When Lidl Schweiz outgrew its main building in Weinfelden, Switzerland, a new twostory, headquarters was built right across the street with a glass facade.
To meet the Swiss Minergie requirements for sound insulation, construction ecology and daylight harvesting, Itten+Brechbühl AG chose Saflex Structural (DG41) PVB interlayer. It ensures structural strength and provides exceptional color neutrality. Specifying Saflex Structural was advantageous for reducing deflections and overall product weight and provided improved edge stability compared to regular PVB, which was essential for the exposed edges of the folded facade design. Plus, it has broader compatibility with frit/coating.
Since the two upper levels house office space in an open-concept design encased in a glass facade, it was important that the windowpanes met sound insulation requirements for acoustics. It also ensures that occupants can take advantage of natural light.
