Project Details: Sunflex bifold doors in Hertfordshire

The properties, characterized by their contemporary style, feature flat roofs and external cedar cladding. The design focuses on maximizing natural light, creating an expansive feel in each room. Large glazing elements are a key feature, underscoring the modern architectural approach.

The choice of the ultra-premium Sunflex folding sliding door system is ideal for this project, comprising four panel and three panel designs, opening to expansive patio areas.  Designed to provide functionality, light and space, the Sunflex bifold doors are powder coated in the ever-popular black RAL 9005 matt finish, feature low tracks and thresholds, providing a seamless transition to the bright and spacious patio areas.

As specialists in high-end glazing solutions, we are delighted to be involved in a prestigious and unique homebuilding project on the outskirts of Harpenden, Hertfordshire.

Installed to two contemporary dwellings in a countryside location, we’ve enhanced both homes with our premier windows and patio doors, comprising Sunflex bifold doors, Sunflex sliding doors, and Origin OW-80 windows.  Two ultra-modern, single-story cedar wood-clad homes perfectly showcase our reputation and expertise in enhancing luxury new builds with top-tier aluminium windows and doors.

Contemporary Sunflex bifolding doors and Sliding Doors

Sunflex folding sliding doors come with several unique features, starting with their ultra slim door mullion sightline of just 117mm.  With top-of-the-line components, styling and quality, these doors provide an effortless folding action.

Thermally insulated frames, a durable low-maintenance colour finish, and high-performance toughened safety glass with a soft-coat low-emissivity coating, warm edge spacer bars, and argon gas fill.  All these components work together to provide highly insulated, ultra-secure doors with minimalist style.

The specially designed panel catches ensure the doors can only be closed sequentially and safely.  The slimline designer door handles are another fantastic feature of Sunflex bifold doors, designed to line through with the door frames. This design provides clean glass lines inside and out.  Other bifold door systems have the lead door handles at a right angle.  The Sunflex design means no handle is visible through the glass.

Sunflex SVG Sliding Doors

Our best-selling Sunflex sliding doors collection comes in three sightline options, from an ultra-slim 20mm mullion, a 30mm option or an 83mm version designed for the larges possible sliding doors. The unique features of Sunflex doors a two or three panel design is their ability to open and park completely flush, maximizing the opening space. 

Also with a low track, this flush design creates seamless internal flooring and external patio slabs and all Sunflex doors come with light and smooth sliding action and minimalist styling, offering unobstructed views and easy access to outdoor spaces.

Origin OW-80 Windows – Enhancing Light and Space


The distinctive flush casement design of the luxurious Origin OW-80 aluminium window is perfect for this installation of contemporary glazing and its sightlines and styling works perfectly with the Sunflex bifold doors and sliding patio doors.

Designed as floor-to-ceiling picture windows, these have a top hung opener over a fixed pane beside a large, fixed panel.  The result is a large, focal-point window in each of the rooms, creating brighter interior and providing fantastic views to the outside spaces.

Origin windows come with first-class build quality, fit and finish. These too are coloured in RAL 9005 matt finish and glazed with toughened safety glass, equipped with low-emissivity coating, warm edge spacer bars, and argon gas fill. 

All windows come with the trusted Yale brand locking system, providing the best possible security, combined with the safety glass and the Origin window design and engineering that this brand is known for.
