54 OPEN is OTIIMA's cold climate operable window system, offered in both inward and outward opening configurations. It is designed to accept triple-pane glass and offers multi-point locking for increased security. Concealed motorization is available upon request.

 

Available configurations include inward-opening hopper, tilt and turn windows (dual functionality) and outward-opening awning and casement windows. Each window type can be mulled to fixed windows, other venting windows, or window-walls for facade applications. Curved (radius) and sloped/leaning units are also available upon request.
