This modern detached house is the first certified passive building in Soto del Real to the north of Madrid. By applying the principles of the Passive House Standard, it was possible to construct a functional and energy-efficient home. The planning process was heavily driven by a bioclimatic design approach. For example, the building’s orientation and the optimum use of natural light help keep its environmental impact and energy consumption to a minimum. When choosing the building elements, particular attention was paid to quality and professional installation. The plastic windows and lift-and-slide doors boast a high-quality design and function perfectly, the all-glass appearance of the frame-overlapping Nova-line windows going hand in hand with triple glazing. They have also been tested to meet the RC2 security standard. The classic lines of our FIN-Slide lift-and-slide doors add a relaxed touch to the modern, rectangular building. The level of insulation is maximised by the plastic core.All windows are equipped with SWISSPACER.
