on the market, bringing all the design benefits of frameless glazing with all the strength, security and internal styling of more traditional windows and doors.

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


A consistent, high quality finish of architectural detailing can have a surprising impact on the overall success of an interior. Lumi is one of the only wood or PVC alternatives with an interior finish that can be matched across the trims, window boards and sills of all the windows, doors and bi-folds in your home. Available in a choice of eleven styles, four of which are convincing and subtle wood grain finishes, Lumi is the simple way to upgrade your home interiors.


Lumi has been designed to conserve energy and withstand even the most extremes of weather. With a state of the art 50mm insulated triple glazed unit, an 80mm draught free double rebate system with a double gasket seal as standard, Lumi windows are among the most energy efficient on the market.

The 50mm triple glazing is made from 6-4-4 toughened glass, insulating the home against both cold and noise. The flush glazing completely hides the glass-fibre double rebate stormproof frame, offering exceptional U-values and unparalleled weather protection. We can also supply this triple glazed unit with two panes of low emissivity glass filled with argon gas for enhanced energy efficiency.

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).



Lumi bi-folds might look like and behave like Lumi windows and doors, but they work slightly differently. Their 62mm triple glazed insulated glass unit is structurally bonded to a twin seal thermally broken aluminium frame with insulating foam inserts. However, they are one of the most energy efficient bi-folds on the market with excellent U-values. And they have achieved burglar resistance of WK/RC (DIN EN 1627) with Schüco multi point lock system with shoot bolts.


The highly thermally insulated aluminium lift-and-slide Lumi Slider with its perfect watertightness, excellent sound reduction and burglar resistance up to RC2 (WK2) is second to none. The modular profile insulation achieves U-values of 1.1 W/(m2K). With large opening widths and easy operation, Lumi Slider offers new system solutions for large projects and luxury homes.




As you would expect from Apeer, the manufacturers of some of the most advanced glass-fibre reinforced doors on the market, Lumi doors are an impressive addition to the Lumi range. Available fully or partially glazed, every Lumi door comes with police approved, ‘secured by design’ anti-pick, anti-bump, anti-drill and anti-snap Kitemarked cylinder lock barrels as standard. Plus, our triple glazing provides so much insulation against the cold that they have achieved an enviable A rating in energy conservation.


Top of the range glazing requires top of the range security, which is why we have invested in the Lumi brake lock system from Winkhaus, which allows the window to be locked into any opening position simply by using the window’s handle, exclusive to Lumi

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.
