In this article, we tell you all about why for slimline sliding doors, you get a better patio door with a Sunflex slider and where these doors have unique features, you won’t find on other sliding doors. .

With ultra-slim top and side rails that create a sleek, minimal look, these doors are engineered to provide smooth, effortless movement every time you use them.

First of all is their ingenious design. Highly thermally insulated profiles, combined with our high-specification glass units, creating doors with excellent energy efficiency, and saving you money on your energy bill.

Then is the advanced rolling system features innovative ball bearings and self-lubricating wheels. Moving the doors is effortless and near-silient, regardless of how large your sliding doors may be. A slimming design, yet designed to be heavy duty, operating beautifully every time.

Whether you’re looking for a minimalist glass wall to define your new space a large, unobstructed view of your garden or patio area, SUNFLEX slimline sliding doors are a perfect choice.

Slimline sliding doors with the best styling

When choosing slimline sliding doors, you benefit from smaller aluminium sightlines. A reduced aluminium sightline also provides you with more glass, more natural daylight and improved views out to your patio area, the Lincolnshire countryside and giving your property renovation project a feeling of more space.

The Sunflex SVG 20 is a genuine slim-frame system – slender lines, flexible designs and above all the finest styling and design. Of course, the desirable 20mm mullion is its standout feature.

Unlike other sliding doors on the market offering the same 20mm mullion sightline, Sunflex slimline sliding doors are designed to be better. Look at any other sliding door system, and you’ll see, that whilst the 20mm mullion looks slim face-on, it’s actually quite bulky from the inside. And with some systems, this thick mullion can project more than 150mm, and past the door frame.

Sunflex SVG20 sliding doors have the desirable 20mm sightline, with none of the projection. The doors look flush with their frame and track from whichever angle you view them. There’s no other sliding door on the market that looks as good as a Sunflex when it comes to that all-important 20mm mullion sightline.

Compared to other sliding doors on the market, our sliding door system offers unrivaled performance and versatility. Unlike other doors that require heavy and cumbersome frames for their tracks, our narrow combination of frames makes installation quick and easy.

Additionally, unlike other systems that rely on bonding or reinforcing to give you a 20mm sightline, our slimline sliding doors are bonded only at the mullion and not the entire door set.

A unique flush stacking design.

Another unique feature of Sunflex sliding doors is their ingenious flush stacking design. All other sliding doors, fully open result in staggered door panels. The result is this staggered opening takes up more of your available opening.

Sunflex slimline sliding doors stack completely flush on a two or three panel design. They slide right back, neatly together. You benefit from more of your available opening. Even better, these doors look neat and elegant fully open – something not available on other sliding doors.

The smoothest sliding action

The engineering and design behind every Sunflex sliding door also extends to what you can’t see. Hidden outstanding design, giving you one of the best experiences.

What you don’t see with a Sunflex sliding door is the stainless steel quad rollers operating on a stainless steel track. Where other sliding doors have just have a roller set on each end of the panels, Sunflex sliding doors have more.

The result is a sliding door that feels spectacular to slide open and closed, with one of the best transitional movements, no matter how large or heavy.

Helpful advice given and three alternative plans fully drawn up and priced for us to choose the best option for us.

The planned timetable was stuck to and the guys got on with working even though it was raining.

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.

Thanks to Tim and the team!

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.
