What to look for when buying bifold doors

When it comes to buying bifold doors, most of the folding sliding door products on the market promise the essentials – security, good weather performance and fully opening up on warmer days to your patio or garden. In this guide to buying bifold doors, we explain some of the essentials but also help you with other aspects around folding sliding doors, helping you make a better buying decision, and getting a more superior product for your new extension or property renovation project.

advice buying bifold doors for a new extension

The advantages of higher quality bifolding doors explained

Any bifolding door provides a visually appealing patio door in your new extension or as a replacement for your dated patio doors. You’ll get a brighter room with excellent views out to your garden.

Open up your doors in the spring or summer and you’ll enjoy a seamless link from inside to out – an extension of your kitchen or living area. Even better with a bifold is their flexible configuration with your panels sliding in one or two directions.

A well-designed bifold can also come with a lower or flush threshold connecting your inner floors to your outside decking or slabs, but with full weather and water protection.

Configure your new bifolding doors correctly and you can also enjoy similar functionality to regular doors making quick garden access or ventilation easy, without having to fold the panels back every time.

The only disadvantage to bifolding doors is understanding the sheer choice when all materials and many brands seem to offer the same benefits. So let’s start giving you the tools you need to buy better doors without breaking the bank.

Why aluminium is best when buying bifold doors

Aluminium is by far the best material when buying bifolding doors. You’ll get similar security, weather protection and function with aluminium, PVCu or timber. However, compared with PVCu and timber doors, aluminium is always slimmer and provides larger glass sizes. The larger glass sizes matter a lot in your choice of bifolding door.

The larger glass sizes from slimmer bifolding doors give you more light, better views and a more pleasing outlook, especially when the doors are closed. And remember, our bifolding doors are closed most of the year.

Another reason why aluminium is best when buying bifolding doors is larger bifold panel sizes. Most PVCu doors typically go up to around 900mm per panel. Aluminium bifolds go up to 1200mm wide with most brands and even up to 1500mm wide with a Schuco-branded folding sliding door. The same applies to bifolding door heights with aluminium exceeding other materials in how high your doors go up to.

Why does this matter? Aluminium bifolding doors give you fewer panels than other materials across the same size opening. Fewer panels again mean larger glass sizes, fewer visible mullions and altogether better bifolding doors in situ.

Colour is yet another reason why aluminium is better when buying bifold doors. There’s no other material offering not just a choice of shades but also different textures. Aluminium bifolds give you over 200 different colours. Better than PVCu or timber bifolds are colours with texture. Or you can choose an authentic woodgrain finish if your property needs it without the maintenance of wood doors. When you want ultra-modern, metallic colours deliver an altogether different look and feel to your new folding sliding doors.

Why sightlines matter on bifolding doors

The less visual bulk in your doors, the better they look. So look for bifolding doors with slimmer sightlines when all the panels are closed. Many bifolding doors on the market offer mullion sightlines of around 135mm to 154mm or more. The good news is there are slimmer models on the market.

What’s the benefit of slimmer bifolds? Apart from more pleasing lines, it’s another reason for getting larger glass panels and a more spacious feel in your room.

The Origin slimline bifold has sightlines of only 110mm, making it one of the thinnest premium quality bifolds on the market. Even better with this door is getting matching single or double doors with the same neat proportions. Our Solarlux product is the slimmest, with 99mm mullions and you’ll be hard pushed to find a thinner product on the market. Or for something in the middle, Schuco has the most popular and desirable aesthetic at 120mm.

So our advice for getting the best looking bifolding door is to look for those with thinner sightlines.

How better hardware matters when buying bifold doors

One of the best ways of understanding what makes a better bifolding door over and above what you get with any bifold is the quality of the hardware.

The lighter, quieter, smoother and effortless a bifold is to fully fold is your best clue to the quality of the hardware and the product. For the best operation, nothing beats the German-designed or made bifolding doors like Solarlux or Schuco. Don’t just take our word for it. We’ve got three brands in our showroom and you can come and see this for yourself.

Then it’s the quality of the hardware itself. Most lower-priced bifolding doors come with the same style of handle you get on cheaper doors where you see one handle combined with the key cylinder.

A higher-end bifold comes with more luxurious handles that simply look and feel better at first glance. Another feature of a quality bifold is those with a separate handle to the cylinder. Not only does it look better but the handles are significantly more premium with marine-grade metals that are thicker. Locking and opening the doors feels simply better. Of course, these types of handles last longer and are less prone to the dropping and sagging you get with cheaper handles.

The quality of the hardware also extends to critical components like the door seals. Origin bifolds are unique in giving you gaskets colour matched to seven different colour combinations. There’s nothing better than a white bifold with white gaskets or a grey modern finish with the seals in a similar colour. It’s another quality indicator when buying bifold doors.

One of the characteristics of any bifold is how much of the hardware is visible. So what better way to make these visible door rollers and guides look better than choosing what colour they come in? It’s another great quality clue when buying bifold doors and our range gives you these options.

Why low thresholds are not all the same when buying bifold doors

Want the low and flush threshold on your folding doors? Here’s another area where the upper-tier bifold surpasses a standard door on the market. Most regular bifolds only give you two threshold options – the standard and a low version. The problem with the low version on many brands is it’s only intended for internal use. So many brands work on setting the standard threshold lower giving you the flush look. And in most cases, this is just fine. We also offer this option.

Better bifolding doors give you more than two options and some of our doors come with up to five different threshold solutions. If you want a low threshold for its styling any bifold will meet your needs. If you need a low threshold for better accessibility and weather performance, perhaps you have a relative with a wheelchair or mobility issues. Better bifolding doors give you more options at the threshold and again, our product range meets most requirements. It’s another consideration when buying bifold doors.

Understanding what are the best bifolding doors sizes

The size of your existing or new door opening determines most bifolding doors sizes and indeed whether your opening suits bifolds or whether French doors may be more suitable in a smaller doorway.

Generally, openings of more than 2.2m wide are suitable for a three panel bifold right up to larger folding glass walls with multiple door panels spanning up to 8 or more metres.

Another consideration is the number of panels. Going for wider door panels could also mean fewer of them. We have bifolds providing solutions with three panel designs where many other brands need four panels across the same size of opening. Contact us and we can help you design the best bifolding door at the most suitable sizes for your use and your property type.

Overall, when buying bifold doors, consider larger panels combined with slimmer bifolding door profiles that give the best look overall, for maximum light, reduced aluminium lines and better bifolding doors.

From start to finish aluhome have been brilliant. Great communication and informative advice in the initial enquiry,... with excellent product knowledge from the sales team enabled us to choose exactly what we were looking for. Even with inevitable delays with manufacturing we were kept up to date all the time from the friendly team. Attention to detail on survey ensured that our builder knew that he needed an extra level of brick to achieve the seamless flush finish on our sliding doors and the installation team have done a great job. We wouldn’t hesitate in using Tim and his team again and would definitely recommend them. We are more than pleased with the finished look. Thanks aluhome.read more

If you are looking to buy new windows/ doors which I guess you are as you are looking at this review, aluhome is the... place to go. From my first phone call & subsequent e mails with Tim we felt that we were dealing with a very friendly & efficient company. This was indeed the case when we visited the showroom & were greeted with a lovely coffee. We didn’t any feel any pressure to buy but as we loved the product we did order there & then. The fitting team arrived promptly on the arranged day & were very friendly, polite & efficient & what’s more after they left my sitting room was beautifully clean, I thought that maybe I should offer them a cleaning job😀. After a few days we did have a slight problem with the door lock but after a quick word with Tim he sent a couple of guys out the following morning to fix it, you can’t get better service than that. Thanks to you all, we love our new sliding doors.Inboxread more

Tim and the team at aluhome were an absolute pleasure to do business with and our 6.5m sliding doors look amazing. The... level of detail that Tim goes into inspires confidence and proves that you are dealing with a professional. Our Sunflex doors were a significant component in our build and essential to making the whole project a success. Our close friends relied on our recommendation and are also trusting aluhome to provide the wow-factor to their home renovation project. Even after fitting the doors aluhome could still be relied upon to deal with a small, but significant, issue with the glazed units. This shows that aluhome care about their customers' happiness and is why I will continue to recommend them to friends and family.read more

We spent a number of months researching the best products and companies for our complex renovation project. As soon as... we met Tim at the Stamford showroom we were convinced the aluhome team would deliver the product set and installation service we needed for our project. Tim worked closely with us to refine the products we wanted, to ensure our budget could be met and to create a delivery and installation schedule. When it came to installation the team, led by Aaron, were highly professional with an excellent attention to detail. In summary, Tim and his team are passionate and extremely knowledgeable about this industry. They provide truly bespoke solutions, collaborate very effectively with their clients and deliver quality every step of the way.read more

After an awful experience with a previous installer, Tim and the Aluhome team were like a breath of fresh air,... delivered exactly what they promised, doors were a little delayed due to the pandemic, but Tim kept us informed every step of the way, I have no hesitation recommending, the service and quality workmanship was truly outstanding and that’s more than I can say for most of the other companies in this space, who seem intent on giving the industry a bad name, thanks again Tim, our front and back doors look and perform just as you said.read more

A high quality service from start to finish. The show room is excellent and reassuring as this element is lacking with... many companies. Tim's knowledge and advice was brilliant throughout. The customer service and communication provided by the whole team was great. Before confirming my order I was told an installation date 6 weeks later. The bifold door and window were installed exactly when I was told. I know from experience that this rarely happens and this reliability made the build much easier. Tim's surveyor and fitters were all excellent. They were very professional and did a great job. I had a problem with a scratched pane and this was replaced quickly and without question which I was very pleased with. The door and window both look stunning. Exactly the look we wanted and they feel very high quality. We are very happy we went with Aluhome. Thank you guys!read more

What a fantastic company! I had been searching for a specific configuration of interior and exterior doors and windows... and was struggling to find them. Then, by accident I came across Tim's company. From the moment we started to communicated I knew who I wanted to work with. Tim's techncial advice from choosing the right solutions, through to how to manage the site build requirements was second to none. The professionalism of his surveying and installers teams, didn't let me down in any department. Always professional, courteous, and tidy, while at the same time a pleasure to work with.read more

Exceptional company to purchase from, small enough to care but large enough to supply the sliding doors in a... configuration we couldn't find anywhere else. Frame rebate was one of the smallest we could find with 3 extremely large doors that did not need to be fixed in any specific position when open. We can know look out on our back garden and barely notice the doors. Tim and Anita are both Amazing and so are the guys that fit the Doors. Very happy to recommend!!read more

Thanks to ‘Aluhome’ for first class (well Informed) advice with regard to the suitability of replacing our existing ... French doors with a Less obtrusive Aluminium framed Sliding Door system.What a difference! - the views into our garden now they are clear of window frame obstructions is delightful. This coupled with more natural light to the interior, is another bonus.The installation was carried out by fitters who clearly knew their trade and with the minimum of inconvenience to us.We are happy to report that the finished job from appearance, practicality and quality, exceeded our expectations.read more

Tim and his amazing team have been a godsend during our extension project. His advice and friendly chats together with... his highly experienced team of surveyors and fitters made the whole experience simple and hassle free. What he doesn’t know about his products isn’t worth knowing and we came away from the showroom feeling knowledgeable and that we’d made a great informed product choice. A big thank you to the whole team, and I promise once the garden's done and the kitchen's in we will update our photos which currently I’m almost embarrassed to upload as they don’t do the bifolds justice at all! We love them, the light is amazing, thanks again Tim & Team!read more

Based on our recent experiences, we are happy to recommend aluhome. During a visit to their office and display room Tim... was able to give a comprehensive description and assessment of all aspects of the door and windows we were thinking of installing (replacing 25 year old wood framed patio doors and windows). The timing of delivery and installation was as predicted. The cost was more competitive than similar offers. The installation team were on time, friendly, competent and efficient. And they left the patio area as clean as it was beforehand. And we are now very pleased with our new patio door&window. Best wishes, Rick and Moread more
