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.

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.

Energy Efficiency

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.


Lift & Slide Doors

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.

Composite Entrance Doors

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 in UK.
