Breaking down the barrier between inside and out does not always mean losing your home’s ability to keep in the warm.

That is why SUNFLEX have made sure the thermal performance on each system exceeds the requirements of modern building regulations and even the incoming Future Homes Standard.

For sliding doors the highly advanced, German designed SUNFLEX SF80 achieves U-values as low as 0.8W/m²K, whilst for bifold doors the triple glazed SF75e matches that performance – making it the most advanced aluminium folding door system on the market.

Maintaining complete control over the fabrication of our systems and the components that are used are what allow SUNFLEX UK products to set the standard for quality and performance.

Every system we sell is manufactured in a SUNFLEX factory, either here in the UK or in Germany, by dedicated and experienced fabricators.

We aren’t reliant on third parties so have total control of not just the finished product, but also the materials, manufacturing processes and quality standards that ensure exceptional performance and reliability for years to come.

A perfect way to divide up an open plan living space is with the SUNFLEX internal glass partitions.

Our extensive range features systems like the frameless SF20 and Art Deco style SF22 sliding doors, providing homeowners the ability to enjoy an open plan space with the option to close their space off when required.

Each door is customised to your recommendations with bespoke options like open corners or panels that slide into a pocket in the wall making them truly unique to your design.

At SUNFLEX UK we have continually updated and evolved our products over the decades to meet the requirements of homeowners, developing systems with slimmer frames and profiles to bring in the most natural light to homes.

The SVG20 sliding door system for example features sightlines that are just 20mm wide, making the most of the huge panel sizes the system offers and almost uninterrupted views out.

Even our most thermally advanced sliding door the SF80 is made with just 30mm frames, removing the need for chunky profile that other door ultra-efficient systems have traditionally been designed with.

Both the SVG20 and SF80 are also manufactured with no ugly external reinforcing fins or profile, meaning the doors look slim from any angle and not just when viewed straight-on.

Having chosen your sliding door, SUNFLEX UK offers a further step of customisation: handles.

The SVG20 and SVG30 sliding doors are available with a range of handle options, choose from stainless steel or opt for a handle that is colour matched to the frame of the door to help maintain a consistent look throughout.

Our Trade Account Manager Will Mitchell explores the customisation options available and how they can be tailored for your system’s needs.

The Barrels is a beautifully transformed luxury holiday cottage, reimagined as a stylish escape on the Cornish coast at St Agnes

Originally a pair of mine-workers cottages, the renovation was sensitively designed by Ian Chalk Architects to create a single 5-bedroom property and at the heart of the first-floor extension is a spacious open-plan kitchen and dining area, featuring a striking full-height glass roof inset within the timber-clad structure.

Located in a World Heritage Site on a steep sloping site the house enjoys stunning views across Trevaunance Bay, that are perfectly framed by a two-panel SUNFLEX UK SVG30 sliding door, cleverly integrated with full-height glass-to-glass corner window to make the most of the panoramic vistas.

Supplied and fitted by Devonshire Windows, the versatility of the SVG30 system is perfectly highlighted by this installation which also features a completely flush floor detail, creating a seamless connection between the living space and the patio terrace complete with hot tub.

At SUNFLEX UK, we pride ourselves on the quality and longevity of our products. That is why all our sliding door systems are manufactured with non-structurally bonded glazing.

This means if the worst were to happen and the glass fails or is accidentally damaged, the sealed unit could be removed and replaced without having to replace the whole panel including frame.

This ensures that homeowners who choose SUNFLEX UK doors still benefit from ultra-slim frames but also have long term peace of mind for their purchases.
