The installation depth of 85 mm, 6-chamber profile, potential glazing up to the width of 48 mm as well as a unique middle gasket ensure perfect thermal insulation of the profile. The introduction of an additional middle gasket, which seals up the window construction on its circumference, results in the creation of the so-called dry chamber where the fitting system operates. Separating the mechanism from the external conditions contributes significantly to lengthening their operating time.
The low profile combination with the width of 115 mm makes it possible to enlarge the glass surface and, as a result, lets more light into the room.
