Lumi Frameless Windows

Lumi windows are cleverly designed, with the frame placed inside the glass panes to offer your home a stunning feature that is both structurally and physically different to any other window on the market.
The wall to wall glass allows your home to be illuminated with light, creating a brighter more open space in your home, giving you that Grand Designs feel.

Lumi windows are innovative in their design, with the large glass areas and hidden frames making them perfect for modern new builds or for renovation projects on older properties.

There are no exposed frames in Lumi windows, meaning no raised or mounted frames, no painted surfaces, and no exposed joints. As they’re locked in the glass panes, this means Lumi windows are protected to withstand the Derbyshire weather and won’t corrode or damage, giving you a low maintenance yet beautiful feature.

The state of the art windows are perfect for properties looking to make the most of their large walls and mesmerising views, as the fibre reinforced structure and latest fibreglass reduces the weight of the window, providing it with the exceptional strength and rigidity such a large feature would need.

As standard, Lumi windows are installed with triple glazing to give your home exceptional thermal insulation and energy efficiency.
The 50mm thick triple glazing makes for a window that not only looks impressive, but offers an impressive performance too, protecting your home against the colder weather. Triple glazing is also ideal for properties near a busy roads, bars or pubs, airports as the high-performance glass is offers excellent noise reduction.
Lumi windows also offer closed cell insulation packed in the surrounding structure of the window, strips of insulation between all 3 glass panes to stop heat transfer, and the hidden double rebate, storm proof frame to create a draught free, highly insulated window with superb energy efficiency.

To give you peace of mind, all of our Lumi windows are fitted with toughened safety glass on all 3 layers as standard to protect your home from any potential break ins.
Toughened safety glass is thicker and stronger than regular glass allowing it to resist severe force.
Lumi windows feature an exclusive brake lock system which allows the window to be locked into any opening position simply by using the window’s handle.
For additional security, Trade Windows offer Lumi windows with the option of restrictor stays and privacy glass to keep you and your family safe.
