Extremely popular in the European and multi-storey markets, tilt-and-turn windows are ultra secure, extremely versatile and can offer very large openings. Whether opened horizontally for increased cross flow or left vertically ajar for superior ventilation of built-up stuffy air at ceiling level, these Duo Glass double-glazed windows deliver the best of both worlds. Our tilt-turn handles come standard with key locking, and boast up to 9 locking points around each sash. Ask at your local showroom about our massive tilt/turn balcony door option.
