    The Stellar Lift & Slide Patio Door has the slimmest sections and its lift and slide patio design with a wider glass area, delivering the coveted light and airy feel, alongside pared-back, clean aesthetics.

    The unique gearing enables the opening sash to be semi-locked at any point and easy, smooth gliding of doors. With a sliding door, the quality of the engineering is paramount. Stellar’s patio doors incorporate Lift and Slide technology. ‘Lift’ simply means that there’s a built-in system which takes some of the weight when you’re opening the panes. This allows the panes to glide smoothly and easily along their tracks. You can have a sliding door with larger panes, and there will be fewer vertical frames to interrupt the view.
