What are bifold doors?

Bifold doors are multi-panel glazed doors that fold and slide to one side, creating a wide, openable space between your home and garden.

They’re ideal for kitchens, extensions, garden rooms and open-plan living areas.

Benefits of bifold doors

• Flood rooms with natural light
• Open fully for indoor–outdoor living
• Modern, slimline frames
• Multiple glazing options for insulation
• Strong multi-point locking
• Available in aluminium, uPVC, and timber

Bifold doors are often compared with sliding and French doors, but they offer the widest possible clear opening.

Signs you may need new bifold doors (or an upgrade)

• Doors sticking or catching on the track
• Draughts or visible gaps around the frame
• Cloudy or misted glazing
• Warped frames (common in older timber or uPVC)
• Outdated aesthetics reducing kerb appeal
• Your current doors don’t open fully or don’t suit open-plan living

If you’re upgrading from French or sliding doors, bifolds provide a wider opening and a cleaner, modern appearance.
