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 can 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 are available in the market place manufactured from a range of materials. 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. This 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 available in all colours - over 200 different RAL colours. You can choose to have a different colour inside to outside.

Bifold Door Components

Due to the weight we put 4 hinges on each leaf of the bifold door to ensure the panels do not drop - Other companies often fit only 3 hinges and in some cases 2 hinges.  We also use the manufacturers recommended rollers for the doors - others may fit cheap components. So when comparing doors, make sure you are comparing like for like.  We have fitted bifold doors in commercial properties that are still be used over 20 years on, with no problems. Fitting 4 hinges also gives added security to your bifold doors.

Heritage colours

If you live in a conservation area such as the Peak District we have a range of heritage colours available. 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. Fitting 4 hinges also gives added security to your doors

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 the meeting with these U Values.



A slim aluminium profile means less view is obscured by the frame.
