External bifold door locations: patio, kitchen, extensions and summer houses

External bifold doors can make a huge difference in many areas of your home. In this guide, we will look at the most common areas you will find bifold doors.

Main areas for external bifold doors:

Patio doors

Patio doors are an excellent way to show off your garden, whilst also providing easy access. However, ‘patio door’ is a catch-all term that refers to three types of doors:

  • Bifold doors - a system of multiple doors that fold back on themselves when opened, to create a concertina effect. Bifold doors are built on a track system that allows the door to roll and fold in one seamless operation
  • Sliding doors - opens horizontally along a track. They are made of the largest leaves (panes of glass) to offer uninterrupted views 
  • French doors - two doors that pivot on hinges mounted on opposite sides of the door framing

Kitchen doors

Bifold doors can transform any kitchen into a bright, airy and beautiful room. In this section, you will find a brief list of kitchen bifold door benefits and considerations.

Benefits of kitchen bifold doors

  • More natural light - bifold doors can fill your kitchen with natural light, giving it a bright and airy appearance
  • Great views - show off your garden or view with a large bifold door.
  • The feeling of space - bifolds can make your kitchen feel larger by bringing in more natural light and offering a view of the garden
  • Blends outdoor and indoor spaces - when open, bifold doors offer uninterrupted space between the interior and the garden, perfect for BBQs and garden parties

Consideration for kitchen bifold doors

There are some key considerations to make when purchasing kitchen bifold doors. In this section, you will find some brief information on these considerations.


Boiling liquids creates water vapour which turns to condensation when it makes contact with something cool, such as a windowpane. In a kitchen, it’s unavoidable to create water vapour when you’re cooking. Instead, you should ensure that your kitchen is as well ventilated as possible.

Top tips to keeping your kitchen ventilated:

  • Purchase an extractor fan above the cooker
  • Try to have a window installed in the kitchen, as well as your bifold.
  • If you are unable to have an additional window installed, ensure that your bifold have trickle vents (a small opening that allows some ventilation)

Energy efficiency

An energy-efficient bifold door ensures your kitchen stays properly insulated. A well-insulated kitchen stays cool in the summer and warm in the winter. To check your bifold door’s energy efficiency, you should look for the U-value. The U-value measures how effectively a material insulates a room.

The lower the U-value, the better the insulation.

U-value and building regulations

The current building regulations for new dwellings (approved document L1A) state the overall U-value of a glazed door (bifold) should be 1.4 W/m2 or less. For existing dwellings (approved document 1LB), the value should be 1.8 W/m2K or less. Vufold bifolds have an overall U-value as low as 1.0 W/m2k (Vufold Ultra range).


Glazing can affect the insultation properties of a bifold door. There are three types of glazing:

  • Single glazed – this is just a single pane of glass. You are likely only to find them on listed buildings where double or triple glazing is not allowed to be installed
  • Double glazed – created by taking two glass panes and separating them with a spacer bar. The gap between the panes traps heat which slows energy loss. Double glazing is the most common type of glazing
  • Triple glazed –the most thermally efficient type of glazing. Uses the same technology as double glazing but includes an extra pane for added thermal insulation

Bifold doors for extensions

Bifold doors can suit almost any extension. Different extensions require different considerations. In this section, you will find the main types of extensions and the specific considerations you need to make.

The main types of extensions are:

  • Bedroom
  • Living/dining area
  • Conservatory
  • Small

Bedroom bifold doors: ground floor or top floor?

The location of your bedroom will define the type of consideration you need to make and the bifold that will suit your bedroom.

  • If your bedroom is on the ground floor – you will likely want the bifold doors to lead into the garden. You may want access without having to open the entire bifold. A traffic door means that you can open a single door without having to operate the entire bifold
  • If your bedroom is on the top floor – your bifold doors will lead out onto a balcony. If you have a large enough balcony, we recommend your door opens outwards. However, if you have a small balcony, we can supply top quality bifolds that open inwards but make sure you consider the space requirements

Living room / dining area bifold doors: light and blinds

living room doors

One of the main benefits of bifold doors is that they bring a lot of natural light into a living space. However, you may want to consider blinds for the living room. On a sunny day, you may find the natural light will cause a glare on a television screen.

Vufold’s specially designed blinds fit theMaster and Elite bifold ranges perfectly. Alternatively, the Status range can be installed with integral blinds fitted between the panes of glass. This ensures that you can enjoy natural light when you want it, and block it out when you need to.

Conservatory bifold doors: top hung or bottom rolling

When bifold doors are called top hung or bottom rolling, it is referring to the track system. Every bifold has a main track that they operate on – either in the door frame head (top hung) or bottom threshold (bottom rolling).

Top hung has many benefits including smooth operation and low maintenance. However, it does require added support with a lintel. Most conservatories will not be able to support a top-hung bifold.

Many standard bifold doors which are bottom rolling can end up getting blockages in their man track causing poor operation. However, the Vufold Status range utilises a sealed outer frame that helps stop debris from falling into the main track. This stops any blockages and ensures smooth operation. The Vufold Supreme range has removable track cover, self-cleaning bottom roller and is fully adjustable, for smooth operation.

Bifold doors for small extensions: traffic doors

Traffic doors provide easy access between areas without having to operate the entire bi-folding doors. This can save you time and effort in operating the door.

We recommend traffic doors if:

  • The bifold doors offer the only access to the garden
  • Your bifold doors are based in a high traffic area and require frequent use
  • If you live with small children and/or elderly people who may not be able to operate the full bi-folding door properly

If you are considering purchasing a bifold with a traffic door, we recommend a minimum of a three-door bifold of 1.8 – 3.0 metres.

Summer house doors

A ‘summer house’ (also known as garden rooms and garden spaces) are typically buildings used for relaxation in warm weather. However, with modern insulation methods, summer houses can be used for a variety of reasons.

In this section, you will find information on popular uses for summer houses and bifold considerations to make.

Popular uses of summer houses include:

  • Event hosting space
  • Garden office
  • Home cinema
  • Multi-purpose

Event hosting space

If you enjoy putting on a meal for your friends or hosting BBQs in good weather, a summer house offers an excellent space. You can turn your summer house into a dining area with stunning views of the garden and some fresh air.

If you want to showcase your garden with uninterrupted views, you should choose bifold doors with thinner sightlines.

Garden office

As more people turn to freelancing garden offices are becoming more popular. They offer a space that is separate from the house to reduce distractions.

Garden offices can suit any bifold doors. You should consider a traffic door if you are planning to use the garden office daily.

Home cinema

There are several benefits of having home cinemas that are separate from the main house. The main benefit being that you can enjoy a loud movie without disturbing the rest of the house. The home cinema can also double-up as a lounging area during the summer months.

Blinds are very important for home cinema’s, to reduce any glare. Vufold offers blinds specifically designed to fit their Master and Elite ranges. Vufold also offers integral blinds for the Status range which can be fitted between the panes of glass for a stylish design.


Summer houses are often used for multiple purposes. In the day, a summer house might be a garden office, in the evening, a dining space.

Text BoxBifold doors offer flexibility for all these spaces by adapting for almost any situation.
