When you are making home improvements or looking for the perfect patio door, choosing the right door type for your home and needs is extremely important. Any glass door, whether bifold or sliding, forms a focal point for your home, as well as protecting you from the elements and maximising security. Making the right choice is essential but, with so many variables and a wide number of choices available, it can be difficult to know where to start.

Two of the most popular options for external and patio glass doors are bifold and sliding doors. Our guide will help you to compare the costs and benefits of each type of door to help you decide which door system is right for you.

What is a bifold door?

Bifold doors consist of a set of large glass panels that fold back on themselves in a concertina effect. This characteristic means they can open up an entire wall, so they are perfect for homeowners who are looking to create a seamless transition between rooms or between your home and patio or garden area.

Bifold doors are fitted to runners, which they slide along when opened. Each door leaf then concertinas, or stacks, together. Most door sets have top and bottom runner for optimum rigidity. External bifold doors always operate using a top and bottom track however, internal bifold doors can be built to function without the bottom runner, to remove the need for a bottom track.

Some sets of bifold doors have a traffic door, so you do not have to open the entire set of doors every time you require access. This function is great for anyone with pets or children.

A oak bifold door will provide a traditional look while maximising space. On the other hand, you may want to create a more modern feel and bifolds make this easy with an aluminium bifold door or composite bifold door options that offer exceptionally slim sightlines and an up-to-date look.

The benefits of bifold doors

The key benefits of a bifold door include:

  • Flexibility in style
  • Super low weather rated thresholds
  • Seamless transition between indoors and outdoors
  • Great visibility
  • Range of materials and finishes available
  • Available ready-to-assemble – be sure you’re buying from a manufacturer that offers a fully finished product
  • Available with both double and triple glazing options.

Alongside the benefits, bifold doors also have a few drawbacks which must be considered:

  • Frames can obstruct your view, although sightlines are getting slimmer all the time
  • May need to be stacked inside, which could compromise.

Sliding doors in a bedroom

As the name implies, sliding doors work by sliding along a track. There are two types available:

  • Traditional inline door – this door slides within its frame
  • Lift and slide doors – this door allows for larger glass panels and offers top-level thermal performance

Unlike the traditional sliding door that simply slides along a track, Lift and Slide doors work by using a handle that you simply turn to lift the door onto its rollers. This means you can be sure the door is always in the optimum position and has allowed for the development of sliding doors with larger panels.

Sliding patio doors are popular with homeowners seeking a contemporary edge to their home design and look great in any modern home extension, making the transition between the home, garden, patio area or any outdoor space seamless.

Benefits of sliding doors

Sliding doors offer a number of benefits including:

  • Large panels for optimum views
  • Slim aluminium frame provides thin sightlines
  • Sleek, modern style
  • Super low weather rated thresholds
  • Top-quality thermal efficiency
  • Superior security
  • Available with both double and triple glazing options

Compared to bifold doors, sliding doors have a few drawbacks that should be considered before making the choice between the two types of doors. These include:

  • Do not open fully, unless you have a design that slides into the wall – there is usually one static door panel
  • No traffic door
  • Aesthetic compromise for traditional style homes

Bifold doors often have a reputation for being the most expensive option when buying patio doors. But, due to an increase in costs in material, sliding doors are now more in line with prices of bifold doors; however, Vufold are able to mass produce and carry lots of stock when it comes to bifold doors. This has allowed us to keep the pricing down. Due to the larger and heavier glass and door panels used on sliding doors, it is more difficult to mass produce and store sliding doors.

What other factors should you consider when choosing between a sliding door and a bifold door?

In addition to considering price, key considerations such as the style of your home, how you will be using your doors throughout the year, as well as practical aspects including ease of use, security and thermal efficiency, should all work alongside price to inform your decision. Sliding doors often utilise larger leaves (panes of glass) which offer wide views. The stacked system saves space. However, the doors cannot be ‘fully opened’ as one leaf has to be sitting on top of the other. With bifold doors, however, you have the option of opening the entire door for maximum impact, or simply using the traffic door for normal usage.

Before making your purchase, it is also worth bearing in mind that Vufold bifold doors are also ready-to-assemble. This means that the doors are pre-machined and come with almost everything you need for installation, including:

  • Tracks
  • Hinges
  • Hardware
  • Glazing
  • Fixings

Only a few standard tools will need to be sourced for installation. Find out more about Vufold’s ready-to-assemble bifold doors here

You should also bear in mind the space you have available for each option, and which opening mechanism you prefer. For example, if the outside space doesn’t have much room (like a small balcony etc.) for bifold doors, you may need to ensure there is space inside the home so the doors can open inwards. Consider that in sliding doors, because of the weight of the panes, sliding doors roll along the bottom sill. Generally, top-hung doors are considered superior due to easier operation and less maintenance.
