Apeer, the leading edge manufacturer of composite door sets, has entered the windows market with a groundbreaking new, structurally bonded window and door glazing system.

A first in its field, the radically styled new Lumi collection is set to bring the seamless sophistication of iconic glass structure to the residential housing market. The design-led range of frameless windows, doors, entrance glazing, French doors and a bi-fold door system was launched at Grand Designs (May 2-10, ExCel, London).

The new system has been in development for more than two-and-a-half years and represents an investment of nearly a million pounds for the company.

Offering a frame-free, ‘wall of light profile’ the triple glazed Lumi collection is distinguished by its fused ceramic colour border. This is available in eight different exterior colours – there are eight further interior finishes.

As well as being available in a full suite of matching designs, Lumi has a host of construction and performance benefits:

• stormproof design with flush proportional glazing (the double rebate is completely hidden)
• 50mm triple glazed (6-4-4) toughened glass for maximum insulation and noise reduction
• 80mm GRP double rebate frame offers exceptional U-values – as low as 0.7w/m2k on fixed glazing panels
• Triple gasket seal
• Double euro groove allows for versatile hardware options, concealed hinges and window locks
• High security Winkhaus lock system
• Kitemark glass and Kitemark Lumi composite front door options
• Fab & Fix hardware
• Variable clear glazing options
• Concealed hinges offer smooth action, high weight load opening and wide opening

Lumi comes with a 10 year guarantee (structural, mechanical and colour fast).
