The optimized Schüco AWS 75.SI+ (Super Insulation) standard window system for the 2-15/16” (75 mm) basic depth is part of the Schüco AWS system platform and forms the basis for a range of applications in energy-efficient building envelopes. Depending on the architectural requirements, the highly thermally insulated aluminum system can be used as a punched opening, ribbon window, façade insert unit or in combination with Schüco door systems. An additional benefit for architects and specifiers is the wide range of opening types. A wide range of profiles is available within the system platform, including corner mullions, structural mullions, symmetrical and asymmetrical mullions, as well as a number of design variations and additional combination options, such as with Schüco sun shading and ventilation systems. Developed to be future-oriented, the system is based on the Cradle-to-Cradle (C2C) principle, making it perfect for planning sustainable building concepts with construction units that have been tested and assessed for harmful substances and recycling properties. Raw materials are turned into products which can be turned back into high-quality raw materials with their original quality at the end of their lifecycle. Schüco AWS 75.SI+ has been tested by EPEA Hamburg and certified with a silver label in accordance with the latest C2C standard of the American Cradle to Cradle Innovation Institute.
