Author: John Collins - Managing Director

When choosing a new patio door for your home, it can be difficult to know which options are available when it comes to the materials. Choosing the right bifold door material can be difficult. When installing any external door, you need to consider the location of your door, the elements it may face, the amount of insulation you require and much more to make sure your new bifold patio doors are right for your home. In this guide, you will find an overview of the most popular bifold materials as well as comparisons.

Popular bifold door materials

Wooden bifold doors

Wooden bifold doors combine stunning natural aesthetics with practicality and durability. Most internal bifold doors are made from wood due to its excellent sound absorption and reasonable price. Wood is also a popular external bifold door material, although extra consideration is needed.

An internal or external folding door can be made from many different kinds of wood, the most common being hardwoods like oak due to their durability, lifespan and insulating properties.

Benefits of wooden bifold doors

  • Natural insulation –– timber bifolds uses air pockets within the cellular structure of the wood to create a natural barrier between the heat and cold
  • Durability –– Vufold offers up to 10 years guarantee on external and 15 years for internal timber bifold doors
  • Customisable style –– an external wooden bifolding door will suit modern and traditional homes and can be stained, varnished or painted almost any colour. You may want the wood of your doors to match the wood in your kitchen or prefer white doors to match other doors and windows in your home
  • Excellent sound absorption –– wood also absorbs sound so can create quieter rooms or external bifold doors can dull the sound from outside
  • Environmentally friendly –– the process of manufacturing timber requires fewer fossil fuels than other materials

Types of wood available

A wooden bifold door will most likely be made from one of the following materials:

  • Hardwoods such as oak
  • Softwoods such as pine


Hardwoods are an excellent choice for external bifold doors due to their excellent insulation properties, durability and lifespan. If treated and maintained properly, hardwoods are resistant to mould and fungi meaning they are an excellent choice for external bifold doors.

Main features of oak:

Oak is the most popular types of hardwood for bifold doors. The main features of oak are:

  • Distinctive light beige
  • Medium to coarse texture but can be veneered for a smooth feel
  • Incredibly durable
  • Unique grain pattern
  • Excellent thermal efficiency


Softwoods such as pine are often used in cheaper internal bifold doors. Pine is not an ideal material for external bifold doors due to its tendency to warp. The price of softwood bifolds may be tempting but there are several drawbacks to softwoods which you should take into consideration. See our comparison table below.

Main features of pine:

Pine is probably the most popular type of cheap softwood material. The main features of pine are:

  • Pale yellow appearance
  • Cheap to buy
  • Good thermal properties

Are aluminium bifold doors better than uPVC?

Aluminium and uPVC are both popular materials but for very different reasons. Aluminium provides longevity, durability and style while uPVC is popular for its low price. In the table below, you will find the key differences between aluminium and uPVC.

Aluminium vs uPVC bifold doors

  Aluminium uPVC
  • Has the longest expected lifespan of any material
  • 15 year guarantee
  • 20 – 30 years expected lifespan
  • 10-year guarantee
  • The cheaper the door the shorter the lifespan
  • Powder coated to protect from corrosion
  • Resistant to heat and light damage
  • Resistant to expansion/warping
  • Not as durable
  • Prone to warping which can create draughts and affect operation
  • 2.5 times more expansion than aluminium*
  • Wash with soapy water every six months
  • Less likely to show dirt than uPVC
  • Wash with soapy water every six months
  • If expansion has occurred, adjustments may need to be made
  • Can be recycled
  • Considered carbon neutral
  • Faced a lot of environmental controversies
  • The incineration of PVC releases Dioxins - highly toxic chemicals known as persistent environmental pollutants (POPs). Dioxins can remain in the environment for many years.**
Finish and styles
  • Aluminium is known to be a stylish and versatile material
  • Aluminium doors can be powder coated in almost any RAL colour
  • Powder coating can increase durability and resistances
  • Does not provide the same style as aluminium
  • Can often look cheap
  • Wide variety of colours available
Initial costs
  • Higher upfront costs
  • considered an investment
  • Lower upfront costs
  • Shorter lifespan
Long term costs

Low maintenance and high durability mean low long term costs

More likely to have to pay repair/maintenance costs which can add up over the years

Choosing the right glazing for your bifold doors


Glass is a key component to a bifold door. It’s probably the main attribute that makes people desire a bifold door. Glass takes up the most space on a bifold door, providing the natural light and stunning views.

You want to ensure your bifold glass is both thermally efficient and secure. To do this, you need to look at the type of glass and glazing.

Type of glass

When you purchase a bifold, it will likely be made from the following types of glass:

  • Tempered safety glass –– created by rapidly heating and cool glass to increase strength
  • Laminated glass –– created by sandwiching vinyl between two pieces of glass to hold the glass together

Tempered safety glass vs laminated glass

  Tempered safety glass Laminated glass
Strength 5X stronger than standard glass
  • Same strength as standard glass
  • Vinyl holds the glass together when shattered
  • Shatters when broken
  • Can alert the neighbours
  • Holds together when shattered
  • May take several hits to break which can alert neighbours
Price Unlikely to increase costs May cost extra


Glazing is incredibly important on a bifold door. Because glass takes up the most space on a bifold door, it’s the material that is most likely to let energy escape. The glass type and the thickness of the glazing units will impact on how energy efficient the bifold door is.

It’s very unlikely you can purchase a single-glazed external bifold door. Single glazing is old technology and the least thermally efficient type of glazing. In this section, we will focus on double and triple glazing.

Double glazing vs triple glazing

Double glazing is made from two panes of glass that creates a cavity which is often filled with an innate gas (known as a thermal break). This gas-filled cavity creates a barrier between the inside and outside providing insulation.

Triple glazing uses the same technique except it uses three panes of glass to create two separate thermal breaks for even better insulation.

Benefits of triple glazing

  • Excellent sound insulation
  • Produces low U-value
  • Extremely energy efficient
  • Incredibly long-lasting

Both double and triple glazing provide excellent thermal efficiency. Vufolds bifold doors are either double or triple glazing.

The costs of bifold door materials: A comparison

The average costs of bifold doors can vary depending on the size, material and whether you’re looking to fit them internally or externally. The cost of the doors you choose should be carefully considered to ensure that your budget will cover the right folding doors for your home.

Door configuration and size guide

Bifold doors are configured in pairs. The smallest bifold patio door you can get has two doors. The largest is six doors, unless you are looking for a bespoke door, which can be bigger.

If space is available, Vufold recommends three doors as a minimum so one panel can act as a traffic door, meaning you don't have to open the entire bifold every time you want to get through.

The table below will show the aperture size and the number of doors required depending on the material.

Aperture size Aluminium Wood Composite uPVC
Up - 2 metres 2 doors 3 doors 3 doors 3 doors
2 - 3.6 metres 3 or 4 doors 3, 4 or 5 doors 3 or 4 doors 3, 4 or 5 doors
3.7 - 5 metres 4 or 5 doors 5 or 6 doors 5 or 6 doors 5 or 6 doors
