Wooden Bifold Doors

Firstly, let’s talk about timber bifold doors. There are many benefits of wood bifold doors and the fact that they are aesthetically pleasing makes them a popular choice.

Their sturdiness make us feel safe and protected, all while providing a country-feel to the outside of our homes. Let’s begin by looking at the advantages and disadvantages of wooden bifolds.

Advantages of Wooden Bifold Doors

  • Timber bifold doors require very little maintenance. If treated correctly, you’ll only need to provide upkeep twice a year.

  • Timber is an extremely durable, making them a very safe option for external use.

  • Environmentally friendly and a great way to improve your carbon footprint. Older trees are used for the construction of bifold doors meaning there’ll be more room to plant new trees. New trees provide a lot more oxygen than older trees!

  • Wood adds an elegant look to your home.

  • For bringing the outside in, there’s nothing like pairing a wooden door with large glass inserts!

Disadvantages of Wooden Bifold Doors 

  • If the wood is left untreated, the wood will fade in colour and cracks will appear that will need to be filled in order to prevent draughts.

  • Over time, wood warps. Our wooden bifold doors are extremely durable and will last for many years to come.

  • Like uPVC, wood also expands in high temperatures and direct sunlight. If your door hasn’t been installed correctly or has been incorrectly measured, your door will start to stick in the frame - or you may even struggle to open and close the door. At Vibrant Doors, we measure and fit all our doors to the highest standard. For a better insight into measuring your bifold door, take a read through our bifold door sizing guide.

Wood vs. Aluminium Bifold Doors

The main thing that you’re probably wondering is the cost difference. Aluminium, when compared to timber and uPVC is the most expensive material of the three. Its sleek design, powder-coating options and it being lightweight, all increase the costs of this material to substantial heights. While the price of timber sits pretty in the middle of the three, timber doors come in a diverse range of prices to suit all budgets.

Another reason to pick wood over aluminium is that aluminium doesn’t insulate as well as wood. While you’re able to achieve an extremely slim frame, aluminium lacks insulation resulting in very little change to your energy bills - in fact, it may even raise them!

With aluminium being a poor insulator, the insulation is often heavily relied upon the glass - or the manufacturers will use another material by incorporating thermal breaks in the aluminium - which all increase the final cost.

Wood vs uPVC Bifold Doors

uPVC is the cheapest option for bifold doors. If you’re on a budget, they’re a great way to incorporate natural light into the home. However, the price tag comes at a cost.

uPVC is the weakest of all three materials making your doors susceptible to damage. Its low structural strength means that uPVC has a much lower lifespan than wood and over time, may end up costing you more in maintenance and replacements.

In high temperatures or direct sunlight, uPVC expands the same as wood does. The only difference is that uPVC can be pretty noisy as it expands. In the early morning summer sun, the cracking of uPVC is not a pleasant sound to wake up to.
