With the launch of the new CS 104 window and door system, Reynaers achieves unparalleled insulation values for aluminium profiles in the building industry, introducing a solution for passive buildings.


Reynaers Aluminium, leading European provider of high-quality, innovative aluminium systems, announces their latest offering to make major inroads in the use of aluminium solutions to meet the growing demand for low energy and passive buildings. It is known that all European countries will enforce zero energy housing regulations for all new buildings by 2020, with different time frames per individual country.

Unparalleled insulation values
The CS 104 is a new solution within the existing CS product ranges, adding the benefits of enhanced insulation values down to 0.88 W/m²K (Uf), thereby providing windows and doors fit for passive buildings.

Design and efficiency
The increased built-in depth (the vent is 104 mm deep) contributes to the profiles‟ strength and stability, giving architects and builders the design benefits of large, expansive glass surfaces combined with strong frames to allow them the freedom to work with innovative, energy-efficient and sustainable design alternatives.

The very high stability of the CS 104 allows it to support triple glazing for 1400mm x 2400mm window surfaces. This feature allows architects to design even larger glass surfaces, also with the highest insulated glazing available. This way, maximum use of sun energy for lighting and heating is possible which, in combination with energy-efficient architecture, adds to the energy performance of a building. In addition to the high insulation values, the CS 104 also performs exceptionally well in terms of water tightness. With values of up to 900 Pa for windows and 300 Pa for doors, the system is suited for extreme conditions such as coastal areas, and can be applied at extreme heights.

Whilst its ultimate insulation performance allows architects to use the system in low energy and passive houses, thereby reducing the use and cost of energy, the economic benefits of the system extend further into the domain of building management. Compared to other passive window alternatives, aluminium profiles offer long lasting functionality. It is not damaged by UV rays or moisture and does not rust, rot or bend. Moreover, due to its smooth finish it does not attract dust and sand, making it truly maintenance-friendly.
Recyclability

Aluminium‟s most important characteristics as a sustainable construction material is its high recyclability. Aluminium is 100% recyclable without loss of quality. More than 70% of all the aluminium ever produced is still in use today. More than 90% of the aluminium from construction and demolition waste is already being recycled, and 40% of the world‟s aluminium is now derived from aluminium scrap or „secondary aluminium‟.

Erik Rasker, Chief Technology Officer of Reynaers Aluminium: “Durable construction is about recyclability and energy-efficient manufacturing. In addition to that, the manufactured products have to contribute to energy-efficient buildings. Sustainable architecture is one of the most important themes in all of the developments that Reynaers has implemented in recent years, with the CS 104 representing a major new step in energy-efficiency.”

CS 104 selected for Solar Decathlon!
The Solar Decathlon is a biennial event, hosted by the US Department of Energy, that challenges 20 collegiate teams from all over the world to design, build and operate solar-powered houses that are cost-effective, energy-efficient and attractive. The winner of the competition is the team that best blends affordability, consumer appeal and design excellence with optimal energy production and maximum efficiency.
In 2011 a Belgian team of young architecture students from the University of Ghent was selected to participate. As a partner and sponsor, Reynaers Aluminium supports their project with its expertise and provides them with its latest technology to help them win the competition.

Reynaers‟ high insulated CS 104 was selected to be used in the Belgian team‟s so-called E-Cube: an affordable, do-it-yourself building kit for a solar-powered residence that is pre-engineered, factory-built and easily assembled without special skills. E-Cube is designed to show that living small can be comfortable and practical. It contains all of the technical components and modern amenities used in everyday life.
During the Belgian Batibouw Trade Fair (February/March 2011), the E-cube will be presented to the public. In summer, the E-cube will be shipped to Washington DC, where it will be entered in the competition.
