Frameless Windows and Doors

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

Lumi is the first true innovation the window market has seen for decades. Invented by a team of product engineers on the North Coast of Ireland, it performs every bit as differently as it looks.

Lumi is a ground-breaking new range of customisable, matching frameless windows, bi-folds and doors. 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.

External Finishing

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

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 eight styles, four of which are convincing and subtle woodgrain finishes. Lumi is a simple way to upgrade your home interiors. 

Energy Efficiency

Lumi has been designed to conserve energy and withstand even the most of extremes of weather. With a state of the art 50mm insulated triple glazed unit, an 80mm draught free double rebate system with a triple 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 we have invested in the Winkhaus high security lock with completely sealed hinges. These heavy-duty extras will allow Lumi to continue to work smoothly for many years.
