Introduction to Bifold Doors

If you are considering installing a bifold door in your home, this article offers all you need to know about bifold doors, including what they are, how they work, the types of bifold doors, the best bifold doors on the market, the cost to install a bifold door, and what to consider when purchasing one.

What is a Bifold Door?

Bifold doors, unlike regular doors, slide open with panels that fold up against the wall.

Additionally, they are quite popular as they are known not only to look beautiful but are also a great way to make smart use of your home space.

Additionally, since many bifold doors feature glass panels that let in light, they are a clever way to improve the lighting of your home.

In fact, these aesthetic doors have a fascinating history as excavations have shown that they were quite popular in Pompeii, where famed historian Peter Connelly claimed they were used extensively.

According to him, ancient Romans didn’t like single leaf doors and, therefore, opted for those with more elegance, which is where the bifold door came into play.

No doubt, it is easy to see the Romans using such a system as they are a civilization well known for their stunning architecture and love for extravagance.

That said, in more modern times, Bifold doors have become popular with those who want to increase the aesthetic appeal of their homes, and their smooth operation makes them a very reliable system to have in the house.

In fact, bifold doors are quite versatile and can be used both within and outside the house and commonly be seen in homes with garages, summer houses, and other such spots.

What’s more, when indoors, Bifold doors are used in a variety of ways, including entrances to laundry rooms, closets, and so on.

How Does a Bifold Door Work?

Bifold doors rely on a tracking system that runs smoothly and connects the panels. The door folds up against itself and opens easily to reveal the space behind it.

Also, the doors tend to come with wheels that aid the smooth transition from closed to open. As for the components that the doors rely on, they generally come together in a set and are installed in one go.

Furthermore, even though the doors are called bifold (meaning two-fold), they can have anything from two to seven panels, all of which are stitched together with hinges and connected to a roller track at the top or bottom, or even in some cases, both.

On top of this, the doors can come in two sets with two panels each that fold up against each other on either side. This is typical for a small bifold door that’s located inside a house.

However, for the outdoors, you are more likely to find one single door with several panels that slide to one side. So, they are quite easy to operate and durable.

However, it should be noted that bifold doors located outside need to be well fortified to stand up against the elements.

Types of Bifold Door

If there’s one thing bifold doors are not, it’s one-dimensional. Therefore, they come in different shapes and sizes and are made with different materials, each with its advantages and drawbacks.

We’ll look at the various types to provide further context and shine a light on them.

Aluminium Bifold Doors

Aluminium bifold doors have grown in popularity in recent times, with many people touting it as the best type of bifold door on the market. Are these claims true? That depends on your preference; what is factual, though, is that they have a lot of advantages.

For instance, the material they are made from aluminium is very durable and doesn’t corrode or rust easily. Also, since aluminium is a low-density metal, it tends to be light, which means you’ll have no problem operating the doors.

On top of that, they come in a variety of sizes, which means they can be used in any type of home.


  • Lightweight yet strong and durable.
  • Easy to operate.
  • Aesthetically pleasing and available in various colours.


  • They don’t do too well in wet areas since they can’t stop the constant flow of water.
  • They could be quite costly to install.

Timber Bifold Doors

This is a bifold door that makes use of timber as the prevailing material in its construction.

It is cheaper than aluminium and isn’t as prone to water leakage. Also, of note is how aesthetically pleasing it is. This is due to the natural colour of wood, which pairs pretty well with glass and is a beauty to behold.

That said, it has all the normal advantages that bifold doors come with, including ease of use and lighting advantages. However, on the flip side, while it isn’t as prone to leakage, it absorbs water a lot, which could cause the wood to rot.


  • Aesthetically pleasing and lovely to have around the house.
  • Isn’t prone to water leakage
  • More affordable than most


  • It absorbs water, so the wood could rot.
  • It requires a lot more maintenance than the other types.

uPVC Bifold Doors

uPVC bifold doors are the most commonly used for outside doors. uPVC, or unplasticised polyvinyl chloride, is a hard plastic that isn’t particularly flexible, but it is also really cheap and easy to work with.

Therefore, they have become quite popular with bifold doors as they are sturdier than timber and more affordable.

In addition, these doors deal with sound well and don’t require much maintenance, which is one of the reasons they are so trendy with many homeowners.

Furthermore, their neutral colours help them blend with most environments.

Unfortunately, there’s not much you can do with them aesthetically as they don’t absorb liquid well, which means you probably shouldn’t try to paint on them.


  • Affordable and easy to work with.
  • Blends in with most environments.
  • Sturdy and lightweight.


  • It can’t be painted over.
  • uPVC gets bent out shape in a fire and can burn easily.

Cost to Install a Bifold Door

Now that you’ve decided on the door you’d like to buy; the next worry is how you’ll go about the installation process and how much it will cost.

Installing a bifold door is a very specialized process and will most likely require a professional.

It isn’t impossible to go down the DIY route, but it isn’t advisable as if something goes wrong, fixing it would set you back even more money.

That said, while getting the door is pretty expensive, you can get your hands on the average tradesman for between £150- £200 a day. Apart from that, you might need to consider whether your specialist will need to subcontract parts of the job.

Also, the tradesman might need some help with the heavy lifting, and they usually work in pairs.

Additionally, some situations might require a structural engineer’s services, which could set you back a further £100.

What to Consider When Purchasing a Bifold Door?

Buying a bifold door isn’t so difficult, however, to get a good product that you are happy and content with there are a few factors to consider.

We will examine a few of them below to aid you when making a choice.


There are different types of bifold doors made with different materials, with the most common ones being aluminium, timber, and uPVC. Each of these materials is great to use and has its advantages and drawbacks.

For instance, aluminium is light and strong, meaning it can last for decades. However, it is also susceptible to water damage.

Meanwhile, timber is beautiful to look at and makes the aesthetically pleasing doors, but it also absorbs water a lot, which could lead to rot.

uPVC, for its part, is pretty affordable, which makes it one of the most common bifold doors bought, yet, it doesn’t possess the durability or stability of a material like aluminium.

So, while your uPVC might last for aReview couple of years, it might not go the distance.


The importance of security for your home cannot be overstated, and if you don’t feel safe, it can lead to anxiety and a poorer quality of life.

Therefore, before purchasing a bifold door, it is necessary to ensure that it has excellent security features.

The measuring tool for door security is the PAS 24 rating system, which informs you of the level of security you can expect from your door.

Protective of Health

Also, of note is the cylinder system and the hinges, the best bifold doors have robust hinges that aren’t easily displaced.

Also, if you get a new door, ensure that the cylinder is durable enough to withstand some of the more common burglary techniques, including bumping, drilling, and so on.

Thermal efficiency

Of what use is a beautiful door that lets in vast amounts of light and beauty but can’t protect you from the harshest weather conditions.

For this reason, the thermal efficiency of any door you seek to buy is of utmost importance.

For instance, aluminium bifold doors are well known for their thermal inefficiency. This is because aluminium is a good conductor, but with modern technology, aluminium isn’t the liability it once was.

Nowadays, you can purchase an excellent bifold door with proper insulation and warmth. The U-value is the measure by which energy efficiency is judged, and ideally, any door your purchase should have a U-value of 1.8W/m2K or less.


The price of a bifold door is of great importance as it informs just what type of door you can get.

Generally speaking, bifold doors aren’t the cheapest things to buy, with the most affordable one’s going for well over £1000.

In fact, some of the high-end brands could go for as much as £6000 or even beyond.

It all depends on your budget, and uPVC bifold doors are the easiest to lay your hands on.

Unfortunately, uPVC doesn’t last as long as some other materials like aluminium, which could easily serve you for decades.

That said, carefully review your budget to ensure you can afford the door on your mind and also take into consideration the cost of installation.


While bifold doors are sometimes considered expensive, they also last so long that they are worth it.

However, to ensure that your purchase is risk-free, it is crucial to check what sort of warranty the product comes with.

Origin, one of the most respected bifold door companies in the UK, backs their products with a 20-year warranty, which is very attractive.

In addition, ensure you confirm what the warranty covers so that you aren’t left slack-jawed when you discover that your warranty doesn’t cover the damage incurred.

Flexible configurations

One of the most important things to pay attention to when getting a new bifold door is how flexible it is.

For instance, if your home has an opening size of 1.4 meters, you should be fine with a two-door configuration.

On the bright side, bifold doors are quite versatile, and while no two homes use the same configuration, you can at least be confident that you’ll find something that works.
