External doors: Bifold doors vs sliding doors

When you’re looking for ways to make your home lighter and to create the feeling of more space, one of the best home improvement ideas is to fit external doors that incorporate glass panels. Both bifold doors and sliding doors fall into this category.

So, how do you choose between these glass-panelled, durable but decorative doors? This guide looks at the pros and cons of bifold doors vs sliding doors.

What is a bifold door?

A ‘bifold’ refers to a door that has a concertina effect when opened. It folds in on itself to allow you to walk through the doorway. It is often used as a room divider too (internal bifolds), as the doors can be easily opened to create one open plan living space.

External bifolds are built to look stunning but also to provide important energy-efficient values. Vufold’s composite bifold door range offers some of the best thermal efficiency on the market.

How do bifold doors work?

Bifolds come in a range of sizes and materials. They operate along a track system that ensures they can be effortlessly opened and closed.

The track system involves the doors (or leaves) being fitted to runners that run along the track system. As the doors run along the track, they fold at the same time to create a seamless operation. The doors stack at either end of the door creating a wide opening.

All bifold doors require a main track and a guide track to operate. You can variations of track systems such as top-hung and bottom rolling:

  • Top hung- the bifold doors hang from rollers with the main track located in the frame head.
  • Bottom rolling- the main track is located in the sill/threshold at the bottom of the frame.

Amazing views

Installing a bifold doors means you get to showcase your beautiful garden or other features. Installing a bifold with thinner thresholds means more glass and even better views! Aluminium bifolds offer some of the thinnest sightlines around.

More natural light

With more glass comes more natural light. You can illuminate a dark kitchen or other interior with a new bifold door. Combining a bifold door with a matching window means even more light while keeping the style consistent.

Fantastic flexibility

Bifold doors offers flexibility in usage few other doors can match. You have the option of open the entire door for maximum impact, or simply use the traffic door for normal usage. A traffic door is a panel (or leaf) that can be open and closed like a regular door. If you plan on using your bifold door often, you should consider a traffic door.

Variety of materials

Bifold doors can come in a variety of materials such as:

  • Aluminium– a popular bifold that offers the thinnest sightlines.
  • Timber– a combination of natural aesthetic and excellent thermal efficiency.
  • Composite– combining the strength and durability of aluminium and the natural thermal efficiency and beautiful aesthetic of timber.
  • UPVC– a cheap alternative.

Cons of a bifold door

Bifold doors offer many benefits. They also have some considerations to make:

  • May need to stack inside the home– most external doors can be stacked outside the home, meaning you don’t lose any space. However, if the outside space doesn’t have much room (like a small balcony etc.) you may need to ensure there is space inside the home so the doors can open inwards.
  • Can be more expensive– with the amount of engineering required and the quality of the doors, it should be unsurprising to find that bifold doors can be more expensive than standard patio doors. However, this is not always the case, and you should take your time in researching the best prices.

What is a sliding door?

Like a bifold, sliding doors move horizontally along a track. However, with a sliding door, the moving panel simply sits over a static panel.

Sliding doors often utilise larger leaves (panes of glass) which offer wide, uninterrupted 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.

Advantages of a sliding door

Sliding doors offer many similar benefits to a bifold door, such as:

  • Stunning views- with wide panes of glass, sliding doors offer uninterrupted views.
  • Natural light– with wide panes comes plenty of natural light!
  • Easy operation- sliding doors simply move along a track and stack on top of each other.
  • Feeling of space– like bifolds, sliding doors have the ability to ‘bring the outside in’ meaning a flow between indoors and outdoors can be created.
  • Excellent security– again, like bifold doors, quality sliding doors will be made from a type of security glass and utilise a multipoint locking system.

Disadvantages of a sliding door

Like anything, sliding doors come with some downsides. This section details the main ones to consider.

  • Unlikely to open fully– due to the operation of a sliding door, there must be a static pane of glass that the operational pane sits on top of, meaning you cannot fully open the space. However, due to the large panes used in sliding doors, you will still get a wide opening and an excellent inside/outside flow.
  • Bottom-rolling– due to the weight of the panes, sliding door roll along the bottom sill. Generally, top-hung doors are considered superior due to easier operation and less maintenance. However, bottom-rolling is still a very viable option.

Bifold vs sliding doors

Choosing between a bifold door and sliding door does not come down to ‘which is better?’. Both doors offer a range of benefits and can suit almost any home. It all comes down to buying the best door to match your layout, lifestyle and preferences.
