SCHÜCO AWS 75 BLOCKSYSTEM SI + ALUMINUM WINDOWS, THIS IS A PURE FOCUS ON DESIGN AND PRODUCT LIFE SPAN

The most popular choice of narrow profile windows
This window system, known as the BlockSystem (BS), is the ideal choice if you prefer the maximum area of glass and thus use every centimeter for sunlight and the perfect view. Seeing is believing.
The narrowed frame sections are hidden and practically only a small part of the frame is visible. In terms of appearance, this system is both for design structural integrity. From the exterior side, the outer layer of insulation and plaster can be led to the edge of the frames. The resulting effect is that the number of visible aluminum frames is minimized and you can enjoy an unobstructed view.
Compared to the classic variant, the entire system is equipped with one additional standard seal. The windows from this system thus achieve a perfect seal. The maximum dimensions of one section are 1.5 m wide and 2.2 m high. Thus, a high degree of structural integrity level is ensured.
INTEGRATED SECURITY
A constant feeling of security. Schüco security is not just a good feeling, it’s a fact. With innovative technology, and while not visible functions beyond compare. Windows can be closed and locked automatically, even remotely via mobile phone or PC.
Safety according to Schüco standards is no coincidence, but the result of mature technologies that also include aesthetic aspects. After all, more safety should not be at the expense of design quality. The Schüco SimplySmart concealed fitting offers not only architectural freedom, but also a high degree of basic security. The installation of additional security locking elements can increase the burglary resistance of windows up to class 3 (RC3); see the security page for more information.
