Bifold doors can be a great investment for improving the home and utilising natural light. Offering slim sightlines, durable materials and a perfect way to bring the outside in – bifold doors can be an invaluable addition to your home. However – before purchasing a bifold door, you may be considering factors such as how long they take to install, and how much it will cost to install an external or internal bifold door.

Here, we look at how much it costs to install bifold doors, what affects the cost of bifold doors installation.



What factors can impact the cost of a bifold door?


If you’re wanting to install bifold doors cost-effectively it’s a good idea to get to know the areas that can bump your prices up so you know what to expect when it comes to cost:


Your chosen bifold door frame material

Bifold door prices vary depending on the type of door frame material, as some materials are more durable and low maintenance than others. Aluminium used to be considered one of the costliest materials but has since come down in price slightly and can make for a durable investment. However, you may still find that aluminium doors are typically slightly pricier than other materials.

Timber bifold doors are incredibly popular due to their good quality/aesthetic, and provide a traditional feel. They are typically slightly less pricey than aluminium and composite bifold doors, so can make a cost-effective option

Composite offers the best of both worlds, combining the benefits of an aluminium door and a timber door - offering excellent thermal properties and low maintenance. On the other hand - UPVC was known to have been one of the cheapest materials for bifold doors. However, recent findings have dictated that the average price of a uPVC bifold door has increased.

Single glazing typically offers thin, poor insulation, and is an expensive investment considering the results. Double insulation, however, is arguably the most-effective option, sold at reasonable prices and providing average insulation thickness.

Triple glazing, on the other hand, is the priciest option, and you can expect this option to impact the price of your folding door significantly. However, this option does provide the thickest thickness option, and the most impressive results. It is the perfect option for keeping the cold out and heat in during winter, and is also very effective in keeping your home cool in the summer.

Location of the door

Is the bifold door internal or external? External bifold doors are typically more expensive, due to stricter measures required for security, thermal efficiency, and more. Whereabouts you are installing the bifold door may also have an impact on the cost of the door, as this can dictate size, thermal requirements, configurations, and more.
