Contemporary narrow-framed, glazed sliding doors

With their ability to accommodate large glass panels combined with incredibly thin frames, aluminium sliding doors are a must-have for anyone looking to fill their extension, renovation or self-build with natural light.

With an exclusive choice of 20mm, 30mm or 83mm sightlines and every set of doors handmade to your exact specification, our SUNFLEX UK aluminium sliding doors can be tailored to your exact requirements – whatever the size and scope of your project.

When closed, sliding patio doors create a wall of glass, making the most of a view out and almost connecting the house and garden. Yet when open, they can provide a seamless transition between house and patio.

With individual panels up to 3 metres wide and overall systems up to an incredible 24 metres, the SUNFLEX UK range of aluminium sliding glass doors are a giant of the market, and thanks to their innovative design and advanced engineering, they remain almost effortless to operate even at the largest sizes.

  • A choice of sightlines Opt for our brand new SVG20 with incredibly slim 20mm sightlines, our exclusive SVG30 with narrow 30mm frames or choose the SVG83 with slender 83mm interlocks for a truly high performance sliding door system.
  • Style and performance Like every SUNFLEX UK product, our range of sliding doors are made not just to look good, but to provide effortless usability day-after-day and year-after-year.
  • Effortless operation With highly engineered stainless steel running carriages that make light work of even the largest panel sizes, the days of heavy to operate ‘patio-doors’ of the past are a distant memory.
  • Severe weather rating Designed to provide advanced protection from wind and rain, our sliding doors are independently tested to severe weather rating performance, making them ideal for even the most exposed locations.
  • Security as standard With a continuous 5-point lock on the lead door and PAS 24:2016 and Secured by Design™ standard security hardware included on all doors, our sliding doors provide advanced security as standard.
  • Slim from any angle With no requirement for ugly and bulky reinforcing to strengthen the frame, our sliding doors have narrow frame depths of just 59mm, ensuring they appear slim whichever angle they are viewed at - not just from straight on.

Why choose sliding doors?

With large glass panels and minimal frames, sliding doors are perfectly suited for extension, renovations and new build homes, particularly those with openings over 4 metres wide. The narrow sightlines enable the amount of glass to be maximised, ideal for making the most of the view or for increasing the amount of light you let in. Sliding doors are available in a range of configurations, from single panels sliding into a pocket up to 8-panel sets that transform an entire elevation.

Weather and thermal performance

Whilst the large glass panels of the SUNFLEX UK range of sliding doors help bring the outside in, there are times when it is beneficial to keep the outside weather out. Our sliding doors are independently tested to severe weather rating standards, achieving Class 3 for air permeability to provide advanced protection from drafts and rain. The doors can also achieve a wind load of up to 2400 Pa ensuring they are suitable for even the most exposed locations.

Our sliding doors also provide advanced thermal performance, achieving low U-values from just 1.2W/m²K double glazed to protection from heat-loss that far exceeds the requirements of Building Regulations.
