Information about buying Sunflex sliding patio doors

The Sunflex brand is one of the best-known amongst premium glazing systems, windows and doors in the UK. The sliding model is made in the UK. There are also ultra-premium Sunflex bifolding doors, made in Germany and has some of the best aesthetics, quality and design on the market today. In fact, Sunflex and our own Solarlux brand are often compared to side-by-side. They’re probably the best on the market today.

Only Sunflex makes their doors. As a result, the company is in an upper-tier level of manufacturers only making their products. This differs substantially from brands such as Reynaers, Smart Systems, Cortizo, Aluk or Schuco. With these brands, many different and unrelated businesses make them. Whilst you won’t get a bad product with a good manufacturer, what you can’t guarantee is consistent product quality. Therefore, when only the company behind the product makes it, it’s generally a very good sign of consistent quality and a very reliable door in your home.

When buying Sunflex sliding doors you deal with an authorised distributor of their products. We’re proud at Aluhome to be a supplier of these luxurious and expertly-crafted patio doors.

Some great features of Sunflex doors in your home

With slimline sliding doors being one of the most popular requirements with homeowners and property improvement projects, the sightline at the door mullion is heavily marketed as well as desirable. There are many brands on the market providing the sought-after 20mm mullion sightline. Specifically, this is the central mullion you see on a two-panel set of doors or the two vertical mullions on a three-panel design.

Bear in mind that many of the patio doors offering this 20mm mullion come with a structurally bonded design. Structural bonding means a more complex product to make, transport and install. Sunflex provide a solution without the complexity and with substantially better sightlines.

And for where the slimmest door isn’t essential, Sunflex doors also come with a 30mm mullion and a more bold 83mm version.

Door panels up to 3 metres high and capable of creating spans up to an incredible 24metres. You might not need these extreme sizes in your home. However, what this demonstrates is the design, capability and exacting standards of Sunflex sliders.

Of course, you need your doors to slide effortlessly. These doors simply glide, whatever their size. You also get certified security, excellent weather performance and the same neat sightlines whatever angle you view them from. Finally, moving the doors means engaging with the door handles. Sunflex doors come with recessed, rectangular, bar and standard handles. All of these are architectural quality and look stunning on the door set.

A better and slimmer door mullion

With most structurally bonded designs, the trade-off is the depth of the mullion. So whilst it’s 20mm on the face, the depth is more than 100mm with most systems. The Sunflex SVG20 model provides the same desirable 20mm face sightline, with the same depth as the rest of the door. Click on the images to enlarge and see the detail.

Buying Sunflex sliding doors means neater stacking panels

Sunflex designs their doors stacking neater than many other similar designs. Therefore, the doors simply look better when fully opened, also making more of your door opening.

The image below shows a pocket sliding door but the same flush stacking applies when buying Sunflex sliding doors in a standard configuration. And when the third panel slides fully open, that’s flush too.

In addition to the flush stacking panels, the threshold on Sunflex doors is a work of art and substantially better engineered than many doors on the market. It also comes in a fully flush design with no loss of weather performance. Our Aquabocci rainwater system also works a treat with these doors.

Pocket or open corner sliding doors

Nothing creates a wow factor in a new extension like an open corner design. And for where you want to maximise the door opening, pocket sliding doors slide into the wall out of sight.

These types of designs suite newly built openings but with these doors, you get all the desirable looks, style and functionality and without the substantial cost or complexity of other door brands. It’s great solution.

We have been delighted with the Aluhome Service. The initial design and specification was thorough and despite a delay in manufacture the installation team were flexible and very helpful. The windows look fantastic and we would thoroughly recommend Tim and the Aluhome team.

Very friendly staff/workers, the process went smoothly from start to finish and the windows and doors are extremely high quality.

We're very pleased with the results.

We recently had slimline aluminium patio sliding doors installed by Aluhome and we’re really pleased with the result. The doors look fantastic and have completely transformed the space, bringing in much more light and giving a clean, modern finish.

From the initial enquiry with Tim through to installation by Aaron and team the whole process was smooth and professional. The team were extremely helpful, knowledgeable and great to deal with throughout.

A small prei-installation issue did arise, through no fault of anyone’s but it was handled straight away and professionally, which really showed Tim and Aaron’s commitment to customer service and ensuring a first class service is provided

Overall, a great experience and we would highly recommend Aluhome to anyone considering doors or windows.

Aluhome was a fantastic find for us. Tim is incredibly knowledgeable and helped us navigate the onerous energy efficiency and overheating requirements placed on us by building regulations. He has an eye for the detail as well as the design. He created a brilliant bespoke back door exactly to our requirements.
Aaron and the fitting team did a great job both at initial installation and the later follow ups.
The Origin windows are a brilliant product robust with a great look and the Cortizo slider is amazing. Thanks Tim, Anita, Aaron and the team.

I randomly came across Aluhomes while researching Aluminium sliding doors online, and i’m so glad I found them. Tim the owner is really nice and knowledgable and made so much effort to get my order through in time even though I left it to the very last minute. Before they took on my order, him and his team made sure they could logistically get the glass through my front door as I didn’t have any side access, which most other suppliers didn’t even talk about to ensure I didn’t have any extra costs for installation.

We purchased the SunFlex20 sliding doors, which are absolutely beautiful.

I am based in Greater London so was really happy they were willing to travel to me and compared to other suppliers they were well priced and the service was second to none. Tim gave me all the information I needed to make an informed decision and I felt like I was in safe hands which was reassuring especially when purchasing a large order like this.

If I ever want to purchase Aluminium doors in the future without a doubt Aluhomes will be my first choice. Thanks again Tim & Aluhome team!

Many thanks to Tim, Aaron and the team at Aluhome. Our product and service has been first class. We were quite specific about what we wanted, which wasn’t a big grand project, but the quality and attention to detail was still great. Having worked in the glazing industry I was wary about who I could trust with my own home, but I’d definitely recommend Aluhome!

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.

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.
