The stand-out convenience feature of our Patio "Lift & Slide" door is the extremely simple movement of large and heavy doors. The space-saving opening of balcony doors with Lift & Slide sashes permits optimum use of space, as no sashes project into the room. Thanks to the generous door dimensions, plenty of light can enter the room which, together with the refined design, gives discerning customers a feeling of well-being. Lift & Slide doors allow barrier-free access to terraces or balconies, and can also be used just as room dividers. Besides being used in hotels and catering establishments, our Lift & Slide systems are also very popular in private home construction. Concealed night ventilation: Rotating the door handle upwards opens only the upper seal, allowing simple yet efficient ventilation that's not visible from outside ï¿½ the sliding doors remain fully locked and neither rain nor dirt nor insects can enter.
