FAQs
In the 76 MD Zero system, the sash is completely covered by the frame from the outside. From the street, the window looks like fixed glazing, even if it opens. This allows architects to create facades with clean, symmetrical lines where no difference is visible between opening and fixed windows.
Because the sash profile is "hidden," the visible plastic part is reduced to a minimum. This increases the transparent glazing area by approximately 15-20%. Your home is filled with natural light, which is especially valuable for small rooms or spaces with sea or garden views.
This is the main purpose of creating 76 MD Zero. It perfectly combines with High-tech and Minimalist styles. The narrow, straight profile lines emphasize the modern character of the building. It is often chosen for premium villas and apartments where design is a priority along with functionality.
Not at all. Zero is based on the proven 6-chamber 76 MD platform with three sealing circuits. The profile heat transfer coefficient is around 1.0 W/m²K. You get an ultra-modern appearance without any compromises on heat or cold protection.
Cleaning 76 MD Zero windows is no different from standard systems. In the open position, all surfaces are accessible for cleaning. Moreover, the absence of protruding sash parts outside reduces the number of places where street dust and dirt can accumulate, making the facade neater.
The system is fully compatible with modern hardware systems, including fully concealed hinges. In this combination, the window looks maximally aesthetic both from outside and inside — there are no protruding elements on the frame, only an elegant handle.
