Aluminium Hybrid Patio Doors
Lift and slide doors
A well-designed sliding patio door can be a thing of beauty. The proportions are just right, and the frame doesn’t dominate. The panes glide smoothly along their tracks, but when closed, the doors are reassuringly secure. The wind can howl but there’s no trace of a draught and you can stand indoors on a frosty morning without feeling the chill.
The streamlined style hides engineering that makes these sliding doors safe, easy to open and easy to secure. It’s packed with technology that insulates a home. Its weatherseals are effective and long-lasting.
When you’re choosing to have feature glazing – that gorgeous wall of glass – your view will be interrupted by the vertical frame that marks the edge of each pane. If you reduce the number of panes, your view is better. One of the benefits of a sliding door is that each pane can be larger than on a bifolding door. It’s simply a matter of weight and glass can be surprisingly heavy.
Hardware is a crucial part of any sliding door, and Crystal’s lift and slide doors boast some of the very best with four locking points on the gearing. ‘Lift’ simply means that there’s a built-in system designed to take some of the weight when you’re opening the panes. It makes them glide more freely along their tracks. With its incredibly slim profiles and interlock options as low as 50mm, it makes the most of the glass area, delivering the coveted light and airy feel and clean aesthetics.
