The W450 is an integrated opening retractable thermal insulation system of high standards that meets the modern requirements of energy efficiency, sound reduction, aesthetics and safety.

The wide range of profiles in the range offers a multitude of functional and aesthetic solutions, from straight or curved sections as well as the possibility of complex typologies such as aller-retour doors, flat mill pivoting windows and opening frames with "hidden leaf" to achieve high level aesthetics. The collaboration of the available profiles, combined with the high quality components and mechanisms, underline the versatile and ergonomic character of the system.

The non-negotiable priority of the system for maximum energy saving and high safety is ensured thanks to the possibility of perimeter locking and the use of glass-reinforced polyamide 24 mm, giving a thermal insulation index Uf=2.2-2.6 W/m2K and a sound reduction index Rw of 43 dB.

The reference point of the system is the use of the least possible visible aluminium with the W450 HS hidden leaf version that perfectly combines the feeling of a simple, simple and elegant aesthetic result with the safety and functionality of the perimeter mechanism.

The modern architectural line of the system is reflected, in addition to the modern aesthetics, in the minimum face height of 72 mm that maximizes the field of vision and allows the maximum possible penetration of natural light into the building's interior. The use of 31.8 mm glass-reinforced polyamides ensure high levels of thermal insulation with a Uf of 1.6 W/m²K, while special EPDM elastics and an advanced perimeter mechanism give the system high degrees of waterproofing and wind resistance.

The W4750 is a high specification, opening aluminium thermal insulation system, which combines the proven benefits of the W450 series with the highest thermal insulation requirements. Its impressive performance makes it ideal for private residences and buildings with high energy requirements and specifications.

The 39 mm glass-reinforced polyamidesthe multi-chamber EPDM central tire and the advanced perimeter locking mechanismgive the system superior performance characteristics, with a thermal insulation index Uf ≥1.2 W/m²K..

ALUMINCO's system W4900 is the top performing passive opening system in Greece that meets the strict criteria set by the German Passive House Institute (PHI). (Passive House Institute). The excellent thermal insulation performance Uw=0.78 W/m²K makes it uniquely suited to the implementation of passive building constructions.

In addition to excellent energy performance to passive house standards, the range combines the proven benefits of aluminium windows, enables robust high specification constructions and is characterised by a wide range of options sought by architects.

The pop-up system W540 is the upgrade of the well-known and successful ALUMINCO AL510 series.  The renewal with new profiles and construction typologies has resulted in the W540 . evolving into a modern and complete system..

The system enables for small, medium and large size constructions fulfilling any architectural or construction need. The inspired design offers ease and speed of construction. It places special emphasis on durability and functionality while being compatible with a multitude of components and mechanisms. Its special features make it one of the most versatile economical non-thermal systems on the market.

The special profile design offers a wide range of design options in terms of appearance, both in straight and curved lines for lovers of the absolute classic.

The W540 is a proven and reliable opening systemengineered and designed to meet a wide variety of applications.
