Bi-Fold Doors

Flood your home with natural light

Bi-Fold Doors

Maximize Your Natural Light

Bi-fold doors, like sliding patio doors, will help to maximize the natural light which comes into your home, whether they are open or closed. Getting natural light in can really lift a dark room and turn it into a space where you want to spend more time.

Garden Access

Bi-fold doors are great for opening up access to your garden space. This allows you to enjoy your outdoor space with the comfort of being indoors at the same time. Bi-fold doors will make the best use of the room and the patio or lawn at the same time.

Better Security

Bi-fold doors feature a locking system which is spread over multiple points along the sliding track. This offers a great level of security when compared to other types of glass door, which usually only have a single locking point.

Low maintenance

Bi-fold doors don’t require as much maintenance as you might think. Usually they just need a regular cleaning with detergent, like most other windows or glass doors. They may be easier to clean than other complicated windows with multiple window panes built into a single frame.


EcoThermasol Bi-fold doors offer more flexibility than other types of door. A great set of Bi-fold doors allow you to fully open the wall or open the doors to any width within the frame, and you can customise the doors so that the leaves split in different places. When you compare these to a normal door which can open at only one width, or a sliding door which can open to a maximum width of half the length of the whole window, the flexibility offered by Bi-fold doors is far superior.


Unlike sliding patio doors, Bi-fold doors take up very little space when open. That’s because they concertina back on themselves, rather than sliding behind another window. This offers the benefit of opening up your wall completely. A sliding patio door will always require another door to slide behind, so even if your wall space is too small for patio doors, Bi-fold doors are still an option. You can even have them stack outside if you don’t have space in the room.

Aesthetically Pleasing

Having a wide set of Bi-fold doors not only brings in plenty of natural light (thus making a room more aesthetically pleasing on the inside), but it also makes your home look slick and modern outside too. You can choose from a range of designs and styles to perfectly match the rest of your home, whether you want them to blend into the building materials or stand out for a greater impact.

open up the outside

A popular feature Bi-fold doors are their seamless ability to open up rooms to the outside once installed. In second’s large Bi-fold doors can be easily folded back to open up any property, making them perfect additions to any extension. Bi-fold doors can go up great sizes of 1200mm x 3000mm allowing a huge amount of light into a property.

Highly thermal efficient

Historically aluminium products have been known for having poor thermal values. This is simply not the case with modern day aluminium products, in particular the aluminium Bi-fold door. Using standard glazing a 1.6 – 1.7 U-Value can be attained, which is a great standard of thermal efficiency, but if required triple glazing or a higher standard of double glazing can be used to get the U-Value down to 1.4.

Adds value to a property

It is very often that our clients will add aluminium Bi-fold doors, or other aluminium products to their property’s to add value to them. They do it ever so well. Having a large opening at the rear of a property that lets a vast amount of light in and can be fully opened is a fantastic addition, and really makes a property stand out. Aluminium Bi-fold doors are becoming increasingly popular additions to renovations and new builds.

Wide range of colour choices

One of the most fantastic features of the aluminium Bi-fold door is the option to have almost any colour imaginable powder coated onto the aluminium. This has appealed to a great amount of our clients, as being able to choose the colour of your EcoThermasol Bi-fold doors from a swatch, much like you would the colour of your wallpaper, makes it far easier to create the perfect home or project. Not only can you choose your perfect colour, but you have the peace of mind in the colour lasting over time, as the finish is guaranteed for 25 years from many powder coaters.

High Security

The aluminium Bi-fold door does not only look great, it is also incredibly secure. Often with multi point locks as standard and secured up to WK1. It is also very easy to upgrade the security on an aluminium Bi-fold door, and we often have clients asking us to add additional security features to give them further peace of mind. The aluminium itself is incredibly strong itself and creates a very secure base, without taking any of the high quality hardware into consideration. The increase in engineering that goes behind designing and creating modern day aluminium Bi-fold doors will only increase the security features evermore, and it is certainly a product to keep an eye on.
