Comparing the aïr aluminium sliding door with Dutemann

The aluminium sliding door remains popular despite the desirability of the bifolding door. For homeowners looking for a large glazed wall without the visible mullions of a folding door set, sliding doors are a highly attractive proposition.  So we are going to compare the aïr aluminium sliding door with the  Dutemann equivalent.

Air vs Dutemann. The companies behind the brands.

There are a lot of sliding doors to choose from, and several aluminium fabricators have brought out their own sliding door brand. Two well-known products in the premium sliding door sector from independent manufacturers and trade suppliers are the Dutemann Glide-S from Kent-based Dutemann and the Air 500LS fabricated by Everglade Windows of Middlesex.

Both Everglade Windows behind aïr and Dutemann are prestige fabricators of aluminium systems.

Dutemann is an excellent trade fabricator making the outstanding Glide-S sliding door and also the FD85 bifolding door. You’ll also get a variety of Schuco products from the company too.

Everglade Windows are not only behind the aïr suite of bifolding and sliding doors but also one of the UK’s best known and established aluminium and PVCu trade suppliers. Everglade has a substantial operation in Middlesex with a massive investment in the biggest and best machining centres, a very impressive home improvement showroom as well as a separate showroom showcasing only air folding and sliding doors.

The high end market demands better, larger and more impressive aluminium doors. Aïr and Dutemann doors are two such products.

Everglade Windows has a strong presence in the commercial sector for housing and large scale contracts, the direct residential market and a well-established trade supply service to the home improvement industry.

Dutemann is very focused on their three key product groups of Bifolding Doors and Residential Front Doors based on Schuco. Sliding doors are based upon the Greek Alumil System. Dutemann is a smaller but nonetheless very competent aluminium business that is expanding.  Credit also has to go to Dutemann for the Dutemann Haus entrance door. A very good aluminium front door that we think has contributed to the recent growth and new systems serving the premium aluminium front door market.

How are aïr and Dutemann products supplied?

everglade windows factory
Everglade Windows are a multi-award winning manufacturer and exclusively provide air doors.

An aïr door is provided through a network of accredited air dealers.  These are established window companies some of which have been trading for over 30 years. Dutemann operates in a similar way with many specialist door and window installers offering the Glide-S, Dutemann Haus Residential and Bifolding Door.

Everglade operates what they call ‘aïrzones’; dedicated sliding door areas in a showroom dedicated to the aïr brand. Branding, literature and product placement are all consistent and strong.

The resellers of Dutemann sliding doors we know have sets of doors installed in their impressive showrooms but without the evident branding that air doors possess.

Both products are supplied directly by the fabricating companies exclusively; nobody else manufactures Dutemann or aïr doors. For an installer considering either of these two products, the marketing support and service offered by air does help sell the doors. This is not to say Dutemann doesn’t do a good job of helping their installers, far from it.

The advantage with Everglade for a potentially interested installer is that they also have access to the wider Everglade product range including PVCu windows, composite doors, Smarts aluminium and Reynaers products. Everglade also holds customer training days and seminars, provides the Valentis Installer Scheme, has retail facing websites, the point of sale materials and other benefits to installers.

The sliding door products available from Everglades’ aïr brand is the aïr 500LS inline sliding door and the aïr 600 LS lift and slide door.

Dutemann offers lift and slide as well as inline sliding doors under the Glide-S branding

Both aïr and Dutemann sliding doors provide latest generation sliding doors providing:

  • Inline or lift and slide contemporary sliding doors.
  • A cornerless solution.
  • Sliding doors that slide into a wall giving a full clear opening.

Both air and Dutemann sliding doors are premium products aimed at the quality-conscious and discerning homeowner. In our next article, we take a closer look at the technical specifications of the aïr and Dutemann sliding door offering.

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.
