Sunflex vs Origin sliding doors – which is best?

At alühome, we provide some of the best sliding doors brands on the market. We’re often asked by customers comparing Sunflex vs Origin sliding doors, which is best? These two outstanding sliding patio doors products are excellent in their own way. If you’re trying to decide between the two, we’ve put together a helpful guide giving you the features and benefits of each product and why you might prefer one over the other. Sunflex and Origin are part of our overall patio doors collection available from alühome.

Sunflex vs Origin – the companies behind the products

article comparing Sunflex vs Origin  showing an open corner sliding door

We’ve got more information about the various brand names we’ve chosen as a business. The first similarity when comparing Sunflex vs Origin for your new sliding doors is that both companies only make their products and nobody else. This is quite different to suppliers of Aluk, Smart Systems, Cortizo, Reynaers and other big brands where there are many different factories making these brands.

Therefore, if wanting doors made by the company behind them matters in your buying decisions, both Origin and Sunflex are great choices. The advantage of a sole manufacturer is a consistent quality every time and knowing exactly who makes your doors.

Whilst both companies have been trading for many years are sound and reputable, the Sunflex product has been around longer. Origin introduced a sliding door product in addition to their outstanding folding sliding system, in 2019. The Sunflex range of sliding doors has been around longer, arguably more widely used and more tried and tested.

Sunflex vs Origin sliding doors – what is slimmest?

The outer frame sizes are quite similar on both door brands, but when it comes to the middle mullion, the Sunflex model with the 20mm mullion is the slimmest. The Origin OS-29 has a 29mm mullion, 1mm thinner than the SVG30 model, also available with Sunflex.

Only Sunflex doors give you flush stacking panels

A unique feature when comparing Sunflex vs Origin sliding doors is what you get with the doors fully open. Only Sunflex gives you flush stacking panels fully open. For some people, this is not a significant requirement, but it’s another advantage and gives you just that little bit more of your available clear opening.

More opening options with Sunflex sliding doors

Most sliding patio doors work with a familiar push-pull action. These are called inline sliding doors and both Sunflex and Origin sliders come in this option.

With Sunflex doors, there’s also a lift and slide operation. The difference between inline and lift and slide is how the doors move. Inline doors just push along their track after you’ve unlocked them. Lift and slide doors work via a rotating handle. After unlocking, rotating the handle raises the door panel a little, ready to slide as needed.

The significant advantage is you can set the door back down partially open and secure it.

Sunflex is the go-to door when you need an open corner design. Origin don’t offer this option with their sliding door product unless you go for the bonded model.

Finally, if the latest steel-look, heritage or industrial style is what you’d like, the Sunflex proportions make for a better version of this look compared with Origin.

Sunflex vs Origin – minimum and maximum sizes

Origin doors are perfect for standard size openings.

Origin doors go as small as 1463mm wide and up to 2600mm high

Sunflex doors go as small as 800mm wide and up to 3000mm high.

Both doors are therefore ideal for most typical size openings, although Sunflex doors go narrower and wider. If you’re wondering how big a door set can be when comparing Sunflex vs Origin sliders, the Origin product goes just under 12m wide. Sunflex doors can go up to 24 metres wide. That’s a very impressive sliding glass wall.

Similarities between Origin and Sunflex sliding doors

As you’d expect from two excellent sliding patio door brands, they also offer similar specifications. Here’s what you get with both of these doors.

  • High quality insulated aluminium profiles and a durable, low maintenance colour.
  • Excellent choice of colour shades from the RAL range or special finishes
  • Great thermal performance also thanks to our insulated glass units, safety glass of course.
  • The option of a standard or low track
  • Quality guarantees and a professional installation by alühome, premium partner for both brands

Either of these quality-made and expertly-installed sliders promises to give you a slim, reliable and above all attractive aluminium door in your home.

It is very important to remember that Origin sliding doors will only meet the latest U-Values as a triple glazed product. This information is confirmed by Origin themselves as the designer and manufacturer. You will not meet Building Regulations with Origin sliding doors as a double glazed product.

How much do Sunflex and Origin sliding doors cost?

Many factors affect the price you pay for these doors including sizes, number of panels, colour, glass type, overall specifications. It’s easy to get a fast price for these, so why not get in touch if you’d like an approximate or firm price.

We had previously looked at a number of companies for sliding doors and were disappointed by the lack of technical detail they could provide, so we were very impressed with the response we got from Aluhome. The discussions with Tim regarding details of the products and technical information was so helpful. We had sliding doors installed a few months ago. Very happy with the look and the operation of the doors.The Installation team were friendly, efficient and did an excellent job.We highly recommend Tim and his colleagues at Aluhome.

Tim, Aaron and the whole team at Aluhome created an incredible transformation to our home with their beautiful windows and doors throughout. An integral part of this renovation was to bring the garden “in” and Tim absolutely understood that we wanted clear, unobstructed views. He therefore recommended these superb patio doors which enhance not only the view but the feel of space and openness. We are absolutely thrilled with the result and cannot recommend Aluhome highly enough.

Tim and the aluhome team were incredibly knowledgeable and helpful and well worth considering if you're in the market for doors and windows. You'll struggle to find another supplier with this level of service, knowledge and attention to detail. Heartily recommended!

Thank you to Tim and your team for the great products you have supplied us to complete our extension. It was a pleasure dealing with your company. Tim’s product knowledge and advice was first class and a stress free experience. After our initial visit to the showroom in Stamford and discussion with Tim , it was an easy decision to place the order for our roof lantern and patio doors with Aluhome, and we were not disappointed !We would highly recommend Aluhome and would most definitely use them again .

Very satisfied from the first showroom meeting to final fitment of Bi-folds. No hard sell, just helpful and happy to spend time with you . Full fitment in 1 day with very good fitters. Pleasure to do business with. Would highly recommend

Always very professional, responded to our questions about specifications and options. The outcome is a great looking house with a great deal more natural light than we had with the windows that came with the house, I would estimate that it allows about 30% more light into the house than before.The installers were excellent and left the house clean and tidy after their effortless installation.The design of the window profiles is simple, clean and elegant with no frills just what we wanted.The triple glazing is much quieter than our previous double glazed windows.We are therefore extremely pleased with the outcome and have had many neighbours standing and staring at our new facade.

In October we started on a complete renovation of a grade 2 listed property near Banbury which would include a kitchen extension. The planning permission granted required the walls to be built almost entirely of glass. The local quote I received was bonkers and after much research found Aluhome. Their quote was more in line with what I had expected for exactly the same product. Working with Tim was a dream, their timing, delivery and installation was perfect and the product was exactly as discussed. There was a very small leak after some exceptionally heavy rains which they fixed with a smile as soon as the rains had stopped. All in all I couldn't be happier and highly recommend anyone give Aluhome a try. A big thanks to all the team.

We couldn't be more thrilled with the products and service we received from Aluhome. In particular, Tim Armitage, was so helpful and informative, and he was determined to give us the very best product for our budget. The time spent in his office thrashing out the finer detail was not wasted, and from start to finish we felt supported and guided at every stage. He even went above and beyond in offering advice on building companies, one of whom we ended up using, with stunning results. The installation team were fantastic - professional, always on time, and masterly in their work. The windows and doors were, to us, a vital part of our build, and even now, all these months later, we never tire of looking at them, knowing that we made the very best decision. The colour, thin profiles, and smooth workings are an absolute joy, they look so classy and beautiful. We put in extensive research online to get to Aluhome, and we will always thank our lucky stars that we did. Christine and Kev Yates

After many discussions about whether to go for bifold or sliding doors, we are delighted that we chose these Sunflex sliding doors. The 20mm sight line makes a huge difference when they are closed but opening them creates a wonderful inside/outside feeling. Tim is most certainly a guru when it comes to glass products and he clearly explained and demonstrated the quality of the sliding mechanism and the benefits of these doors. We thought we would need to have a double window over the sink but Tim informed us that if we made the window slightly smaller (150cm) he could provide us with a single pane window, giving a lovely uninterrupted picture view to the garden. He was very patient with our many questions and was keen to get it right for us. We had good communication from Anita who kept us well-informed of delivery and fitting dates. Aaron and his team of fitters did a great job and came back promptly to sort out one or two small issues. We are glad that we chose Alühome and highly recommend them.

We found Aluhome (don’t know how to do dots) on google, and what a find that was. If you want to work with a small independent business who take great pride in their product, service and reputation at a very fair price, you’ve come to the right place. Tim’s service is exceptional. He was ‘on it’ without being at all pushy – good sound advice and almost instant responses to queries, whatever time of day or night, as our spec changed. The skill of the survey and fitting was an absolute joy to watch. We couldn’t be more delighted with our Sunflex Bifold doors, with matching back door and kitchen window!

During our research we visited 5 window replacement companies and 3 factories producing frames. After a visit to Aluhome we quickly established a good rapport with Tim, the director, whose knowledge and experience exceeded all we had experienced. He established a clear understanding of all of our concerns and requirements, and reassured us they could meet them all.We are absolutely delighted with the windows and patio door. The quality of these aluminium frames, the powder coating and the ease of opening are all first class.We chose triple glazing at such little extra to the overall cost and it was well worth it.Aluhome have their own very competent and pleasant installation team. They are all very customer caring and reduced all the usual expected concerns we might have had.We are very happy to unreservedly recommend Aluhome.

Brilliant service all round. Tim had so much knowledge regarding the doors and ordering was very easy. Aaron did the survey, again very knowledgeable and helpful with keeping me up to date with home visit. On the day of fitting guys on time, quick fitting, extremely clean and tidy and all rubbish removed. My picture does not do the bi-fold doors justice. Would recommend to anyone and everyone

So glad we decided to switch from bi-folding doors from a different supplier to our amazing Sunflex SVG20 Triple track sliding doors through alühome! Worth every penny! Tim, Anita and the team were amazing from start to finish, even when we had a slight issue with the size of the large picture window, a solution was found. The actual delivery and fitting was completed on a tight deadline and they came back and sorted a small problem quickly and professionally. Tim was always at the end of a phone to give advice and that was much appreciated! If only other window and door suppliers were this reliable! We are so delighted with the finished result and everyone comments on how amazing the view is through the huge windows! We can’t wait for the summer to enjoy opening up the doors into the garden! Thanks again alühome!

Tim knows his stuff when it comes to glass!We had been keen to use a local supplier, as we wanted the assurance of speaking to a professional and seeing the product beforehand ,so we could make the right choices for our build .We were not disappointed ! Tim and his team were able to answer any queries we had and advise on on the best options for our needs.Installation was seamless.We are very happy with our new windows and sliding door.Mark and Kathryn

Amazing advice and service from the design phase through the installation phase and into after-sales. From the moment we engaged with Tim and the team we felt confident we were in professional hands. The ordering process and installation only confirmed our confidence. The whole team and the quality of the product was, and is exceptional. We will, without a doubt, commission Tim and Aluhome again for further requests.Basak

Really pleased with our new Sunflex sliding doors, we went with one end fixed 3 pane option in the end in Black. It really finishes off our extension and gives us lots of light from the garden. Tim was really helpful throughout and always gave us advice and honest feedback when talking through the options. The team of fitters were also great especially Aaron. Would highly recommend Aluhome and Sunflex sliding doors. Daniel and Nicola

Just want to say what a great after sales service Tim and his team supply.Had my lovely French doors fitted a couple of years ago and there was no hesitation in Tim sending out his team to sort out a small problem I had a couple of weeks ago. The guys are so lovely and friendly and really can’t do enough for you, checking over other aspects of the doors too…..(even sorted the latch on my side gate!). They are a credit to Tim and themselves. Highly recommend.

Can’t fault the service received from both Tim and the installation team. Have had the patio doors just over a year and absolutely love them. Wish we’d taken the time to research door suppliers at the beginning of our house build and used Alùhome rather than having an inferior product fitted by a different company. We have had a small issue since having the doors fitted last year and Tim has dealt with this swiftly and with no fuss. Highly recommend Alùhome.

To say we are chuffed with our new doors is an understatement! The level of service from the entire team has been fantastic. Tim’s sound advice ensured we got the right product and he kept in touch throughout the installation to make sure we were happy. The fitting team headed by Aaron were all friendly, courteous and efficient- taking time to ensure everything was spot on and tidy before leaving. The doors look great. They have opened up the view and an added bonus is that the UV glass keeps our south facing room significantly cooler during the summer. It’s rare to find such great personal service these days and we’d highly recommend Aluhome.

Aluhome (Tim, Anita and the team) have been fantastic. We chose Aluco crital style doors to give our home a bit of an update and we haven't been disappointed. Their are many glazing manufacturers and resellers on the market and we visited a fair few before deciding we felt most comfortbale with Aluhome. However, its really the aftercare that sets companies apart and Aluhome have gone above and beyond and we couldn't have asked for better customer care. We are so happy with our doors and should we ever move and need some new doors or windows, Tim and his team will be our first port of call without question. If you want to feel in safe hands and deal with a company that listens to what is a big investment to your home then we couldn't recommend Aluhome enough.

As a return customer I am very happy to recommend this company.Tim has proved most accommodating and helpful, and instillation crews have been diligent and tidy. We have a quality product that is worth the price paid, compared to standard companies we have used in the past.

Several years ago after moving house we started on what has been a long journey of renovating our chalet style bungalow both internally and externally.From the very beginning we knew we needed to transform the external appearance of our property and that our windows choice was critical in achieving the overall look we wanted. We had a vague idea of what might work well however in reality we were a million miles away from making a decision. Not only did we need to find a product which ticked all the boxes and could cater for a number of slightly larger existing window casements but also a supplier and installer who would carry out the installation on our stone and brick property to a high standard.After months of trawling around many different window companies and considering the finer details of numerous window profiles, we came upon alühome in Stamford.From the outset when we met the owner, Tim Armitage, it was clear that he was happy to spend whatever time was needed answering our questions and showing us the different window options. He was not only genuinely interested in our project but also clearly understood how important it was that we got our window choice right.After several visits to the showroom and discussions with Tim we became clear more and more confident that Tim and his team could deliver all that we hoped for and that our window investment would be in a safe pair of hands.As the months passed and our journey and relationship with Tim and Alühome continued, and well before we confirmed our order, Tim’s knowledge and experience became invaluable and it was with his support and guidance we made our decision to go with the Origin OW70 profile for our windows, a 4.8m Sunflex 3 panel sliding door, an Origin French door and an Origin back door.Almost 2 years after our first contact with Alühome our windows were installed in April 23. It has been a long journey but without any doubt Tim has consistently delivered in terms of his service and professionalism throughout. Understandably, and similar to all projects big and small, we have had bumps along the way we have needed to deal with, but each time Tim has done everything possible to accommodate and assist us.From the moment the first window went in we knew that we had made the right choice. The OW70 profile is slim, discrete and with the chamfered profile looks more like a traditional wooden frame window. The perfect style and look we wanted for our property and the colour RAL 7032 could not be better.I also can’t write this review without mentioning the installation team at Alühome. Aaron and his team were outstanding. Having different surfaces around our windows; stone, brick and lead, plus a number of different wall thicknesses, meant the setback of each window and how best to seal the edges needed to be considered. However, there was no need to worry, for each scenario there was a suitable option which Aaron was happy to show us and talk through. Aaron’s attention to detail is outstanding and this clearly shows in the quality and finish of our installation. A big thank you to Aaron and your team. You did a great job.Our project is not yet complete and our front door, also being supplied and fitted by Alühome, is still to be installed, so, at the moment we are yet to fully enjoy the benefits of our new windows and investment, however without any doubt we are truly delighted with our new windows. Along every step of our window journey Tim and his team have delivered beyond our expectation and shown us that they do care. We certainly made the right decision many months ago. A super big thank you

After struggling to find a supplier of aluminium sliding doors with integrated blinds that we wanted for our kitchen extension, I was very relieved to find Tim and Aluhome, who knew immediately that what we wanted was possible. From my initial email enquiry - that was answered within minutes - that led to a conversation, then showroom visit and ultimately purchase and installation, we were in very capable hands. Overall, we’re very happy with our doors and feature window and wouldn’t hesitate to use Aluhome again and to recommend to others.

Great support and service from Tim and the team throughout the process! After 2 difficult years with an East Midlands installation company trying to sort a sliding door, we approached Tim to ask for help in fitting a new sliding door to our bedroom. The team at Aluhomes took on the challenge and the professionalism they displaced throughout the project was exemplary. From site audit to installation, all discussions were really professional and supportive. The installation team, led by Aaron were great on the day. Thank you Aluhomes - a top job!

Having spent many weeks searching for companies that could supply the design of doors we required for our recent kitchen renovation, we found Aluhome.From our the initial meeting with Tim in Stamford, we had every confidence that Aluhome would supply, deliver and install their products within our budget and required timeline.After placing our order, the whole team worked closely with us to ensure their products met our bespoke requirements.Unfortunately, there were a couple of issues with some glass units during the installation but we are pleased to say these were actioned immediately with minimal impact to us.

Having settled on the design for a new extension to replace two old wooden conservatories we needed to extensively research the bi-fold doors, windows and lanterns as these accounted for a large part of our budget.We identified Aluhome as a company that supplied products from several different manufacturers which gave us the opportunity to see and compare the various products in one place. Once we met Tim it was clear that he had a vast amount of knowledge and experience in this area and we were confident that he would ensure we selected the right products for our project. Once this had been achieved, we agreed a delivery schedule and installation date. Delivery was on time and Tim’s installation team were very professional and conscientious at all times whilst on site. Suffice to say that we are extremely happy with the products supplied and the whole buying experience in general – Thank you.

From our initial consultation in the Aluhomes showroom in Stamford to the final sign off of the work this was a marvellous stress free experience in amongst the turmoil of our home extension. Tim has years of experience in the market and was very informative and helpful. Seeing full size examples of the various products was also very helpful.Communication was good throughout the process and people turned up at their appointed times both for the site survey and actual delivery and installation. All work was carried out at the time agreed by a very professional and courteous team who were thorough and made sure we were happy with the final result.Our installation included two sets of sliding doors and three floor to ceiling windows with which we are exceptionally pleased.

As previous reviews mention the Aluhome team come very highly recommended.We spent a number of months researching the best products and companies for our renovation project. We had a vision in mind and Tim and his team have helped us create that vision - we are extremely pleased.We met Tim at the Stamford showroom where we handed him the picture from a magazine - the vision! With Tim’s vast experience and knowledge in the glazing industry combined with his , enthusiasm, attention to detail and the quality of the products on show we felt confident to place our trust in Aluhome. Tim and his team have worked with us and kept us informed at every step on our journey. Tim worked with us to refine the design ensuring our budget could be met. The schedule for delivery and installation was constantly reviewed and updated inline with the builders schedule. The installation team, lead by Aaron, were a pleasure to have on site – they are friendly, professional with high quality craftsmanship and attention to detail. We had a particularly tricky entrance section - Tim and Aaron liaised with our builders and problem solved to come up with solutions.When undertaking a complex renovation project you don’t expect things to go right all the time - that’s real life. What makes Tim and his team stand out is that when obstacles arose they worked really hard to resolve them. The process was frictionless with Tim striving to provide a quality service and not settling until he was happy with the final product and ensuring we were also happy. This is a measure of a high calibre company and one you can have trust in.In summary : our experience is that Aluhome works as a respectful team placing their customers at the centre of the experience. They are a team that are extremely knowledgeable and experienced about the glazing industry and use only quality products. They are passionate about quality and have the skills to provide solutions to complex projects. They are also quite simply nice people with high standards and good values.
