Thermeco's bottom hung windows tilt in and open at the top. They have concealed hinges at the bottom. During rains, the tilt function prevents water entering while still allowing ventilation. A choice of latch handle or pull bar is available. These windows feature European technology multi-point locks for added security and excellent weather sealing. Latch handles are lockable from the inside and they can be keyed. There is no compromise in security when opened in tilt mode. Thermeco's heavy-duty hinges and profiles allow for larger openings and weight capacity per sash (maximum width 1500mm x height 2200mm & weight 100kgs). Flyscreens can be installed on the outside.
