Bifold doors, sometimes called folding doors, have become increasingly popular in homes over the past decade.

As their name suggests, bifold doors fold in half and stack neatly when opened, making them space-saving and stylish additions to any room.

If you’re considering installing bifold doors in your home, this comprehensive guide covers everything you need to know, from costs and materials to types, pros and cons.

Bifold doors consist of door panels that are connected by hinges that allow them to fold up accordion-style.

When open, the doors stack neatly to one or both sides of the doorway.

Typically, bifold doors are used for closets, pantries, laundry rooms and between rooms. They can be used in place of traditional swinging doors to save space or create an open-concept feel.

The number of door panels can vary, with two, four, six and eight panel configurations being most common.

Panels are usually of equal width and fit together when folded. The hinges, rollers and tracks allow the doors to slide and fold smoothly.

Bifold doors can be made from various materials, with some options for example:

  • Wood: Natural woods like oak, maple and cherry add warmth and elegance. Wood can be painted or stained for customized looks.
  • Vinyl: Affordable and low-maintenance, vinyl bifold doors have a modern, sleek appearance. Popular vinyl colours are white, beige and brown.
  • Aluminium: Lightweight aluminium offers a contemporary look and is easy to maintain. Anodized aluminium comes in shades like champagne, bronze and black.
  • Fiberglass: For a wood-like look with added durability, fiberglass bifold doors are a great choice. They require less maintenance than real wood.
  • Wrought iron: Intricate hand-forged iron designs make a dramatic style statement. Wrought iron is durable and perfect for a Tuscan aesthetic.

Consider factors like your budget, room decor and desired functionality before choosing.

There are a few main types to consider:

Interior Bifold doors

Interior bifold doors are suited for closets, pantries, laundry rooms and dividing rooms. They fold compactly out of the way and don’t require much clearance for operation. Interior bifold doors may be simple panel or mirror/glass styles.

Exterior Bifold Doors

Exterior bifold doors open up rooms to the outdoors. They’re ideal for patios, decks, porches and capturing panoramic views, whereas Exterior bifold doors need to be weatherproof and made of durable materials like aluminium or vinyl.

Room Dividers

They can make great room dividers. They can partition large spaces into multiple smaller areas or temporarily cordon off parts of an open floor plan. Tracks and hardware allow the doors to fold and stack out of sight.

Pocket Bifold Doors

Pocket bifold doors slide completely into recesses in the wall framing when opened. This saves even more space compared to regular bifold doors while maintaining an uninterrupted look. Installation is more complex though.

One of the benefits of bifold doors is they come in a wide range of standard sizes to fit any space perfectly. So the most common interior door sizes are:

  • 24-inch x 80-inch
  • 28-inch x 80-inch
  • 30-inch x 80-inch
  • 32-inch x 80-inch
  • 36-inch x 80-inch

Exterior bifold door sizes are often larger to span wider openings. Some standard widths are 4 feet, 6 feet, 8 feet, 10 feet and 12 feet. Heights usually range from 6.5 feet up to 8 feet.

Custom sizing is also an option if you have an unusually sized space.

When measuring for bifold doors, be sure to account for proper clearance. They need extra room to fold and stack on each side. Your contractor can help determine ideal bifold door sizes for your project.

On average, bifold doors cost £450 to £1,100 installed. Here’s a breakdown of what impacts the overall project cost:

  • Door material: Vinyl is the most affordable at £110-£220 per door. Wood costs £220-£600 per door, while fiberglass and aluminium fall in the mid-range. Wrought iron is high-end at £500-£1,100 per door.
  • Number of panels: More panels equals higher cost. For example, two-panel doors will be cheaper than eight-panel versions.
  • Door size: Larger bifold doors naturally cost more than smaller sizes. Custom oversized doors add expense as well.
  • Hardware: Pricier hardware with stainless steel, soft-close hinges and antimicrobial coatings obviously increases the total price.
  • Installation: Complexity of install and contractor fees for labour will impact cost. Expect to pay £150-£450 for installation.
  • Special features: Added details like clad frames, glass inserts or custom designs can raise the budget.

Bifold door costs ultimately come down to the materials used, special features and contractor rates in your area.
