The reference point is the use of the W450 concealed wing model, the least visible aluminum possible, which offers a simple and elegant aesthetic effect, as well as the safety and functionality provided by the perimeter mechanism. Its contemporary architectural design is reflected not only by its modern appearance, but also by its minimum façade height of 72 mm, which maximizes visibility and also allows the maximum possible flow of natural light within the building. The use of 31.8 mm glass-reinforced polyamide provides Uf thermal insulation higher than 1.6 W/m²K, while specially designed EPDM seals and advanced environmental mechanism ensure absolute waterproofing and wind resistance.
