System 76

System 76 forms the basis of nearly all of our hybrid window range using KÖMMERLING profiles. It’s a market leader throughout Europe in terms of energy efficiency and other important criteria. The six-chambered design can also be adapted with the use of pre-foamed proEnergyTec profiles for Passivhaus applications.

Glazing up to 48mm including acoustic options and a range of over 80 foiled finishes further add to the impressive credentials of this system. As well as the foiled finishes, there are also the 22 colour variants using the pioneering proCoverTec surface finish technology.

The MD variant of System 76 has the added benefit of a centre seal for better weather performance, boasting a remarkable Uf value = 1.0 W/(m²K) as standard. Slim sightlines, a wealth of ancillaries and the ability to be fully recycled using the exclusive lead-free compound, Greenline are also key attributes of the system.

There are multiple opening options with combinations of openers and fixed lights, along with residential and inward opening French doors using the system. We also have full CAD drawings and technical images for architects and building specifiers from System 76, centre seal.

Range of colours

The hybrid nature of our products means that all aluminium external faces can be either powder coated, anodised or painted, literally opening up hundreds of different design possibilities.

On the inside, there’s the option of a neutral flat white, life like woodgrain options including English Oak, Irish Oak and pine, along with laminated solid colours. For the ultimate in performance there’s the unique surface finish technology of proCoverTec, providing true water and dirt repellent properties.
