Interchangeable inserts for retrofitting

The cellar can fulfil varied functions in modern residential buildings. It can be a living area, utility room, office or heating room, junk room, bicycle cellar. The requirements for the window can be very different, just like the room use. The ACO Therm® 3.0 is the first choice for the former stated use. The second stated use is an unheated cellar. ACO provides the Therm® 1.2 reveal window for utilisation in these rooms. The window is equipped with either a tilting casement or a steel rotary casement insert especially for the use in cold cellars.
