Thermeco's Tilt and Turn windows have a dual function - they can turn like a casement window or tilt like a bottom hung window. They can also open at the top with special hardware. The casement function allows for a 100% opening providing maximum ventilation. During rain, the tilt function prevents water coming in while still offering ventilation. These windows feature European technology multi-point locks for added security and excellent weather sealing. They are lockable from the inside and can be keyed. Tilt and turn windows offer easy cleaning on both sides. Fixed flyscreens can be installed on the outside and detachable handles are available for use in public places.
