Climate change (storms, floods, excessive heat, cold snaps, etc.), which is on the increase these days, is forcing professionals in the building and civil engineering sector to adapt their products and modify their working methods. Customers are increasingly aware of the need to choose windows and doors that can withstand these extreme external factors.

The mechanical performance of a window is essentially measured by three criteria:

• Air Permeability (ability to manage air flows to prevent them from recirculating in the house, while ensuring good ventilation).
• Water-Resistance (ability to prevent water penetration and evacuate water infiltration and condensation).
• Wind Resistance (ability to prevent sudden gusts of wind by not opening the window).

Based on this data, several technical institutes can carry out AEV (Air, Water and Wind) tests on exterior joinery to determine its mechanical performance.

Our MR68 mm double-glazed wooden window profile has been thoroughly tested by the FCBA technological institute in Bordeaux ( France), and the results obtained are among the best on the market, as shown below:

– Air Permeability – 4;

– Watertightness – 9A;

– Wind Resistance – C3;

In application of standards NF EN 12207, NF EN 12208, NF EN 12210, NF P20-302, NF EN 13115 and NF EN 14351-1+A2 specifying the classifications of windows and balcony-doors subject to the tests defined by standards NF P 20-501, NF EN 1026, NF EN 1027, NF EN 12211, NF EN 12046 and NF EN 14351-1+A2. For CE marking, the area of direct applicability of these results must be determined in accordance with Appendix E of NF EN 14351-1+A2

Our MR 78 mm profile has also been tested in Portugal by the ITCONS technological institute of the University of Coimbra, with equally favorable results.
