Reynaers Aluminium has announced its latest product to help meet the growing demand for low energy and passive buildings. 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.
The improved insulation levels are achieved by employing an insulation technology (patent-pending) which contains a special foam, firmly fixed in the chambers of the insulation strip, making the normal handling, processing and composing of the window and door profiles possible.
A special set of gaskets assures not only the insulation, but also the wind and water tightness of the system. After insulation, air tightness is the most important factor determining the energy-efficiency of a window or door.
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.mThe very high stability of the CS 104 allows it to support triple glazing for 1,400mm x 2,400mm 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.
