Our Complete Bi-fold Doors Buying Guide

Lifestyle

If you’re thinking of installing new external glass doors into their home, your first decision will often come down to whether or not your new view is securely protected by a set of sliding or bi-folding doors.

To help with making your decision, we always recommend heading down to one of our showrooms and speaking with our experts. However, in the meantime, we’ve created this in-depth bi-fold door buying guide to cover everything you need to know.

WHAT ARE BI-FOLD DOORS?

Although bi-fold doors and sliding doors share numerous similarities, it should come as no surprise that they’re mainly differentiated by the way they open. As the names imply, sliding doors slide, while bi-fold doors fold.

And by fold, we mean that a set of bi-folding doors has the ability to stack each separate pane on top of each other in an accordion-like manner, allowing you to swing the door to one side once fully folded to provide you with an unbroken view and exit to the outdoors.

HOW DO BI-FOLD DOORS WORK?

While simple in principle, there’s more that goes into enabling this type of door to fold in on each other than you might think.

First and foremost, the frame of each door pane is joined by a set of durable hinges, designed to take the weight of either adjoining frame once it’s removed from its holdings.

But that’s not the only weight-distributing feature. Like doors that slide, bi-folds are still connected by a set of runners, ensuring they’re supported properly when fully open.

WHAT MATERIALS ARE BI-FOLD DOORS MADE FROM?

As with any type of bespoke window or door, the frames of bi-folding doors can be constructed using a variety of materials that cater to different aesthetics. The following are the most common:

  • Aluminium
  • Timber
  • PVC
  • Composite

All of these have their pros and cons as construction materials. However, it’s important to note that, here at Express, we exclusively produce our frames from aluminium in order to give our customers a product that’s long-lasting and flexible when being styled.

ALUMINIUM

In most cases, Aluminium is considered to be one of the best materials for constructing bi-folding doors, mainly due to its versatility and strength. Aluminium bi-folding doors allow for beautiful, slender frames that widen your window space, and are durable enough to support large panes of glass that provide truly panoramic views.

TIMBER
With its classic, rustic feel, it’s clear why timber is another favourite for those interested in getting bi-folds. And if the wood is used alongside aluminium, it can help to reinforce the strength of the doors themselves, meaning they will ultimately last longer.

However, timber tends to require more maintenance than other materials to avoid warping, but if properly made by a specialist company, timber bi-folds can provide a stylish alternative to aluminium.

PVC
PVC might be the cheapest material option, but it’s also perhaps the least practical. PVC often expands and contracts as a result of temperature change, making opening and closing doors more difficult, and it may become a security issue if improperly closed.

PVC is also much weaker than other materials and is less able to hold large panes of glass as a result.

COMPOSITE
For something that seamlessly combines a traditional appearance with the practicality and performance of aluminium, composite bi-folds are sometimes a popular choice.

Offering a traditional timber-clad finish with all the benefits of an aluminium door, composite is a strong candidate for period properties where homeowners don’t want a modern aluminium aesthetic.

 

BI-FOLD DOOR GLAZING OPTIONS

One of the biggest parts of making any set of bi-folds is the glass that’s used. Making your home look that much lighter, warmer, and inviting, it’s no wonder why so many people take their glazing so seriously.

There is a large range of options available to homeowners when it comes to door glazing, but determining what type is right for your home depends entirely on the purpose you envision your bi-fold doors performing.

To give you an idea of the type of glazing available, here are a few of the glazing options you can choose from:

  • SGG Planitherm Total – a higher performance, thermally insulating glazing.
  • Solar control glass – specially coated glass that reduces heat absorption.
  • Self-cleaning glass – specialised glass that minimises the build-up of dirt.

Naturally, there is much more to each glazing type, so be sure to get in touch with our experts to find out more about each option

WHAT ARE THE PROS AND CONS OF BI-FOLD DOORS?

As you might expect, there are plenty of benefits of bi-fold doors. Not only do they provide a real wow factor to your home, but they can provide a huge source of natural light throughout the year.

BENEFITS OF BI-FOLD DOORS

The following are just some of the major benefits associated with bi-folds:

  • Security – our bi-folding doors boast a multi-point locking system and shatterproof glass for enhanced security measures.
  • Light – big panes of glass mean plenty of light can be welcomed into your home all year round.
  • Air circulation – fully opening your bi-folds allows you to quickly freshen up the roof and welcome in clean air.
  • Easy maintenance – thanks to their aluminium construction and the powder-coat paint we use, our folding doors are exceptionally dirt resistant.
  • Eco-friendly properties – unlike traditional paint types and PVC, aluminium powder-coat doors create minimal waste during construction.
  • Luxury views – with reduced frame sizes and huge panes, you get fantastically wide views over your garden.

DRAWBACKS OF BI-FOLDING DOORS

However, these great benefits also come with some drawbacks, of which the main ones include:

More framesalthough the frames of folding doors are slim, the nature of their construction does mean that they include more frames than sliding doors, breaking up your view to a larger degree.

Spacedepending on how your new folding doors need to be installed, they may very well take up more space than desired once fully open, making them less than ideal for small homes.

For those still unsure how to open bi-fold doors, the process is very simple. Once unlocked, you only need to gently lift the door up, allowing you to effortlessly fold the door panes in on each other. Once folded, you need only swing the door to one side so it’s out of the way
