Bifold doors are a familiar sight these days — and it’s not hard to see why.

Not only are bifold doors the perfect way to pull in plenty of natural light but they also create a visual and physical link to the outdoor spaces beyond. Incorporating bifold doors into both period renovations and modern extensions is one of the simplest ways to bring a space to life — plus it can add to a sense of space in smaller homes too.

Maximising glazing in a project is widely accepted to be every homeowners number one desire  — plus increasing natural light has been proven to have a positive effect on wellbeing.

However, the huge range of materials, sizes and styles on offer can make difficult to know which bifold doors are right for your home. So, how do you choose?

Arming yourself with knowledge and investigating which option offers the best in terms of operating systems, material and aesthetics will help you pick the best for your budget.

Choosing the Best Material for Your Bifold Doors

The material of your bifold doors will play a big role in both the overall look of the room, as well as the practical side of living with them. Doing a little research into maintenance, installation and, of course, cost is essential.

Try to get at last three quotes and compare quality of the material (especially with aluminium or timber) and ease of installation, as well as how the lead-in times will fit into your project’s schedule. Asking trusted sources for recommendations is also a great idea.

Aluminium bifold doors are versatile because of their strong but lightweight composition and are a great choice for more contemporary-style homes as they can come in a very slim frame. 

Benefits include:

  • Slimmer sightlines

  • Easy to maintain

  • A lifetime-lasting powder-coated finish

  • Can be made wider than timber doors (meaning fewer doors are required within the frame)

  • Finish options for frames include an array of RAL colours

A beautiful and classic option for those creating a traditional-style home or looking to install in a period property, wooden doors come in various finishes. Engineered timbers are ideal as they have more dimensional stability than solid timber doors.

Softwood products are cheaper than hardwood, but some lower-end models can still be prone to warping over time when exposed to heat and moisture, meaning they will stick in their frames or won’t close.

They will require regular painting or varnishing to maintain their appearance.

If you really can’t decide between the practically of aluminium and charm of timber bifolds, opt for a composite. It usually consists of an aluminium frame with a timber internal facing, offering the best of both worlds.

Always thought of as the cheap and cheerful option of windows and doors, PVCu (also written as uPVC) are low maintenance but don’t come with the slim sightlines and quality of finish as timber or aluminium.

Bifold Door Sizes

When designing how large you want your bifolds to be, you need to work out the size of the aperture and the tracks. If you’re getting someone to install the doors for you, they might come out and measure but a DIY enthusiast can normally fit them quite easily.

Panel weight is affected by the size and type of glazing used and hardware systems have maximum individual panel weight, width and height restrictions.

  • The minimum size of aluminium panels is advised to be a three panel set with a width of 600mm per panel but typically the panel widths would range from 800mm to 1200mm so 2400mm is a more accurate reflection of the smallest size opening for bifold doors to be installed

  • Standard aluminium panels standard can be double or triple glazed 1,000 x 2,800mm

  • Specialist wooden doors can go up to 4,000 x 1,100mm and hold up to 16 panels in one frame depending on manufacture and tolerance.

The current trend towards wide run of glazed panels lets in the most light, as well as providing uninterrupted views outside. So to avoid heavy looking profiles that restrict light, reduce the size of the panes and the views, opt for slimline frames. There are many options out there with sightlines as slim as 115mm for aluminium frames.

Which Operating System for Bifold Doors?

Two key terms you will come across when researching bifold doors are ‘top-hung’ and ‘bottom-rolling’; both refer to the way the weight of the doors are supported.

Look for systems that are specifically designed for bifold doors as they require hardware systems with a greater capability than sliding or hinged doors. Wheels that run in flat tracks give smooth operation when compared to grooved wheels on a raised track.

Pros:

  • Can conceal the bulk of the operating mechanisms in the frame head

  • Dirt and leaves are less likely to become lodged in the top track

Cons:

  • They require a sufficiently strong lintel or beam above the opening to take the weight of the doors

Bottom rolling

Pros:

  • Don’t pull down as much weight from the top of the frame

  • Easier to install

Cons:

  • Door motion can be affected by dirt and leaves getting stuck in the bottom track

Bifold Door Configurations

Once you’ve established the width of the opening, investigate widths of panes available. This will then determine the sort of configuration you can go with. Companies will offer their advice and can talk through the different configurations with you.

Keep to an odd number of panels so they can stack and create a complete opening. With bifold doors a masterdoor is a good idea to gain easy access without having to open up the entire door system.

The simplest and most obvious way of screening bifolds is to install full-length curtains, but this does not mean it is necessarily the best option. They prove unpopular as they block light coming through the glazing even when the curtains are open, distracting from the sleek look offered by bifolds.

Another option is to house vertical blinds in a unit on the wall or build them into the ceiling but can hinder access from inside to out.

Some glazed units come with built-in venetian blinds which sadly partially obscure the glass but others offer screens and shades that move horizontally and can be drawn from the door jamb when needed, moved aside for access and retracted when not in use. 

Internal Bifold Doors

Open plan spaces are all the range in modern renovation, conversion and self-build projects, but in recent years homeowners are becoming more design savvy when creating spaces designed specially for their lifestyles.

Including internal bifolding doors is an ideal way to lean into the open plan aesthetic without disputing a home too much. They offer a flexibility of being able to simple fold away the partition when guests are visiting, or parents want to keep an eye on the kids while cooking dinner, while also allowing rooms to be shut away when privacy or a sense of cosiness is desired.

Choosing options with a glazed panel takes this idea one step further, in that natural light can still flood the spaces, while the practical functionality if internal doors is observed.
