The Classic series does not only offer the possibility of large-area glazing but fills the gap to standard horizontally pivoted windows. The casement can be easily shifted and provides a clear view with no bothersome window frames.
The standard design of the Classic series allows installation of large areas of glazing. The elongated guide rails mean the window casement can be slid almost completely over the roofing. These windows are also very popular as roof exits or light domes.
Used as balcony exits, the windows provide new construction possibilities. The sliding roof windows are supplied according to the latest heat insulation ordinance of 2009.
