REYNAERS CHOSES TO WALK THE PATH OF SUSTAINABLE ENERGY

About 40% of the primary energy consumption is used in Buildings.  This is the key reason why, in the framework of the Kyoto protocol, European States aim to counter the greenhouse effect and decrease the energy use of buildings by 40% by 2020. In order to meet this goal, various measures were taken, one of which was the European Directive on the energy performance of buildings. These regulations primarily involve the energy performance of buildings, alternative energy sources, better use of climate regulation and lighting, bioclimatological concept, etc.
In this respect, Reynaers Aluminium has developed a complete set of solutions helping architects, fabricators and investors to improve energy efficiency of a building.  This includes highly insulated windows and doors, sliding doors, curtain walls, double skin façades, ventilated façades, brise soleil, and a complete BIPV offer.
In January 2010, it has pushed the boundaries even further in terms of insulation for Aluminium profiles, by proposing an aluminium window which can achieve an insulation value (Uw) < 0,85 W/m²K.

Insulation at its best

Reynaers solutions are fitted with a thermal break and have an insulation value that varies from normal to exceptionally high.
In two- or three-chamber systems the profiles are made up of two or three separate compartments, filled with air, referred to as chambers. Just like in hollow walls the air acts as an insulator in the chambers. In the space between the chambers we place fibreglass-reinforced polyamide strips (hard plastic). The longer these strips, the lower the U-value and the lower your energy bill.

Double façade

 
Fully glazed curtain wall façades have increased in popularity in the last 20 years. Modern office buildings can benefit from the aesthetically pleasing design and the transparency of a totally glazed façade. It can be quite a challenge however to find an optimal balance between thermal insulation and energy costs. Furthermore, the demand for natural ventilation in commercial buildings is driven by the growing environmental consciousness while at the same time energy consumption for buildings having to be reduced.
In this respect, double skin façades provide an ideal balance between maximal access to daylight and efficient energy control.
A ventilated double façade consists of a traditional single façade doubled inside or outside by a second essentially glazed façade. Each of these two façades is commonly called a skin, that is why double façades are often referred to as ‘ventilated double skin façades’.

 In order to get the best results, an intelligent control system and a building energy management system are required.

Reynaers double skin façades can be used for new-build or renovation of existing façades and can be applied to all Reynaers curtain wall and window & door systems.
