The SPEZIAL window system is a typical tilt window, with a special purpose of use in cellars, garages and utility rooms, due to its extremely narrow structure. This particular feature enables to provide the hardware made of a corrosion-resistant polyamide. The window closed, the hardware becomes an integral part of the system, the advantage being that not only the surface is saved while complete window elements are transported and stored, but also the even surfaces avoid occurence of damages. The assembly and cross-section of three-chambered casing is identical as the one appearing with the highly-valued SUPER system. Hence, it is possible to have the wings replaced without any problem later on, as when you e.g. intend to redesign the space's purpose, without the need for the casing to be dismantled whatsoever.
