System Description
With the AKOTHERM hidden vent window system, viewed from the outside the sash is completely hidden by the frame. This ensures an absolutely homogeneous look and gives you creative leeway, particularly when installed in the AKOTHERM facade constructions.
The corner connectors can be pressed/pinned together using corner brackets. All standard hardware such as turn, turn/tilt and tilt can be incorporated in the AT 740 SI system.
