While Bi-folding doors can be fitted onto many different kinds of walls, including interior and exterior brick walls of your main property, bi-folding doors are very popular additions to extensions and conservatories.
Made up of multiple glass panels that can stretch as long as an entire wall, bi-folding doors fold back in a concertina shape to open up your conservatory to your garden, folding up against the far wall for discrete and unobtrusive storage.
Once opened, the throughway to your garden is easily accessible for everyone, even buggies and wheelchairs, with its low threshold.
Because of this, if you have a conservatory that extends out into your garden, fitting a bi-folding door is a great alternative to a back door.
With slimline frames maximising the amount of glass per panel, these bi-folding doors allow for large amounts of natural light to enter your property, and, even when closed, provide an outstanding panoramic view of your garden and outside areas.
If you have a conservatory for your property and are looking for an alternative to your old uPVC back door, bi-folding doors are a way of providing your home with a far grander entrance, and natural light and ventilation.
One of the main features of a conservatory is as a sunroom, the glass panels allowing for as much natural light to enter your property as possible.
Patio doors can be rather restrictive, with only one sliding section of glass, bi-folding doors allow for you to open up an entire wall out into the garden.
This can be especially beneficial for families who want to feel more connected to the garden, or for people with mobility issues who may struggle to get over the threshold of typical back doors.
Even when you are inside your property, you will be able to benefit from the large amounts of natural light and fresh air coming in through the open doors.
If you are concerned about the security of these doors, then don’t worry.
When closed, bi-folding doors are incredibly sturdy and hard wearing against both harsh weather and anyone trying to gain entry to your home.
Most installation companies offer a multi-point locking system as standard, as well as additional options including internal beading and steel reinforcements to help protect you against any potential break-ins.
With such large areas of glass, you may be concerned that your new bi-folding doors may not be very thermally secure, but that couldn’t be farther from the truth.
When opened, bi-folding doors may be able to provide your house with cooling ventilation during the summer, but they are also incredibly thermally efficient.
When closed, their strong and durable double glazing and frames prevents warm air from escaping and stops any cold air from coming in.
Conservatories are meant to be enjoyed all year round, but poor insulation can make them hard to spend time in during the winter.
However, with bi-folding doors’ superior insulation your home will be able to remain warmer for longer, saving you money on your heating bills and even helping you to decrease your carbon footprint.
Also, with their large areas of glass, any sunlight will be able to get through into your property, its warmth being trapped within your conservatory so you can enjoy the views even on cold winter mornings.
If you have noticed that your conservatory is becoming colder, it could be a sign in a flaw in either the doors or roof.
While the typical brochure image of a bi-folding door is one that stretches for the entire wall of a room, bi-folding doors can also be made to fit much smaller spaces.
In fact, it is quite easy to get a bi-folding door that fits the same dimensions as a patio or French door.
As measured in our quotation cost calculator, the minimum size for a bi-folding door is 1500mm x 1000mm (1.5m x 1m), while the maximum dimensions are 9400mm x 2500mm (9.4m x 2.5m).
However, some installers do allow for a minimum width of around 1400mm. This adaptability in its design allows for bi-folding doors to be fitted onto any kind of property or conservatory, even if it is relatively small in size.
The number of separate individual panels you can have for your bi-folding doors depends on its size, with the smallest dimensions only allowing for two folding panes, while the largest size allows for up to eight.
In terms of customisability, even the smallest dimensions allows for a few different options in orientation for the windows and door sections.
This allows you to choose from folding to the left or right or having the window and door sections separated, allowing you to easily enter and exit your garden without having to open up the entire series of panels for a quick trip outside.
Bi-folding doors are able to come in two different materials, uPVC and aluminium. uPVC, standing for unplasticised polyvinyl chloride, is a hardened resin that is an incredibly popular material for windows and doors.
It is likely that either you or your neighbour may have some kind of uPVC product installed.
With a lifespan of up to 30 years, they do not suffer from the same natural wear and tear of timber frames and are incredibly easy to maintain, only needing an occasional wash in order to keep them looking great.
uPVC bi-folding doors are a great way of matching your uPVC windows, especially if you are having it installed onto a uPVC conservatory.
However, you won’t have to worry about any chunky white frames obscuring your view. uPVC bi-folding doors are made incredibly slimline so as to maximise the amount of glass per panel and keep a great unbroken view of the outside.
They are also incredibly personalisable not only able to be coloured in a range of natural tones and bright colours but also offer a woodgrain finish that replicates a traditional wooden window frame without any of the additional sanding, varnishing or repainting.
Like uPVC frames, Aluminium bi-folding doors are also incredibly durable and long-lasting, but with a far longer lifespan.
Lasting around 40 years with little to no upkeep aside from the occasional wash down, aluminium frames are a great, modern alternative to uPVC.
Thermally efficient and highly secure, these metal frames are able to withstand years of hard use, exposure to the elements and any attempted break-ins without failing.
Aluminium bi-folding doors are able to suit both contemporary and period homes, especially those that wish to draw attention to pre-existing features.
Able to be coloured any RAL colour on the wheel, aluminium frames don’t need a woodgrain finish to suit a traditional properties, with a smooth and sleek finish that is able to fit nicely alongside traditional masonry and woodwork.
Like uPVC, aluminium bi-folding doors come with a multi-point locking system fitted as standard and can come with additional internal beading and steel reinforcements to help protect against anyone trying to force their way inside.
While uPVC needs to be manufactured using chemicals, aluminium is made from a naturally occurring metal that is easy and safe to manufacture, making it far more environmentally friendly.
If you are interested in getting a bi-folding door for your property or your conservatory, you may be wondering just how much it will cost.
Bi-folding doors look highly fashionable and very modern, so it is easy to assume that they would cost you an arm and a leg; however, they are actually very affordable.
While, like all home improvement installations, the cost does often depend on size, there are other factors to take into account; for instance, how many separate panes there are and what material they are made from.
A uPVC bi-folding door has a starting cost of around £1,950 and can cost up to £3,900, depending on the number of panes.
Meanwhile, an aluminium bi-fold door costs a little bit more than its uPVC counterpart, with a starting price of around £2,300 and going up to £6,500.

Conservatories are not the only place you can put a bi-folding door.
Orangeries are becoming an increasingly popular option for home improvement installations, being an affordable compromise and combination of the best parts of both a conservatory and an extension.
Originating on 17th-century estates as a way to house citrus plants during the winter, orangeries are considered by planning regulations to be the equivalent of a conservatory, allowing for them to be easily built without the requirement of planning permission.
As orangeries are predominantly built from brick, rather than a conservatories uPVC, having a bi-folding door installed onto an orangery is just as easy as having it installed onto your main property.
