Which is better for your home, bifold or sliding doors?

Sliding Doors

Making the decision between aluminium bifold doors and aluminium sliding doors for your home can be a tough one. To decide which is best for your home, it is important to understand the benefits of each of them and assess which will meet your specific requirements.

Ultimately, both sets of doors hold the ability to create a seamless connection to the outdoors and flood your living space with natural light. Each also boast slim sightlines so they can offer uninterrupted views of the outdoors.

Ease of Access

When comparing bifold and sliding doors, it is worth considering how the doors open and operate. Both doors provide a complete wall of glass when closed, with bifold doors offering the option for this to be folded neatly away and sliding doors offering a wider glazed area.

Regarding accessibility, both doors offer a low threshold option that allows seamless access between the home and garden for everyone.

Sliding Doors


View of Outdoor Space

Aluminium bifold doors can be fully opened to allow an expansive view of the outdoors. Aluminium sliding doors do not offer this 100% opening, as the doors must slide back against each other so one pane is always visible. It is usually dependent on the homeowner’s choice and their needs as to whether they prefer a fully accessible space, or if they just want a wall of glass. With the UK weather not offering many days each year where these doors can be fully open, sliding doors may be a better option to provide light and views of the garden without the need to save room for the storage of bifold doors.

Both bifold and sliding doors have slim sightlines, so both designs provide an expansive view with minimal interruptions or obstructions. With sliding doors having large glass panels and sightlines of just 48mm, they are arguably the better option if a view of your garden through the window is especially important to you. On the other hand, bifold doors offer a more expansive view when open in comparison to sliding doors, so this is something to bear in mind when making a decision between the two.
