Project Details: SF60 Sliding doors in St Albans.


The property is a modern redbrick construction with a dark grey tiled roof and aluminium windows throughout, perfectly blending with the elegant and minimal design of the SUNFLEX SF60 sliding doors. The extension features an ultra-sleek kitchen with carefully chosen modern lighting, flooring, décor, and accessories. Two near-frameless rooflights above the dining area and kitchen flood the space with natural light, enhancing the open-plan feel.

Before approaching us, the homeowners had a less-than-ideal experience with a previous installation where, unfortunately, the doors weren’t fit for purpose, nor were they fitted correctly. We took the time to understand their needs in detail, ensuring they received exactly what they wanted the second time. Our expertise and knowledge allowed us to solve the design and functional issues they previously faced.


As Sunflex Gold Partners and fully trained, accredited and approved Sunflex sliding door installers, we are delighted to be among the first to install the new Sunflex SF60 sliding doors in a contemporary detached house in St Albans, Hertfordshire. 

This ultra-premium and sophisticated sliding door is a cutting-edge addition to the premium sliding door market, and we’re proud to offer our clients the exceptional benefits of this innovative product.

Our Solution: SUNFLEX SF60 Sliding Doors


We recommended the SUNFLEX SF60 aluminium sliding doors, finished in jet black, to complement the home’s aesthetic. The SF60 is one of the most advanced sliding door systems on the market, known for its exceptional design, thermal efficiency, and innovative features. 

With such high-tech design also comes innovation. Other sliding doors of this type rely on a bonded glass construction. Bonded sliding doors are more complex to manufacture, harder to handle and transport and more challenging to install. SF60 sliding doors are dry-glazed, meaning internal glazing beads hold the glass units in place. This allows for easy replacement and provides peace of mind for years.

Style is at the heart of every sliding door in the HBD collection, and Sunflex SF60 is no exception. Slim sightlines were required on this St. Albans house, and the SF60 has just 30mm visible and finish flush with the glass.

The three-panel design offers the fantastic ability to open from either the left or right-hand side. Depending on our customer’s needs, they can enjoy a two-thirds opening on either side, with panels neatly stacked opposite. This flexibility is perfect for the dining table close to the doors. For example, on warm but windy days, the doors can be opened and parked in front of the dining table, providing shelter from the wind while allowing warmth and an open aspect.

A flush threshold is essential for installations like this, creating a seamless transition between indoor 
and outdoor spaces while providing complete weather protection. The project images show that the doors work harmoniously with additional drainage outside, ensuring the track remains weather- sealed and functional in all conditions. The advanced design of the track differs from other sliding door systems where the rollers visibly sit on top of the track. On all Sunflex doors, the wheels sit below the track, less prone to damage or debris, and always ensure smooth transitional movement of the door panels.

One of the standout features of the SF60 is its exclusive CUBIC handle design. Custom-designed for SUNFLEX, the handle features a contemporary appearance with square sections. The rotating top section ensures the door maintains the same neat look, open or closed. The minimalist design sits neatly within the frame’s width, drawing attention to the view beyond rather than the hardware. The flush and integral handles are designed so that the doors remain effortless to open and close.
