Ultra Slim Bifold Doors – Slide and Pivot Door System

With more than 5,000 UK installations, our most popular doors during the past few years are our Ultra Slim bifold doors with aluminium frames of less than 2cm, finished in anthracite grey. Our slide and pivot system is similar to bifold doors but each of the door panels opens individually, eliminating the need for folding hinges.

Slimmest Bifolding Patio Doors: Maximum Access, Stunning Views

From the company that first delivered Slimline Aluminium Bi Folding Sliding Patio Doors in 2003, SunSeeker UltraSlim Slide and Turn Patio Doors have proved a winner…

UltraSlim is unrivalled with its slim sightlines: just 19mm of frame visible at the sides of each door. Putting this in perspective, our 6-door system has less frame to obstruct your view than the slimmest bifolding 3-door system from many other manufacturers. Individual Ultra Slim doors slide along the guide rails and turn to open, facilitating the widest opening for access.

Often referred to as retractable doors, slim bifold doors, or slide and pivot doors, slide and fold doors, folding sliding doors, slide and swing doors, slide and stack doors, or slide and turn doors, the Ultra Slim is our leading selling product since 2017.

A Contemporary Alternative to Slimline Bifold Doors

SunSeeker Ultra Slim slide and turn doors/slide and pivot doors are different. Why? Because they look like bi-folding doors when they are open and when they are closed, but they do not slide and fold. Instead, there is a main door that opens normally and each of the other doors will slide along the guides and pivot open, stacking at the side.

Additionally, unlike bi folding doors, you can slide each folding glass door along the guide and just leave it wherever you want to, leaving gaps between the doors to allow air flow through – for more examples, see our photo gallery.

Customisation Options for Ultra Slim Bifold Doors

At SunSeeker, we understand that every home is unique, and so are your requirements. That’s why we offer a range of customisation options for our UltraSlim bifold doors and windows, ensuring they complement your style and meet your needs perfectly.

Aluminium Frame Colours

Our standard sliding bifold door and window frame colours are anthracite grey (RAL 7016) and natural pure white (RAL 9010). However, if you desire something different, we offer the option to powder-coat aluminium door frames in a vast array of industry-standard RAL colours – up to 300 choices. This service is done in-house, guaranteeing high quality and durability. The finished frames are virtually maintenance-free, eliminating the need for painting or varnishing.

Glass Options

  • Laminated glass for added security
  • Argon-filled glass for improved insulation and thermal performance
  • Antisun glass to reduce glare
  • Obscured glass for privacy
  • Tinted glass for a stylish, modern look

Integral Blinds

For added convenience and aesthetic appeal, our integral blinds are a perfect addition to your slide and turn glass doors. These blinds are sealed within the double-glazed units, ensuring a dust-free environment. The benefits include no cleaning required, as they are protected from dust and damage. They offer superior sun shading compared to traditional blinds and improve thermal efficiency, contributing to better energy performance.

Uni-Blinds are available in two styles: venetian blinds with three colour options and pleated blinds in two colour choices. Both styles feature colour-coordinated components and white external controls. Additionally, an electrically operated system is available for even more convenience.

Ultra Slim Retractable Patio Doors

More contemporary than bi-folds, the UltraSlim slide and pivot system.

The SunSeeker UltraSlim system comprises individually sliding doors which can be spaced along the guides. The master door can be sited at either end and may depend on where the doors are to be sited as well as where you would like the master door to be situated and where the doors should stack when they are open. Our site surveyor will be able to advise you which system is more suitable to your home.

Slide and turn patio doors are fully retractable and look similar to slimline bifold doors when fully opened or closed; Ultra Slim aluminium door frames are considerably narrower each side of the glass than folding-sliding doors available from other UK manufacturers.

How have we managed this?

The team at SunSeeker Doors is continually developing ideas for door design to reflect lifestyle expectations of our customers. The UltraSlim aluminium frames of our slide and pivot patio doors were made possible due to the unique locking system we developed, as each door is lockable for added security. Slide and pivot doors are not required to be hinged together, as bifolding doors are.

Ultra Slim doors are all fully retractable, which means that when they are all open, they stack at right-angles at the side of the opening, maximising the access space between the two areas. Open or closed, our Ultra Slim stackable sliding glass doors offer great visibility and plenty of natural light.

Ultra Slim Bifold Doors FAQ

What is the difference between regular bi-fold doors and UltraSlim slide and pivot doors?

UltraSlim glass doors feature a slide and pivot system, where each panel slides individually along a track without the need for folding hinges. The panels can then be turned/pivoted 90 degrees at the side to fully open the system.

When fully closed or fully open, they look very similar to regular bifold patio doors, but with slimmer frames thanks to a lack of bulky hinges between each panel.

Ultra Slim Sliding Doors were the first in its class of fully retractable patio door with thin 19mm coated aluminium side frames and, therefore, more glass for viewing when doors are fully closed compared to traditional bi-fold doors. UltraSlim slide-and-pivot doors stack neatly to the side of the opening, making more space available to walk through from home to garden than with conventional sliding glass patio doors.

What makes Ultra Slim doors different from traditional patio doors?

Ultra Slim doors offer a unique blend of functionality and aesthetics that sets them apart from traditional patio doors. Unlike conventional sliding or French doors, our slide and stack glass doors combine the best features of bifolding patio doors and sliding patio doors. The Ultra Slim system uses a slide and pivot mechanism, allowing each panel to move independently along the track and then turn 90 degrees. This design eliminates the need for hinges between panels, resulting in sleeker frames and larger glass areas. When open, Ultra Slim doors stack neatly to one side, creating a wider, more accessible opening than standard sliding doors or patio bifold doors.

Can Ultra Slim bifold doors be used as internal room partitions?

Yes, our Ultra Slim aluminium bifold doors can be installed as internal doors/internal bifold partitions, such as between a house and a conservatory.

How can your slim bifold doors be customised?

We offer customisation options including a range of up to 300 RAL colours for the aluminium frames, various glass options (laminated, argon-filled, antisun, obscured, and tinted), and integral blinds in venetian or pleated styles. Our slim bifold doors are made-to-measure and many of our customers purchase multiple sets of doors (and often matching slide and pivot windows) for a unified look. A popular customised variant is our Georgian Patio Doors with Integral Bars. Please contact us if you have any other bespoke requirements not listed here.

Can Ultra Slim doors be installed in older properties?

Yes, Ultra Slim sliding stacking doors can be fitted in older properties, though some considerations may apply. Our stackable sliding doors are made to measure and designed to adapt to various architectural styles and structural conditions. Our experienced team can work with period features, ensuring your new slide and fold windows or doors complement the character of your home while providing modern benefits. The slim profile of our sliding stack doors often works well in traditional settings, offering a less intrusive look than bulkier alternatives. With proper planning and expert installation, Ultra Slim slide and stack doors can breathe new life into older properties.

How secure are the bi folding slide and pivot door systems?

Our UltraSlim stacking sliding glass doors are PAS 24 certified, featuring a unique locking system that ensures each door panel is secure. This provides peace of mind for your home’s security.

Can Ultra Slim doors be installed in garden rooms or outbuildings?

Ultra Slim slide and stack patio doors are an excellent choice for garden rooms, summerhouses and outbuildings, providing great views and practical, space-efficient access. For outbuildings like home offices or studios, stack and slide doors can create a flexible, inspiring environment that opens up completely on pleasant days. The thermal efficiency of Ultra Slim sliding pivot doors also helps regulate temperature in these often less-insulated structures.

What is the maximum width that your slim bifold doors accommodate?

Our Ultra Slim sliding doors are suitable for openings up to 10 metres wide. All doors stack neatly to the side, maximising access and creating a wide, unobstructed opening for stunning panoramic views.

Are the Ultra Slim bifold doors energy efficient?

Our external bifold slide and pivot doors and windows come with thermally broken aluminium frames and double glazed British Standard Kitemark K-glass as standard. Energy efficiency and thermal insulation can be improved even further with different glazing options at an extra cost.

Do slide and turn doors require much maintenance?

The aluminium frames of our Ultra Slim bifold doors are virtually maintenance-free. They do not require painting or varnishing, making our slide and turn aluminium doors a hassle-free choice for your home.

What glass options are available for the Ultra Slim bifold doors?

We offer several glass options for our slim bifold door systems, including laminated for security, argon-filled for insulation, antisun to reduce glare, obscured for privacy, and tinted glass for a modern aesthetic.

In addition to these slide and turn foldable sliding doors, SunSeeker Doors also offers Slimline Sliding Patio Doors and Frameless Glass Doors. Any of our bifold and pivot doors may also be installed as French Doors. The sliding patio doors consist of large sliding glass panels which slide on dual or triple tracks. These wider large glass leaf doors can provide up to 2.5m width of uninterrupted viewing per panel. Frameless glass doors are available single-glazed or double-glazed, for use as room dividers, outdoor enclosures, patio doors, and more.
