Why Aluminium is the best frame material

With cheaper UPVC options available, some customers may wonder if aluminium frames are worth the cost.

Aluminium is the strongest and most hardwearing material for window frames. The frames are resistant to flexing and twisting with little maintenance required.

One of the main selling features for aluminium frames is the slim lines they create.

The desirability of bifold doors is to create a seamless view outside. With the strength of aluminium, glazing framework is kept to a minimum, allowing more glass in each panel.


Aluminium bifold doors personalised to your project


Aluminium bifold doors installation process

Every build or conversion requires different features. Our made to order aluminium bi folding doors offer a wide range of personalisation choices.

You can select from three different glazing options that each benefit from a variety of thermal U values.

Door opening can be inward or outward depending on the requirement of the customer. If required, an outside handle or key locking feature can also be included.

A broad range of colour options are available from the standard white to the more contemporary black. On request, we can also produce bespoke colour to suit your project.

The delivery of your bifold doors includes complete installation guidance.

It is essential to check the delivery carefully as you unpack to make sure there are no missing parts.

Before starting the installation process, we recommend that a site survey is completed. The survey should check for any defects or damage to the structural opening.

The wall construction should be inspected to make sure the load capacity can be supported. The abrasiveness of the edges needs to be observed to plan for adhesive sealing systems.

Once the install is complete, it is important that you clearly explain to the customer how the system should be operated.

The end-user of the bifold door system needs to clearly understand the function of the supplied product and how to operate the doors safely.

The customer must store the instructions safely and ensure they are passed on to a new owner if the property is sold. To ensure longevity of the aluminium bifold doors, the customer must be aware of the care and maintenance required.


Care and maintenance

The care and maintenance required for Bifold doors is minimal. 

The most important care requirement is that the top and bottom tracks are kept clear from any debris. Objects or dirt on the tracks can stop the function of the folding door operating correctly. 

The locking mechanisms should be checked at regular intervals to make sure that they are clean. Every year the moving parts should have a lubricant applied, such as machine oil.

Aluminium Bifold Doors – A Beginners Guide

When it comes to glazed entryways, there is one modern solution leading the pack: bifold doors. Their flexibility helps homeowners maximise their space, offering an uninterrupted eye-line and a smooth flow of natural light through a property. However, no matter how popular an installation is, a large change to your home is always worth looking into before you invest. With that in mind, here’s a beginners’ guide to bi folding doors.

a beginners guide to bifold doors

The main difference between bi fold doors and their alternatives, such as patio doors, is the hinge system between the panels. This allows each section to fold away neatly to the side of the entryway. The design, often called a concertina system, enables the whole wall to disappear, expanding the living area and seamlessly connecting indoors and out.

While sliding patio doors, like large windows, only open one panel at a time, bifolds completely open the space. Whether you want to show off a beautiful garden vista, or simply expand a stuffy back room, bifolds offer a degree of versatility that other systems simply can’t.

Although, as mentioned, bi fold doors lead the market in glazed door solutions, they’re not a new phenomenon. In fact, scientists found evidence of folding doors in the ruins of the Roman city of Pompeii! So, what makes them such an enduring favourite across countries, cultures, and centuries? The main factor is their flexibility and power to open up a space.

On top of these benefits, 21st-century design innovations add some updates to the bifold system that push it right to the forefront of domestic design. When closed, bifold doors become extremely secure and durable. Their frames provide a network of defences against invaders, as does their frame-mounted track. Modern bifold doors feature complex multipin lock systems, and materials to resist weather and intruders alike. When shopping for bifolds, or any door, look out for the Secured By Design accreditation, an initiative developed in conjunction with the police to ensure your entryways are as safe as can be.

The smooth, measured action of bifold doors also keeps kids safer from slams and caught hands. The wind can’t blow a bifold shut it the way it would a standard door, providing the owners with a greater peace of mind. Bifold doors tread the design-line between door and window, introducing complexity without going too far. Bifolds can still be installed within a day, unlike more complex glazing projects like structural glass or conservatories.

Designers and manufacturers build modern bi fold doors from either timber or aluminium. With timber, buyers get a traditional look, which might fit best in a period house with exposed wooden beams. When stained and varnished, wooden frames bring a classically rustic appeal. However, like older houses, timber grows vulnerable to weathering and damage with age. Wood warps, swells, and cracks over time. This means that wooden frames need a repaint at least once every couple of years. The strength varies between softwoods and hardwoods, but hardwoods bring a heftier price tag.

The other, more durable material used in bifold door construction is aluminium. Pound for pound, aluminium is far stronger than wood, allowing doors with slimmer, less intrusive frames to offer more impressive views. Frame size even comes into play when the doors are folded. Bulky panels create a large unsightly stack beside the doorway, but slimmer frames are unobtrusive.

Aluminium bifold doors also require less maintenance than their wooden counterparts. As a rust-proof metal with weather-resistant coating, aluminium ensures a clean, unblemished look even through the worst of British weather. Rather than a full repaint, a simple wipe-down with a cloth will do the job. The most common colour for aluminium bifolds is a timeless anthracite grey. This matte look stands apart from the plasticky whites and blacks of uPVC for a minimalist, modern aesthetic.

Your bifold requirements vary dramatically depending on the size and position of the property’s opening. One thing to consider is the number of panes, or leaves, you want for your bifold door. Installing an odd number of leaves allows for one panel to be opened by the handle without using the rest of the mechanism. This odd door, sometimes called a traffic door, becomes a usable opening without unfolding the rest of your bifold. A traffic door makes perfect sense when popping into the back garden in the colder months. It provides quick access to the garden without venting a whole room’s worth of warmth.

On the topic of warmth, it’s also worth considering whether to opt for double glazing or triple glazing. While triple glazing increases the upfront cost, it may well pay for itself in heating savings. On top of that, triple glazing, and bifold doors in general, increase property value with a modern entryway upgrade.

By design, bifold doors display their advantages over other glazed doors with smooth efficiency. With extra protective frames and more flexibility than alternatives like French windows and sliding patio doors, bifolds offer clarity and security to well-designed residences. Their innovations in durability and space make them a staple of domestic design from the distant past to the cutting edge of the future.
