Our Range of Prefinished Bifold Internal Doors

Direct Doors is a trusted pre-finished folding door supplier, backed by multiple industry awards. With the UK’s largest selection of interior doors, we make it easy to choose the ideal product for your style and budget. 

Our folding doors create a seamless transition between living areas, offering a space-saving solution without compromising on style. Each door uses the highest quality veneer over a specialised core to ensure long-term functionality and sustainable timber use.  

Built to withstand daily wear, these internal folding doors rely on premium core constructions to stand the test of time:

• Solid core: These heavy-duty doors offer the best sound insulation and a sturdy, high-end feel for busy family areas.

• Semi-solid core: Offers a smart middle ground, delivering reliable strength and weight at a more accessible price point.

• Hollow core: Our lightest and most affordable option, perfect for dividing rooms when budget is the main priority.

Here’s what to expect from our range of prefinished internal folding doors.

Diverse Folding Door Configurations

Reclaim your living space with new internal bifold doors that eliminate the wide arc of a traditional door, creating a clean, open-plan feel. Our selection of versatile folding door configurations allows you to choose exactly where the folded panels sit when opened:

• 2+0 Bi-fold door: A standard two-panel pair that folds neatly to one side, perfect for smaller openings.

• 2+1 Internal folding door: Features a single "daily access" door alongside a folding pair for quick movement between rooms.

• 2+2 Internal bifolding door: A symmetrical four-panel layout where two doors fold to each side of the frame.

• 3+0 prefinished folding door: Three panels that all glide and sit to one side for a wide, clear opening.

• 3+1 Prefinished folding door: Combines a three-door folding set with a separate lead door for convenient daily use.

• 3+2 Internal folding door: Our largest five-panel setup, offering multiple ways to partially or fully open your open-plan living spaces.

For a practical setup that keeps the floor space completely clear, our top-hung systems are the ideal fix. By eliminating the need for a floor-level track, these low-maintenance doors sit flush with the floor for a cleaner, safer threshold as you enter.

Versatile Folding Door Faces

We source FSC-registered sustainable timber wherever possible and apply a high-quality prefinished surface to meet strict industry thickness standards. These real wood veneers celebrate a unique, distinctive grain, providing a striking contrast and organic feel once hung:

• Oak veneer: A timeless choice that brings natural warmth and a rugged, dependable finish to any traditional or modern room.

• Walnut veneer: Offers a richer, darker tone for homeowners wanting to add a sophisticated, high-end edge to their interior aesthetics.

Our factory paint finishes provide a flawlessly smooth surface right out of the box. These doors arrive ready to hang for a crisp, uniform look that cuts out the mess and hassle of DIY painting.

Find the perfect match to tie your entire decor together with these folding door colours:

• White: Brightens up darker hallways and creates a clean, airy backdrop that never goes out of style.

• Grey: A versatile, modern neutral tone that adds subtle depth without overwhelming your furniture or wall colours.

• Light grey: Brings a softer, contemporary touch to the interior, keeping your living areas feeling bright and spacious.

Types of Prefinished Bifold Doors 

Whether you’re trapping heat in a draughty room or creating an open-plan living space, every internal bifold door in our collection serves a specific purpose. Significantly improve your home's thermal efficiency and flow by simply matching the door type to your floor plan:

• Flush bifold doors: Feature a smooth, flat surface that offers a clean, minimalist look for modern interiors. 

• Panelled bifold doors: Built with recessed or raised solid panels, adding traditional character and a sense of depth to any structural opening.

• Glazed bifold doors: Large glass panels let natural light into the house, keeping separate areas connected even when the doors are closed.

Glazing Options 

Beyond dividing rooms, our glass internal bifold doors guide the flow of light and sightlines between areas in your home. Explore a range of glazed bi-fold door options that maintain an open-plan feel and secure your quiet spaces:

• Clear glass: Maximises visibility and light flow, keeping rooms feeling large and interconnected.

• Bevelled glass doors: Feature slanted edges that catch and refract light, adding subtle decorative depth to the glass surface.

• Frosted glazing: Perfect for areas requiring total privacy, as frosted glass completely obscures the view.

• Designer bi-fold doors: Unique patterns and styles that serve as a focal point, allowing you to inject personal character into your doorway.

Internal Folding Door FAQs 

Find answers to common questions about our pre-finished folding doors for sale.

What’s the difference between pre-finished & fully finished doors?

Both arrive ready to hang once you've attached the hinges and other essential door furniture, so you can skip the mess of sanding and staining:

• Fully finished bi-fold doors are supplied complete with a professional factory-applied coat of paint or stain.

• Prefinished bi-fold doors offer the same out-of-the-box convenience but are often even quicker to hang and finish.

Choosing either of these provides a much faster alternative to primed folding doors, which still require a final topcoat to properly protect the wood.

What are the space requirements for internal bifold doors?

Whether you are working with limited space or a sprawling open-plan layout, our door sizes are designed to fit your home's footprint exactly. 

The overall space requirements for our internal bifold doors range from compact single-room dividers to full-width structural partitions: 

• Small bi-fold doors (1981 mm x 686 mm - 2084 mm x 1597 mm): A smart, space-saving solution for utility rooms or en-suites where swinging a traditional door open just won't fit.

• Medium bi-fold doors (2084 mm x 1749 mm - 2084mm x 2592 mm): Perfect for opening up smaller spaces like dining rooms, giving you the choice between a cosy retreat and a wider flow.

• Large bi-fold doors (2084 mm x 2825 mm - 2084 mm x 3514 mm): Designed to bridge two main living areas, creating a seamless transition that pulls light deep into the house.

• Extra-large bi-fold doors (2084 mm x 3894 mm - 2084 mm x 4274 mm): Functioning as movable walls rather than simple doors, these make a dramatic architectural statement that completely reshapes your floor plan.

Note: The doors that are 2040 mm in height are 40 mm thick.
