The minimalistic design of  The Horizon window system leaves only the frame, glass and handles visible. The fittings are concealed and perfectly matched. Because the posts are only 25 mm wide and close flush with the casements, the elegant window module lets in a huge amount of light. There is a choice between inward opening windows and tilt and turn windows. When the casement windows are fully opened, the construction is supported by automatic positioning to ensure greater safety.
