Stay warm in the winter and cool in the summer...

Designed to meet the demands of the UK climate, your bifold door from Instadoor will have been engineered to give superior weather performance. While aluminium bifolds invite natural light in and remove the barriers between inside and out, they also work to keep your home insulated all year round.

Our doors exceed British Building Regulations for optimum thermal efficiency as they boast a certified U-Value of 1.32, using some of the most sophisticated weather-tight seals to ensure the elements stay out. In real terms, this means energy bills will be reduced and your rooms will be usable all year round.


Low Maintenance

Enjoy the view and space created with bi-fold doors, without the worry of time consuming and complicated maintenance. The very nature of bi-folding doors demands precision design and engineering, making timber and uPVC inferior materials for maintaining alignment over the lifetime of the product.

With high grade aluminium, however, expanding and contracting is minimal, so it is guaranteed to offer the right combination of strength and weight to allow the doors to work flawlessly for decades to come. Its impeccable powder coated finish removes the need for periodic painting, maintenance and even protects against scratches and colour fading, ensuring that the doors maintain their good looks.

Handled with care

The handles of your bifold door are the perfect finishing touch to the exquisitely designed system. Choose from a selection of elegant handle styles and rest assured that they have been designed and manufactured with the same care and dedication as every other component.

In addition to striking the optimum balance between superior strength and sleek design, handles are exhaustively cycle tested to ensure they mirror the flawless functionality of the doors and stand the test of time. Certain handle models can also be colour coordinated in any RAL colour.

Bi-Fold Corner Doors

Offering exactly the same strength, security and personalisation as our standard bi-fold doors, the corner bi-fold door ranges goes that step further to deliver the wow factor in any home.

Manufactured in the UK by highly trained craftspeople using only premium-grade aluminium, the 90° or 135° corner doors are available in a large range of configurations, colours and styles so that you can create something truly unique. What’s more, they are available as bay sets, because they understand every home is different.

Our aluminium bi-fold corner doors come in configurations ranging from two to over ten door sets, so whether your room is large or small, there’s a configuration for you.

Just like a conventional set of bi-folds, corner doors are available in many opening, folding and sliding configurations. Giving you complete control over the colour, style and formation.

Aluminium French Doors

If your opening isn't large enough for a bifold door, choose a set of aluminium french doors instead. Designed to fit into openings ranging from 1.4 – 2.4m and, for total flexibility, fixed panes can be added on either side of the doors allowing them to fit into openings of up to 4.8m.

Similar to our range of bifold and single doors in our aluminium range, french doors can be manufactured to open either inwards or outwards – whichever option is better suited to the space available in your home. Additionally, the french doors are hinged to open a full 180 degrees, truly bringing the outside in.
