The aluminum Sunflex sliding door range offers the ultimate combination of aesthetic appeal and advanced technology. We believe they are perfect for maximising the amount of natural light in your room whilst releasing the potential of your view.

Our Sunflex sliding door is ideal for larger openings where you can have much larger panels of glass and the Sunflex SVG30 (30mm sightlines) is packed with unique features to ensure the doors do not just look good, they perform time after time.

Designed with 30mm sightlines and no external reinforcing profiles, this true slim system has incredibly narrow frames no matter what angle you view it from. The versatile design allows for large panes of glass which are ideal for breaking down the boundaries between inside and outside. This Sunflex sliding door is no different to the other products they offer; the advanced security, versatile design and superior quality are all reflected through every step of the Sunflex journey.

Depending on the configuration you choose a twin or triple track, these tracks can be recessed into the floor to create a seamless connection between inside and outside. Crucially (and unlike other available systems on the market) this flush track does not reduce the weather tightness of the doors. This Sunflex system utilises highly engineered polyamide coated stainless steel carriages for smooth operation.

As standard Sunflex have 4 powder coated finished for you to choose from (Anthracite grey 7016 semi-gloss, Graphite Black 9011 matt, Slate grey 7015 matt and Traffic white 9016 semi-glass). If these do not quite meet your needs there are more than 200 Ral colours with a variety of specialist finished to perfectly compliment your home. There s even the option to have your Sunflex sliding door with a dual colour finish allowing you to match the internal and external faces of the frame to the inside and outside of your property.

Each system includes a continuous five-point lock including mushroom headed cam locks and an additional centre hook lock providing excellent security and the five-lever euro profile cylinder exceeded the requirements of British insurers. Anti-lift blocks prevent the panels being levered from the tracks making the old security concerns with sliding doors a thing of the past.

Amongst the most weather tight multi-track sliding systems available, the Sunflex sliding doors are independently tested to achieve up to: Class 7A (300Pa) water tightness, Class 3 (600Pa) air tightness and Class AE (2400Pa) wind loads. The doors are not just good at keeping wind and rain out; they also perform well at keeping heat in. Available with double or triple glazing the doors can achieve an overall U-value from just 1.4W/m2k with a glass upgrade.

This sliding door system has the unique ability to stack flush…

…with each pane of the system sliding completely behind the next. This is achieved because there is no requirement for external reinforcing to strengthen the square-edged frame of the door. You are able to take advantage of this feature when you have one fixed sash and the others sliding, thus providing a neat, tidy and contemporary appearance when the doors are completely opened.

The SVG30 is available with D-shaped handles, colour coded to match the frame of the doors. Alternatively you can upgrade to the stylish and hugely popular stainless steel feature handle for a modern and contemporary look or a recessed handle that is set near flush into the frame of the doors. If you would like the unique Sunflex flush stacking doors to have a recessed handle on the outside and your choice on the inside, many of our customers go for the stainless handle option.

With panel widths from 88mm up to 3m wide and heights of up to 2.8 for the SVG30, the doors can be tailored to your exact requirements. From single panels sliding into a pocket, all the way up to 24m wide openings on triple tracks; plus removable corner posts, flush stacking and panels sliding in more than one direction, the Sunflex sliding doors offer configuration options to meet the needs of almost any project.
