In the F4 Thermo folding glass doors (as in the other systems of the F4 series) it is possible to install shading blinds inside the double glazing. At the same time, a special proposal that gives a distinct style is the use of horizontal aluminum profiles within the glass panel, so as to create the image of rectangular frames (divided windows).
