Ultra Slim Bifold Doors
UK’s Leading Manufacturer & Installer of Glass Bifold Doors
Here at FinlineDoors we have successfully been manufacturing and installing aluminium bifold doors for over a decade. Our experts not only specialise in the manufacturing and installation processes but also excel with regards to design and ergonomics which is what we believe gives us the edge over many of our competitors. Aluminium bi-fold doors have become increasingly popular amongst home owners as their true benefit to ones living space has been recognised.
Before the emergence of bi folding doors in the UK the majority of houses were fitted with basic double glazing sliding or opening doors. When aluminium bi-folding doors were introduced it was clear to see their far greater superiority with regards to design, energy efficiency, appearance and maintenance. One of the key differences, or improvements if you like, between the traditional sliding patio doors and these new alternative bifolding doors was the mechanism by which they open. Unlike the older sliding doors, bi-fold doors can be folded back just a few inches in the opening therefore allowing more of the environment to be experienced and the space within the living space is used to its maximum potential. Whereas a traditional patio door will only open up say half of the available opening a bi-fold door will open up almost all of it, bar a few inches. This makes a significant difference with regards to lighting and space properties.

Why Choose Ultra Slim Bi-folding Doors?
These express bi-fold doors possess the key feature which is the ability to fully retract and therefore offer various opening configurations. For example you can open aluminium bi-folding doors into or out of a room, fold them to the left, right or even round a corner. The sheer versatility and effectiveness of these bifolding doors are one of the reasons why they are so popular. One of the most common uses of aluminium bifolding doors is to separate the space between the living area and the garden. Having bi-folding doors in this particular scenario is so effective because it maximises the light and space properties for that particular living space. Alternatively many people chose to have internal bi-fold doors which usually separate one room from another. Bi fold interior systems are most commonly used between the kitchen and the conservatory as a space divider and one of its main benefits in this system is its ability to retain heat. Internal bi fold doors are also used in this scenario to once again maximise the space available and also create more natural light options. For these reasons bifold interior doors have become considerably more popular over the past few years.
