Aluminium Bifold Doors

beautiful bifold doors

Install aluminium bifold doors and on sunny days there is no better way to bring your garden into your house. Bifold doors will change the way you use your living space giving your house a light and open feeling.  A BiFold door on the back of your property will also give a contemporary feel to the older properties.

We have been installing aluminium bifold doors for over 24 years in Derbyshire, South Yorkshire & Nottinghamshire - Sheffield, Chesterfield, Derby, Nottingham.

Bifold doors that are available in the market place can be manufactured from a range of materials and they are sometimes referred to as concertina doors.  Glass in the doors is extremely heavy and UPVC does expand in the heat of a sunny day which makes them difficult to open and close, whilst wood will require maintenance on a regular basis.  Aluminium bifold doors have a thinner profile and are strong.  They are powder coated and are available in all colours - over 200 different RAL colours and you can choose to have a different colour inside to outside.

Bifold Door Components

bifold roller & trackDue to the weight of the panels which contain toughened double glazing (or triple glazing) we put 4 hinges on each leaf of the bifold door to ensure the panels do not drop. Other bifold companies often fit only 3 hinges and in some cases 2 hinges. Fitting extra hinges also gives added security to your bifold doors.

We use the manufacturers recommended rollers for the doors - other bifold companies often cut their costs by fitting cheaper components. The stainless steel rollers glide on the track making it an easy manual operation to open the doors, time after time.

So when comparing doors, make sure you are comparing like for like.  We have fitted bifold doors in commercial properties that are still in use over 20 years later, with no problems.


Heritage colours

If you live in a conservation area such as the Peak District we have a range of power coated heritage colours available and we are familiar with the constraints of working in national park areas. If you looking to conform to building regulations you've come to the right place. We can co-ordinate our installations with the local building inspectors to ensure you get your doors signed off at the end of the project.

U-Value of Bifold doors

We often find that building control has specified a low U Value - we can work with you to ensure you achieve this U Value.  U Value is the measurement that is used to determine the heat being lost from a window or door. There are lots of factors which affect the U Value of BiFold doors;

the type of glass, the thickness of the glass;

the space between the double glazing; triple glazing; and

the gas between the double glazing panels (Argon is normally used).

Combining these factors we can work with you or your architect to ensure that we have a cost effective outcome to meeting with these U Values.


Blinds in Bifold Doors

4 Panel Bifold doors SheffieldIf you want to have blinds in your bifold doors, that's not problem either.  The blinds are installed inside the sealed double glazed unit so it saves them getting damaged or dirty.  There are limited on the width of the blinds depending on whether you wish to raise and lower them or if you just wish to tilt.  We can retrospectively fit these if you already have a bifold door fitted in your home.  It will mean replacing the sealed unit.  Read more about blinds

Bifold Door Configurations

with more panels there are more choices of configuration

When deciding on the configuration of your bifold doors, you need to plan which way the doors will open. The doors can either all swing to one side (left or right), or split in the middle of an even number of panes. With an odd number of doors, you will need to plan which door is to be the lead door. If this entrance is the only entrance to your back garden, a lead door may be beneficial as it will act like a single door rather than having to open the bifold each time you wish to use it. The lead door will be hinged at the wall edge and act like a single door. This door will have the main handle and key. Our showroom contains a bifold door, please give us a call if you want to visit.




We have installed bifold doors in commercial properties as well as domestic

- so you can be assured that they will stand up to constant day to day usage.

The most popular BiFold door is made of 3 panels

but we have fitted doors up to 6 panels wide.
