Lumi Seamless Windows & Doors

If you are looking for a contemporary appearance for your home, the Lumi range is the perfect fit, with minimalist wall-to-wall glass that brings a new level of brightness to every aspect of your home.

Lumi is a groundbreaking range of customisable, matching frameless windows, bi-fold doors, patio doors and front doors from Apeer. With a 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 engineering is the first of its kind to the market, bringing all the design benefits of frameless glazing with all the strength, security and internal styling of more traditional windows and doors for your home.

External Frame Colours

A subtle band of ceramic colour has been fused at extremely high temperatures to the glass inside the glazing unit.

Available in six different finishes, all colours are protected from the elements reducing the possibility of fading over time.

Plus, no external frames mean that maintenance and cleaning are every bit as minimal as the styling.

Internal Colours

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 Efficient

Lumi glazing units have 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.


Top of the range glazing requires top of the range security, which is why these windows us 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 windows in the UK.

Lumi Window Configurations

Lumi glazing can be configured to your requirements with fixed an opening units to suit your needs.

Composite Doors

Available fully or partially glazed, every Lumi composite door comes with police approved, ‘secured by design’ anti-pick, anti-bump, anti-drill and anti-snap Kitemarked cylinder lock barrels as standard.

Plus, the triple glazing provides so much insulation against the cold that they have achieved an enviable A rating in energy conservation

Lift and Slide Doors

The highly thermally insulated aluminium lift-and-slide Lumi Slider with its perfect water-tightness, 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.

Lumi Bi-Fold Doors

Lumi bi-folding doors 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.
