Eco System® 50 is a well-insulated system for windows and doors, that combines aesthetic design and energy efficiency with a moderate price. The system’s HI+ variant achieves Uf values down to 1.6 W/m²K. The Uf of a frame/vent section with 86 mm visible width is 2.3 W/m²K. The system’s limited built-in depth allows its application in many constructions, even with reduced wall thicknesses. Design wise, ES 50 offers, next to the functional design frames, special block profiles resembling wooden frames. The use of invisible fittings results in an even more elegant look, since hinges are no longer in sight. In addition, ES 50 can comply with burglar resistance class 2, offering a safe and secure solution both for residential constructions and utility buildi

MIX Paper from responsible sources FSC* C007370 This table shows possible classes and values of performances. The values indicated in red are the ones relevant to this system. (1) The Uf-value measures the heat flow. The lower the Uf-value, the better the thermal insulation of the frame. (2) The sound reduction index (Rw) measures the capacity of the sound reduction performance of the frame. (3) The air tightness test measures the volume of air that would pass through a closed window at a certain air pressure. (4) The water tightness testing involves applying a uniform water spray at increasing...
