Introducing the slimmest patio doors

The perfect balance of minimalist and function in our new slimmest patio doors promises a unique look and a better overall door experience than a regular sliding or bifolding door. Introducing our Slimline slide and turn doors – narrow-profile patio doors designed to maximise your views and light entering your room.

Slimline patio doors – designed and made by Frameless Glass Curtains.

Inspired by our ultra-premium frameless doors, our new Slimline patio doors are designed with the same incredible aesthetics, quality and functionality but in a fully-framed alternative. At the same time, our new doors provide a distinctive door design you won’t find elsewhere.

Our doors start with cutting-edge design and are packed with the latest door technology, components and quality. We think there is no comparable patio door on the market, whether in terms or styling or its altogether different slide-and-turn design, that gives you a better overall door experience.

We’ve designed our new Slimline patio doors to work in any style of home, whether modern or more traditional and to fit any existing or new structural opening.

There are several unique features only available with a Slimline door.

The thinnest profile patio doors.

With a mullion sightline at a mere 60mm, our new Slimline patio doors are thinner than any bifold door and many standard sliding doors.

The look of a minimalist sliding door when closed and all the functionality of a bifold when fully opened.

More functional patio doors.

The innovative slide-and-turn design provides the best of all worlds. The inline nature of our doors ensures they don’t take up any space in a room, just like a sliding door.

Better than a bifold, you can place your garden or room furniture close up to the doors, giving you more space inside and out.

Designed for everyday use.

A traffic door comes as standard letting you open it just like a regular door for fast garden access without folding the remaining panels back.

The individual opening panel makes our doors functional and designed for everyday living, such as general ventilation, letting out your pet or taking out the washing.

Minimalist steel-look doors.

The already slim 60mm sightline and the set back frame make our new slimline patio doors distinctive when designed in the steel look.

Thin glazing bars create the industrial style, with the signature grid-like pattern and multiple panes of glass.

Slimline patio doors built to last.

Our doors are designed and engineered by us, built to an exceptional standard and promise to be beautiful and last. We’ve tested our doors to the latest PAS 24 security requirements, and they’ve also passed testing for air and wind resistance. Thermally insulated frames combine with our high-specification insulated glass units to give you excellent thermal performance and help lower your energy bills.

Bespoke to your precise sizes, configuration and colour, you can choose a single or double-door set or from three panels in our innovative slide-and-turn design. The opening and closing action provides a better experience than regular bifolds, with added ventilation and a user experience that we think is far superior to other types of doors with a similar opening action.

With no intermediate handles or door hinges, our new slimline patio doors come with just one modern and multifunctional handle. Unlocking the doors starts with the key cylinder, and rotating the handle releases the primary door also acting as the previously mentioned traffic door. Once opened, the remaining door panels are free to slide partially along the track for ventilation or to the end of the track to swing and stack fully open. The reverse procedure closes the doors, and the final closing action via the handle compresses the panel for excellent weather protection. A multipoint locking system and security cylinder with keys come as standard.

Designed better than standard bifold doors

Every detail of our new slimline patio doors, designed and made by FGC, promises the latest generation design that we think gives you a better experience than a regular bifold door. Here’s how they compare to one of the leading brands in terms of slim profiles and overall sightlines.

Choose your design, opening configuration and colour.

You can use our new slimline patio doors to replace any dated door in an existing opening. Or we can help you design the perfect door for your new extension or building project.

The door design can be configured to open in or out. You can choose a fixed or corner design from two panels up to eight or more. Adding colour-matched aluminium bars creates a desirable industrial or steel look, and there is even a lower set threshold option, giving a smooth and uninterrupted flow to your patio area, with no loss of weather protection.

FGC’s slimline patio door specifications.

The advanced glass comprises clear toughened safety glass, Argon gas fill and Planitherm 1, achieving U-Values as low as 1.2Wm2K with a double glazed unit and an impressive 0.8Wm2K with enhanced triple glass.

When uptraded to laminated glass our doors have passed PAS24:2022 securing testing.

Panel sizes of up to 1000mm wide and up to 2500mm high.

60mm sightline between the individual panes, consisting of 2 x 26mm aluminium profiles on each door and an 8mm grey PVC bubble gasket.

Frame head face dimension of 117mm, standard bottom frame face dimension of 124mm, side frame face dimension of 113mm. The low threshold option creates a threshold height of just 5mm.

A steel-look version is available using 31mm astragal bars.

Sophisticated ultra-slim patio doors by FGC.

Launched at Grand Designs 2023, our new ultra-slim patio doors were arguably the most distinctive, unique and innovative door product at the show.

Our new Slimline patio doors create an altogether different patio door experience, with an improved view and virtually no visible frame bulk, designed to connect to your garden better than a sliding or a folding door. You can also complement your new doors with our other contemporary glazing solutions, including internal glass doors and partitions and balcony enclosures.

Our small job was handled extremely professionally from start to finish and we are very pleased with the results.
Very happy with the service I have received, everything went smoothly no issues, I was kept up to date throughout the process and the fitting team were very professional, polite and friendly I would recommend fgc to anyone thank you
Amazing service, great aftercare, incredible product. It was hard to find something that would fit in our house and would have been pleasing to the eye aswell as stylish and modern and unique.From sales to install was smooth and stress free amazing bunch of people to work with I had a great experience
Great product with diligent, professional staff from start to finish. Highly recommended.
Firstly I have to say a huge thank you to Paul the owner of FGC for being willing to take on the job of sorting out the extremely shoddy and poor installation of the Origin doors and windows fitted on my new build home, when it was built. And replacing the damaged gaskets. I had your guys with me for two days this week. What a breath of fresh air comparted to the people of originally installed my doors and windows. Extremely professional and lovely chaps. They worked tirelessly to sort out the many issues we had. Would absolutely recommend 100% THANK YOU !
Response from the owner: Good Morning Paul, Thank you for taking the time to share your positive experience with us. We are absolutely delighted to receive it and are pleased we were able to resolve the issues for you. It’s been a pleasure working with you. If you have any further need in the future, please do not hesitate to contact us.
Very helpful and good communication, great product. Thank you.
Very happy with doors. Look great. The installation was quick and straightforward.Will recommend
FGC were brilliant. Great advice on the best windows to get. Extremely good installation. Always ready to solve any installation or manufacturing issues. We are extremely happy with the end result!
Frameless windows were brilliant, Liam Alfie and James were great, polite, courteous, and left the site clean and tidy. The windows look amazing, Great service from start to finish. Many Thanks
We love these doors and look forward to having them open a bit more once the patio has ben completed. They really have a "wow" factor and this becomes a double "wow" when people are shown how the corner can be completely opened up. It was about a year from my first enquiry to the doors being installed as there was a considerable amount of building work required to prepare the room. throughout this period I remained in touch with FGC and the service was exceptional. The installation team was on site for a day, starting early and working through to completion before driving back to Kent!! We have been really pleased with the standard of workmanship and even had compliments from other tradesmen working on the room (most of whom had never seen doors like this). These are expensive doors but the price difference from a normal set of bi-folds was well worth it for the uninterrupted view you get. The doors were installed in February but I have held off doing the review until the room was more finished so I could post a more representative picture. Once the patio is done the look will be even better than we originally envisaged. I have attached a few pictures of the room (the white table is only a temporary measure while we wait for the new coffee table).
From first contact to installation, my interactions with FGC have been easy, fast and professional. The end product is superb, we are so happy with our new doors - wish we had done this years ago. Well done FGC!!
This is the second time we have installed FGC and we are very happy with our second installation- very sleek and stylish and all staff very helpful, thanks
Frameless Glass Curtains have few competitors so they could take a lax approach to their work. However, that is not the case. We have had a porch installed in a space that was not square or aligned. The service from survey to finish has been above standard. Barry’s attention to detail and determination that the work would not be complete until his high standards were met was much appreciated. The communication from the admin side was clear and helpful. So all in all we will be using Frameless Glass again and have no hesitation in recommending them.
Brilliant product, what a difference, no frames to block our view of the Brecon Beacons. The service has been the best I think I have ever received and the fitting team were faultless - they travelled 5 hours to get to us in Wales, arriving 30 minutes early, working flat out without a break for 9 hours before driving 5 hours back, all without one complaint!!
Ordered Crittal-style French doors in aluminium. The doors look fantastic and are so much better than the ancient sliding doors I had before. The company were very friendly and easy to deal with. They were understanding of my delays due to a flood. The installers were professional and polite and poor things had to work on the hottest day of the year. Would definitely recommend FGC.
Really great service from this family run company. We love the doors and the install was top notch. Thanks!
Great service and amazing finish! Would highly recommend!
Highly competent office and site staff, great product and at a fair price. Couldn't be happier with the entire experience and end result.
From the beginning to the end, everyone at FGC have been amazing. I knew straight away that the glazing FGC would provide and install would be spectacular and how right that was! The FGC glazing allows our Edwardian stained glass door to still be a main feature and in fact it shows it off perfectly. We are so happy with the end result and can’t praise FGC highly enough, somehow 5 stars doesn’t seem to be high enough.
Their windows are second to none. No other company in Germany, UK or anywhere else can produce such a fabulous product.Any issues that has come up, they always come & fix it. The staff are so nice and polite. For a small company they do really a great job over all. The main things are the frameless bifolds that you hardly have any frame in the line of vision and there is a 5 years guarantee. Mr & Mrs Jahedi
Delighted with our new frameless glass doors. Had lots of lovely comments, even all the trades who have been working on our house have said they've not seen anything like them. Great having something a little unusual. The quality of the doors is of a very high standard. The service from FGC has been very good too, from ordering through to installation. All went very smoothly with no problems. Paid a bit more than regular bifolds, but worth every penny. Best decision, no regrets at all.
Great service and very welcoming for my father and I. Adrian in particular was very efficient, gave great pertinent advice and guidance on my future purchase!
Excellent in all aspects from initial viewing in showroom to actual installation.
Excellent service and product from FGC.I have a glass-box conservatory, built with structural glass about 20 years ago. The 2 sliding doors needed replacing, along with 2 side panels, and I contacted dozens of companies selling conservatory doors and none of them were prepared to install their doors because of the perceived risks of working with structural glass.Then I found FGC who, with no fuss at all, carried out a survey, provided a very reasonable quote for the doors/panels and then installed the doors/panels on the agreed date.Communication with the FGC office was always quick and easy. The surveyor and installation team were efficient and courteous. The product works beautifully.We can now use our conservatory again. Thanks FGC.
Great company with excellent, friendly and responsive service, the guys were helpful and efficient with the installation and the slide and turn doors are a fantastic product.
Fantastic service from start to finish, from the surveying, contact with office to the workmen. I have experience through work of a number of companies providing similar products and these guys have been by far the best to deal with
FGC installed a two-panel frameless glass door at our property yesterday. Wow!! the installation is exactly as discussed, and was carried out by two of FGC's team members who were so professional and courteous. They were excellent, and we have no hesitation in recommending FGC and their team to anyone considering such an installation.We are delighted with the installation, and very pleased we chose FGC.Well done FGC!!
The quality of the windows / doors are second to none.The customer service was first class from placing the order to installation we were kept informed at every step.The installation team led by Richard left our house and patio cleaner than when they arrivedI would recommend FGC 100%Tony- Burnley
From start to finish everything was excellent.Fab u lasThank you
We purchased a beautiful Origin sliding door and side window from FGC. FGC installed the sliding door and window on time, however the sliding door did not fit correctly. Issues can happen. FGC made the process of re-surveying and re-installation very simple. FGC is a very pleasant and professional company to deal with. We are very happy with their service and would strongly recommend them.
I love my doors! It’s transformed my place. The people are great, no nonsense, organised and efficient. I’d recommend them to anyone
Excellent planning and product advice. All the staff were polite courteous and friendly.On the day of the installation, the team arrived bang on time -we live in Wales so a long drive from Kent! They had the job done by lunchtime (fitting a sliding patio door) and I have to say that on first impression of the unit, it looks and feels like solid quality.
We had a 5m stretch of these wonderful doors installed several years ago and have been very happy with the uninterrupted view of the garden that they allow from the living room. They are admired by every tradesman who sees them. A minor problem we experienced with water ingress last year was promptly and effectively resolved, and the doors were serviced for free at the same time.
Response from the owner: Hello Ian, thank you very much for leaving us a review and glad you're happy with your doors and our service.
Great staff and great products! Have visited the showroom to view doors, really loved all of them! Have referred to a friend - Can't recommend enough
Really great doors. Really are something different. Expensive, but you really pay for what you get here.

What our customers say

I am very happy with the doors – I saw them last night after work – though I didn’t open them as I wanted to make sure I followed the installers’ instructions not to. They look wonderful and my boyfriend and mum tell me they were absolutely lovely chaps. The finish seems brilliant and appears to be a huge improvement on the last installation. Ms Warren, London

Delighted with final result and extremely pleased that I decided on these ‘frameless glass doors’ over conventional bifolds. The company had no end of patience with any pre-order questions that I raised and the factory visit and visit to view an existing installation were very informative and reassuring. The team that fitted were professional, attentive and extremely competent and the final result excellent and much admired. Thank you. I would not hesitate to recommend the

As to how we were from initial contact (were we polite)? Staff were polite and prompt in answering telephone questions. There were technical problems with our installation and staff were open and discussed options and were polite. The fitters were surprised at the distance they had to travel to reach us each time, although we had explained where we lived prior to proceeding with the installation to check whether the company would be happy to

When we purchased our house, it had two sets of timber bi fold doors, each spanning an opening of approx. 5m. These caused us a lot of problems with warping through the seasons, and the ration of timber to glass limited the light into the rooms. We therefore replaced them with the frameless curtain system and could not have been happier. We could only be bothered with the faff of struggling to open the timber

Our windows look great and certainly get the wow factor with visitors… Fitters were great, polite, very quick very tidy and helpful in advice. Yes we would recommend..

FGC fitters Mick and Baz arrived at 0754hr ready to begin work. They were polite, helpful and fitted in seamlessly with the existing project team responsible for the restoration of this significant village property. The boys worked without fuss, cheerful with a ‘can do’ attitude taking the time to explain the system as they fitted it. The house belongs to Simon Menzies an old friend from the Army, he and his wife were not present,

I would like to reiterate that we are very pleased with our new FGC doors. As a Chartered Building Surveyor I was impressed with the installers who were careful, methodical and very professional my wife who is most particular was also very impressed with their cleanliness. I am sure we will get many years of use from this wonderful addition to our home. Mr Martin – Portsmouth Update: I have already provided a review of

We used FGC to manufacture and install frameless glass doors on all three sides of a large terrace bay. The design was complex and required a flexible and innovative approach to their existing designs. The result was outstanding – clear uninterrupted views over the countryside and a flexible opening pattern which allows fresh air no matter the weather. FGC worked well with the architects and builders on this major project and have provided a responsive

Thank you again for the doors, we’re very happy with them and, once the renderer has finished (hopefully tomorrow), we’re really looking forward to removing the plastic protection so we can see through them properly. Mr B,

I have to say that although I was not on site to see the finished result, the photographs of the work is remarkable and to add to that compliment, our master builder Chris Seviour reported back to me yesterday that he was so impressed with your team and with the final result. Thank you all for such a tremendous job – I’m hoping to have an article written in Country Living about the house later

Claire Menzies

Basically the installation itself was done pretty quickly and efficiently – three guys turned up early in the morning and were done by lunchtime. Polite, tidy.
