Aluminium Bifold Doors vs Aluminium Sliding Doors

Sliding Door

Large glazed doors are a desirable addition to properties and with so many products on the market, it is good to discover the pros and cons of each.

Choosing between aluminium bifold doors and aluminium sliding doors inevitably comes down to personal preference and what will work best with your home, both practically and aesthetically. Learning the difference between the two products is key to choosing the right one for your home.

Aluminium Bifold Doors

aїr 800 bifold doors are the Rolls Royce of aluminium bifold doors and have been exactly engineered to create open expansive spaces with impressive performance. They are available with up to 10 door panels each measuring 1.2 metres wide and 3 metres high, creating the opportunity to convert large walls into open spaces.


Aluminium Sliding Doors

aїr 500LS and 600LS lift and slide doors offer you easy access in and out of your home. The panels of glass weighing up to 300kg can be moved effortlessly with as little as 2 fingers thanks to the impressive aїrglide technology and strong rollers, creating an impressive feature wall of glass and flood living spaces in natural light.

Key differences between bifold and sliding doors

Although each door system holds the same benefits as the other, aspects of one product may be more suited to your home. For example, the opening or the size of the glass panels. Ultimately, one will offer characteristics that are best for your home, without having to compromise on features.

Although bifold and sliding doors have a different design, each door still shares features that offer captivating aesthetics and impressive performance.


Both aїr 800 bi-folding doors and aїr lift and slide doors achieve the latest requirements for enhanced security performance without having to compromise on style. With innovative security features, such as high security locking, PAS 24 and the police approved Secured by Design accreditations, homeowners have peace of mind when it comes to the security of their family.


As well as having hundreds of RAL colours to choose from, homeowners have the additional option of choosing an aїrcoat textured finish, for both bifold and sliding doors, that creates a durable scratch and dirt resistant surface, to keep doors looking as good as the day they were installed.

Both designs have a dual colour frame option to give complete flexibility when it comes to matching the interior and exterior of homes. The only difference is that bifold doors can be designed using any RAL colour. However, sliding doors have the limitation of choosing from 400 RAL colours.

Size of Glass Panels

aїr sliding doors boast large glass panels for doors up to 15m wide in comparison to bifold doors which have a smaller maximum width of 12 metres. Unsurprisingly this means that the large glass panels in the lift and slide doors provide a larger unobstructed view regardless of whether the doors are open or closed. On the other hand, aїr bifold doors have a taller maximum height of 3 metres compared to sliding doors maximum height of 2.7 metres, so depending on the style of your home, this extra height could be beneficial.

Sliding Doors


Regarding obstructions of view, aïr 800 bifold doors are able to have sightlines as slim as 108mm. However, aïr lift and slide doors boast sightlines that can be as slim as 48mm, meaning that sliding doors offer the best uninterrupted panoramic view from your home to your garden. If space is limited, aluminium sliding doors also take up less room in contrast to aluminium bifold doors when open, so can be a more convenient option.

Energy Efficiency

aïr lift & slide doors offer U-Values as low as 0.95 W/m2K, as well as Teflon®-coated weatherseals, watertightness to 600 pa and extreme wind-resistance up to 1200 pa. You can even opt for triple glazing, which helps give peace of mind that your home is secure as well as thermally insulated. In comparison to this, aïr 800 aluminium bi-fold doors have wind resistance up to 1800 pa and can achieve U-Values as low as 1.4 W/m2K, meaning both doors will keep your home at optimum temperatures while ensuring your energy costs are reduced.


It is clear that both bifold and sliding doors offer a range of benefits for the home, but the choice generally boils down to the needs of the property, personal preference on features as well as the amount of space available.
