Internal Bifold


Wooden internal door sets are known for their rustic appearance and inviting aesthetic. However, they are also available in a range of style options and colours, so you are guaranteed to find the perfect option for your home. The following are the main benefits of wooden internal bifold doors:

  • You can choose between a range of styles and designs — wooden bifold doors are available in a range of styles, allowing you to find the perfect option for your home. For example – you may want to choose a steel-look, industrial bifolding door for a more modern feel. Our unfinished oak Finesse doors, on the other hand, can provide more of a traditional feel.

  • Durable and long-lasting — Vufold offers a 15-year guarantee on all interior bifold doors. Engineered wood offers excellent durability and reliability.

  • Environmentally friendly — wooden doors have a simpler manufacturing process compared to synthetic materials, meaning less carbon dioxide. This is ideal if you are conscious about your impact on the environment, and are looking for a greener material.

  • Increased light — using bifolds with glass as a room divider invites more sunlight into both rooms.

  • Sound absorption — wood naturally absorbs sound, which can help reduce noise levels.

While handles might be one of the last pieces of door hardware you consider for your bifold doors, they still play an important role in both the overall look of the doors and can have an impact on interior design too. Most internal folding door handles fall into four main categories:


  • Often used on the lead door

  • Common type of handle

  • Simple mechanism.


  • Used to pull bifold doors towards you in order to close them

  • Numerous designs but most of them are D-shaped

  • Folds flat against the door so the doors can concertina closely together to take less space.


  • Another common type of handle

  • Available with two types of latches:

  • Tubular mortice latch—similar to a lever handle, except you twist to retract the latch

  • Roller latches (ball catches)—simple pull or push to open and close the door


  • Used for wardrobes or pantries rather than proper bifold doors

  • Recessed flat or flush into the door

  • Also known as a flat handle

Bifold tracks hold and guide the bifold door rollers, allowing the panels/doors to open and close. They consist of two sections: the main track and the guide track.

When researching bifold tracks, you will encounter two key terms, both relating to where the bifold door’s main track is located:

  • Top-hung (located in the frame head)

  • Bottom-rolling (bottom threshold of the frame).

You may also see references to ‘trackless systems’. A trackless system has no base track running across the floor of your room and can only be used with top-hung bifolds.





Smooth operation—top weight means less force is required to move along the track

Low-maintenance—highly unlikely that debris will collect in the upper track, so less maintenance is required

Lower threshold—the guide track is based at the bottom, which has a slimmer profile than the upper main track

Requires slightly less support—bottom-rolling systems have their weight carried on the floor

Installation—fewer holes are needed in the guide track that is located in the frame head

Secure doors—doors cannot fall out of top-hung tracks


Installation—the main track of bifolds must be securely fastened over the full length of the door set—this requires drilling holes upwards, which can be awkward

Blockages—debris and small items can jam the main track at the lower part of the door set

Maintenance—to stop blockages, you will regularly need to clean the bottom track

Track dipping—if the main bottom track isn’t perfectly level, the track can dip. This can disrupt operation and cause the doors to fall out of the guide track

Higher threshold—bottom-rolling systems have a higher threshold at the bottom of the door step. This is a trip hazard and is much harder to install flush.

Frequently asked questions

What are the benefits of using internal bifold doors?

  • Space-saving: They require less floor space than standard doors because they fold rather than swing open.

  • Flexibility: They allow for flexible management of space, as they can be fully or partially opened or closed.

  • Aesthetic appeal: Available in various designs and finishes, they can enhance the interior decor of a home.

  • Increased natural light: When installed with glass panels, they allow for an abundance of natural light to flow between rooms.

Can internal bifold doors be customised?

Yes, many bespoke bifold door manufacturers offer custom sizes and finishes to fit specific openings and match interior design themes. Bespoke internal bifold door options may include different types of glass, panel configurations, and frame materials.

How much do internal bifold doors cost?

The cost can vary widely based on the material, size, and customization options. Generally, wooden doors tend to be more expensive than those made of uPVC but are often cheaper than aluminium options. Additional features like thermal insulation or specialised glass can also affect the price.

What maintenance do internal bifolds require?

Maintenance generally involves regular cleaning and periodic checks of the track system and hinges to ensure smooth operation. Lubricating the tracks and hinges can help prevent wear and tear.
