Bifold Doors or Sliding Doors? The Pros and Cons

22 Aug - 2025

When choosing between bifolding and sliding doors, there are several things to consider. Both have many practical and aesthetic benefits, but there are some notable differences between the two. The decision ultimately comes down to what you want your doors to achieve.

Do you want to give yourself a better view of your outside space? Do you want to increase the amount of natural light in your property? Or do you want to improve the way you and your family use your home and garden? To help you decide, we have compared the two across a range of key categories, listing the pros and cons of each and which style of door we believe comes out on top.

Bifold vs Sliding Doors: Opening Space

Folding Doors

Bifolding doors have a wider opening than sliding doors when fully folded, which means that the home and garden can be integrated more seamlessly. This is because the panels of a bifold door fold back (or concertina) to a stacking point, creating an unobstructed view of the outdoors. Many people find this kind of visibility desirable, so this is definitely something to consider when weighing up your options.

Sliding Doors

When in operation, sliding doors have a smaller opening than folding doors, which reduces accessibility between home and garden. That said, this attribute makes them a popular option for properties with less room, especially as bifold doors require more space to create the larger option. Unlike bifold doors, sliding doors overlap, which reduces the amount of space needed for them to open.

Result? Bifolds win

Folding doors take the easy win in this category – these doors are perfect for homeowners who want to integrate the beauty of the garden with their home and extend their living space. Despite this, sliding doors do have their benefits and are a positive addition to homes with less space and smaller gardens.

Bifold & Sliding Doors: Practicality

Sliding Patio Doors

Generally speaking, sliding doors move easily on their tracks and open with minimal effort. This will continue if you keep them free from debris and lubricate them regularly. As mentioned above, as sliding doors don’t swing open, they require less space than bifolds, a useful trait for those with smaller homes.

Bifolds

If you have bifolds installed, you will have to keep an area clear for the doors to function, which can be impractical for smaller rooms and gardens. A traffic door can be included in the design to ensure easy access in and out, just as you would with a back door. This can be particularly useful in the colder weather. The ability to have a level threshold between inside and out will completely transform your home, opening out your space to its full capacity.

Result? Draw

Bifolding doors' ability to open fully increases their practicality, however, they do require an external or internal area for the doors to be stacked. The versatility of traditional sliding doors means they are suitable for any-sized room, despite letting less of the outside 'in'.

Bifold & Sliding Doors: Glass Sizes

Sliding Patio Doors

The traditional sliding style offers a larger glass surface and narrow frames, meaning that when the door is closed, you'll enjoy a wider and more panoramic view of your exterior environment. Once open, sliding doors create a half opening, allowing for a gap wider than your standard door.

Bifolding Doors

The maximum width for each panel is increased with bi-fold doors, offering improved views and letting in more natural light. However, the framework needed for this style of door is typically wider than traditional designs, so the exterior view may be affected when the folding doors are closed. This is compensated by the ability to fully open the space in which the doors sit.

Result? Sliding doors win

Sliding doors are the winner here, as they offer a larger glass surface. Whilst our folding products are designed with slim sightlines, many customers choose sliding doors over folding doors to make the most of their property's outside views.

Bifold or Sliding Doors: Thermal efficiency

Sliding Doors

Generally speaking, sliding doors offer greater thermal efficiency than their folding counterparts. This is because they have smaller profiles and less frame space, minimising the chances of cold air entering properties and heat escaping from them.

Bifold Doors

While it's true that sliding doors are more thermally efficient than bifolds, the difference is marginal. This is because of the inclusion of thermal break technology in many types of modern aluminium doors, which minimises the transfer of cold and heat between inside and out.

Result? Sliding doors win

While sliding glass doors have traditionally guaranteed improved energy efficiency, advances in technology have allowed bifolds to catch up in the heat retention stakes. This means that the difference between the two is now almost negligible, so you are free to choose the style of door that best suits your requirements without worrying about how this will impact your energy bills.

Bifold & Sliding Doors: Adding Value

Bifolds

Always increasing in popularity, bifold doors can add a modern twist to your home. They produce a better visual appearance than sliding doors and are likely to increase the value of your property. Newer builds and larger homes tend to have patio areas readily available, allowing for the flat threshold effect of bifold doors to become the centre-piece of the rear of your house. If you're looking to create the ultimate summer space, opening up the back of the house to connect with a garden or patio, bifolding doors offer the chance to create a complete opening that sits flush with your outdoor environment.

Sliding Doors

Sliding doors add beauty and elegance to a home and can effectively increase the amount of natural light that filters into your space, making smaller rooms feel bigger. Uninterrupted views of the garden, increased access to the outdoors, and more light are all key benefits of sliding doors.

Result? Draw

Both door options effectively improve the look and functionality of a home, easily increasing a property’s value when it comes to selling up. Additionally, each Lite Haus door is designed to be thermally insulating, an important consideration for anyone purchasing their next home, improving your energy rating, and ultimately adding greater value.

Bifolds and Sliding Doors: Security Features

Bifolds

Installing a set of aluminium bifold doors shouldn't be disregarded because of safety. Bifold doors come with multi-point locking and inline systems, making it impossible to accidentally or intentionally lift the doors from their track.

Sliding Doors

Similarly, our sliding doors come with a multi-point locking system and inline tracking to ensure the doors can't be lifted. The addition of double or triple glazing will also make the doors more secure, as well as bolster their thermal and energy efficiency.

Result? Draw

With both styles as secure as each other, there is no need to worry about the security of your bifold or sliding doors. Our multi-point locking systems combine with inline tracking to ensure the safety and security of your property for many years to come.
