GAULHOFER lift and slide patio doors create a panoramic window to your outside world. With GAULHOFER lift and slide doors, large glass surfaces are now a reality. Generous construction depths provide strength without compromising on thermal efficiency. Easy Opening One would naturally think that a door with a heavyweight frame designed to hold a larger than standard glass pane, would be difficult to open. However, the lift and slide door from GAULHOFER opens with the slightest touch. This is because the door opens onto a set of carefully concealed rollers which allows it to glide open effortlessly. Inline Lift and Slide If you’re looking for even less frame and more glass GAULHOFER’S new INLINE lift and slide door system provides one of the smallest profiles available in the market today.
