We build both vertical and horizontal pivot windows. Typical applications for pivot windows are large sized openings in commercial or residential buildings where the design calls for an unobstructed view and large window sizes (e.g. view property). Our pivot windows are easy to reach from the inside for cleaning and maintenance because the sash rotates 180 degrees. Pivot windows offer draft-free ventilation when opened in the preset ventilation position. Key Features: For operable sash sizes up to 116" wide and 87" high (horizontal pivot). For operable sash sizes up to 66" wide and 96" high (vertical pivot). High security and energy efficiency due to multi-point locking hardware (G-U Hardware, closing pressure adjustable). Easy installation due to easily removable sash. Solid construction, due to 2 3/8" thick sash and frame, with double mortise-and-tenon joinery. High energy efficiency due to double overlay sash construction. Easy and effortless to operate due to unique German designed pivot hinge system (G-U).
