The enhancements by SUNFLEX to this product allows multiple configurations such as a single panel sliding up to a sliding wall with multiple panels up to 24 metres wide.  Sliding patio doors form part of the range of patio door solutions from SUNFLEX, which includes Bifolding doors.

SVG20 sliding doors.

sunflex sliding patio doors svg20 slimline model.

The thinnest and most contemporary in the SUNFLEX UK range is the SVG20 model. The standout feature of this door is its 20mm sightline without the complexity or projecting mullion of other structurally bonded systems. Even better is the angle of view giving consistent slim looks.

Available in many configurations, including pocket sliding and open corner designs, the sightlines and overall proportions make this product not only attractive but infinitely flexible.

SVG30 sliding doors.

sunflex sliding patio door

Ultra-slim sliding patio doors featuring a mullion sight line of just 30mm.  The stand-out feature of SUNFLEX SVG30 sliding doors is providing the same thin profile sliding door mullion found in high end, structurally glazed doors. Furthermore, this door does not rely on the typical deep mullion feature found in these doors either.

As a result, you get a much cheaper door with all the aesthetics of high-end doors. With the SUNFLEX SVG30 product, there are also none of the associated costs of transportation and installation typical of structurally glazed doors. As well as the benefit of slim sight lines and lower cost, SVG30 sliding doors offer the option of multiple tracks and panels, huge colour choice and high security. There is also the option for a lift and slide method of operation.

SVG83 sliding patio doors.

open corner sliding doors

SUNFLEX SVG83 sliding doors offer all the benefits of the SVG30 with an 83mm mullion. This particular door offers the reliability and strength needed for doors panel over five square metres.  One of the best features is the open corner design with a movable corner post and doors disappearing into a wall.

This larger span door provides heights up to 3.2 metres high and also reduced heights, creating contemporary sliding windows. It also offers the option of a fully recessed door threshold with the sought-after weather protection many other doors cannot provide. Best of all it creates a highly desirable and neat finishing detail where the sliding panel meets the internal floor.

Frameless SF20 sliding doors.

I contacted Nick @ ATS for guidance on what aluminium sliding door systems would be suitable for an opening in an extension that is going to be both wide and tall. He came back really quickly with very detailed and incredibly helpful advice. He is clearly extremely knowledgeable about the systems on the market and their respective features and capabilities. If you’re feeling a bit lost by the overwhelming range of choices out there, I’d definitely recommend contacting him.

After a lot of research to find doors that would meet our unusual size requirements and feeling increasingly uncertain about the best way to spend our small budget, I stumbled on the ATS website, and I'm so glad I did! I contacted ATS to request advice and Nick promptly replied with a wealth of information, providing us with options and relevant contact details. I only wish I'd found them sooner!

I've been so confused about how to achieve the look I'm after, and going round in circles with various window/door companies, trying to get away from the huge chunks of plastic currently around my windows. I didn't expect an email to a company found through a Google search to really help - but I was desperate, so I tried. I'm SO glad I did. Finally I have clear explanations from ATS of where I've been going wrong, exactly what I'm looking for, and a list of local companies that might be able to provide it! The response has excelled my expectations and I feel as if I'm finally inching closer to a home with which I'll be happy and comfortable: thank you.

It is rare that I write reviews, however after my very positive communication with Nick - enquiring about suitable slim sash aluminium windows for my project, I felt that a review was definitely warranted. I can reinforce the many positive reviews posted so far, Nick was very quick to respond, providing comprehensive detail, with excellent independent advice.In summary, great service, thank you Nick.

I dropped Nick at Aluminium Trade Supply an email re high security slim sightline bi-folds and their alternatives and he responded that quickly (and so comprehensively) that I felt bad I’d not paid him for his time!Nick Sir your product knowledge is outstanding and you are providing a level of service that goes wayyyy above and beyond expectations. I’ll definitely make sure I mention Aluminium Trade Supply to anyone I encounter looking for a fenestration solution 🙏🏼

We are looking to replace some old UPVC patios doors with aluminium ones. The ATS website is a great source of advice in an area where clear information is sorely lacking. Having used the website, I then followed this up with a number of specific questions relating to our search, and Nick came back very quickly with clear, detailed and very useful advice.I have been very impressed with both the website and with Nick's advice. My only regret is that I didn't come across ATS before replacing various windows in 2021 - I'm sure it would have saved me a lot of grief and money! Thanks again Nick.

My experience with this firm was exceptionally good and this is notalways the case as a female, dipping a toe into technical waters.I was spoken too with courtesy and at a level that helped me consolidate what was needed .On top of that I was given a list of companies and places where I could obtain the type of product I needed.I could not thank them enough and would certainly go there again and reccommend others do too.
