Bi fold doors

When it comes to doors, you want something that will open up space with an aesthetic appeal to complement any home and room. Doors are an important feature and finishing touch, so a considered decision is needed.

With bifolding doors you have class and a modern appeal that can’t be matched by the traditional patio or French designs. Whilst they’re often seen with two panels, there can be more, connected by centralised hinges for ease of operation.

Bifolding door panels are pushed together before being folded to one side, making the most out of space available.

In this step by step guide, we’ll take you through the bifold doors installation process.

The first step to take when it comes to bifold door installation is to take the measurement of the door opening and get a kit in the appropriate size.

How do bifold doors work?

How Do Bifold Doors Work

Generally, bifold doors are modern styled doors that are able to create a grand entrance and catch any visitor’s attention almost immediately. Unlike the conventional sliding doors, they are way more practical and convenient which makes it an awe-inspiring home addition. However, with the design being relatively new when compared to its counterpart - the sliding doors, not everyone knows about how they work. Therefore, it’ll only make sense to discover more about this door design before deciding on its utility. So how does a bifold door work?

The bifold door ( both interior and exterior types) operates on a built in tracking system that runs along the glass panels and connected on a train. In other words, the doors fold in and then slowly and smoothly glides over the laid out track which is backed by a chain of wheels or a tracking system. This function is carried out in a smooth and quiet manner, irrespective of the medium of movement.

Now talking of the bifold structures, they mostly come in pairs especially the interior designs. The design can either be in form of two doors that can be folded to one side or four individual panels that can be opened from the centre while some of the doors will fold on each side. Typically, the tracking will feature these units as well as the other important fittings, and also open inwards or outwards.

One of the significant qualities of these doors making them a popular option amongst homeowners nowadays is the flexibility and versatility of these units as well as their effectiveness when it comes to saving space. You’d be surprised to know that some of these bifold door designs can feature up to 7 panels which are linked via hinges and connected to the top or bottom of the roller track.

How much are bifold doors?

How Much Are Bifold Doors?

Are you considering installing bifold doors for your home or property? If yes, then you’d probably want to know how much it would cost so you can prepare a budget and start planning. The cost of bifold doors, however, is dependent on a wide array of factors which includes the number of panels, size of the bifold doors, internal or external installation, material used in making the bifold doors, type of the glass as well as upgrading the locking mechanisms.

Of all these factors, the most significant influences are both the material and the number of panels to be used. For bifold doors with 3 panels, the potential cost will range from £1,200 to £2,500 depending on the materials used, be it aluminium, timber or uPVC. For a 4 panel bifold door, the price will range between £1,400 to £2,800 depending on the either of the three aforementioned materials. And finally, for a 5 panel bifold door, the cost will be between £2,500 to £5,500, also depending on the three materials.

When calculating the cost of bifold doors, it’s also important to factor in the cost of installation as the task requires specialized skills and tools, therefore it’s not advisable to be made a DIY project. The cost of installing a bifold door will also be influenced by multiple factors such as the bifold door material, the number of panels, your location in the UK, the installer of your choice as well as whether or not there’s an existing opening that’s suitable for bifold doors. The price will ultimately boil down to the installer you hire, so it’s advisable to contact multiple professionals and compare their services and quotes. For the easiest installation where there’s an existing opening in the wall, the price will range between £150 to £500. However, for more complicated installations, the price could be above £500.

Are bifold doors secure?

While some people may see bifold doors as insecure, many bifold doors feature advanced security measures. Internally beaded strengthened double glazing is very secure. Choose a bifold door with a multi-point locking system for enhanced security. If your house is empty for long periods, always consider a blind solution to keep prying eyes out of your home.

What is the smallest opening for bifold doors?

What Is The Smallest Opening For Bifold Doors?

Generally, bifold doors comes in a wide range of sizes and configurations. So if you’re looking to install them in your home, the opening size required will depend on multiple influencing factors. However, the question we’re going to look at here is the smallest opening for bifold doors.

First and foremost, let’s consider the size of bifold doors as learning about how big or small bifold doors can play a key role in helping you determine the size of bifold door you’ll need. Generally, the size of bifold doors will vary largely depending on the manufacturer, but they are usually within the range of 6.8 feet and 7 feet in height. The width, however, will be determined by the number of door panels you’d like to use but several configurations are designed in such a way that they can be installed in openings of about 1.8m and above. For each door panel, the size are usually between 500 and 1000mm in width. As a result, if you decide to opt for door panels with a width of 700mm, you’ll need to get about 3 of the door panels in order to install in an aperture that’s wider than 1.8m. What’s more? Door panels can also be custom made especially if the size you need isn’t available.

So with that in mind, what’s the smallest opening for bifold doors? The bifold door’s minimum width is 1400mm. And in order to install a bifold door to fill this size, you’ll require two individual door panels that’s 700mm in width. Building them any smaller than the minimum width will be unwise as this will make them bind when closing.

Will I need a traffic door?

Traffic doors are doors which open like an ordinary door. They are contained within the bifold door configuration. It’s recommended to fit a traffic door if you intend on using your bifold door as the main access point to your garden. If you are considering an installation, ask the installer about the benefits.

Do bifold doors fold back flat?

Do Bifold Doors Fold Back Flat?

Bifold doors, also referred to as folding doors, have grown to become a great alternative to the conventional sliding doors. It has become a necessity rather than a luxury for most home and property owners especially in the south east who are in need of more space and a memorable focal point. However, before installing the impressive bifold doors in your home’s doorways, it’s always a wise decision to learn more about bifold doors. In this article, we’ll let you whether or not bifold doors fold back flat.

Generally, bifold doors consists of 3 to 8 door panels, bifold slides and fold back against one another in such a way that they sit flat against one or both walls. However, this depends on how they’re designed, whether they’ve been designed to open either from the side or from the middle. They basically work on what’s popularly referred to as a concertina principle. This style fold principle works in a way that allows the door panels to smoothly fold back flat which totally opens up the room into an open plan masterpiece.

So now that you know that bifold doors fold back flat, you may also be curious to know whether they also open in or out. Depending on your specific requirements, bifold doors can actually open inwards and outwards independently. However, due to the fact that opening bifold doors can take up some essential space, several home and property owners do prefer installing their bifold doors in such a way that allows it to be opened outwards. What’s more? It’s also essential to take into account that opening bifold doors inwards have the potential to drip water onto internal flooring especially for the wet regions.

Do bifold doors open in or out?

Do Bifold Doors Open In Or Out?

If you’re considering getting bifold doors, then you’d probably want to know if it’s going to open inwards or outwards. The answer to the question is both, it can open inwards or outwards. Generally bifold doors are configured with flexibility in mind. They’re designed in such a way that allows them to be opened inwards or outwards depending on your preference or what best suits the space on which they will be installed. As a result, when you’re considering the installation of new bifolding doors in your home or property, one of the things you’ll have to take into account is whether you want your bifold doors to open inwards or outwards. Below are a couple of tips that’ll help you make the best decision as to whether your bifold doors should open inwards or outwards.

• Where you’re going to fit your bifold doors can play a huge role in determining whether they’ll open inwards or outwards. For instance, if they’re going to be fitted in your dining room, the furniture you have there will determine if there’s enough space to accommodate them inside or otherwise.

• The frequency of use will also be an influencing factor. If the door is frequently used, then a bifold door set with a traffic door which opens outwards will be more convenient for heavy daily use.

• The size of your outdoor space. Is your outdoor space restricted by your patio’s size, the decking area or garden? If yes, the opening inwards would be the best option. So also if your door opens straight out onto a pathway, you might want to make the bifold doors open inwards as well so as not to block the path.
