Wood bifold doors

Timbers like oak or spruce have a range of positive natural attributes that make them the perfect material for constructing doors. For one, they offer great insulation values and they're highly resistant to force. Wood also 'breathes', which can slightly improve air circulation in a room. And, of course, wooden bifold doors just have that amazing woodgrain look to them. Large external bi-fold doors made of wood also let plenty of natural light into your home, while the folding leaf system allows you to open and close them quickly and effortlessly.

Fully customised wooden bifold doors

Bi-folding doors feature multiple sliding leaves, each consisting of a casement and a large glazed panel. This allows them to be extremely wide. Bifold doors made of timber (spruce, oak, etc.) in large sizes can easily cover the entire length of a room. Choosing the right design and colour is just as important as choosing materials with good insulation properties and resistance against force. The RAL colour palette features countless colour finishes to pick from, allowing you to find the perfect fit for the exterior (and interior) design of your home. And since this type of door features so many individual leaves, choosing the right material for the casement can impact thermal efficiency more significantly compared to other door types.

Features and options

Any exterior door leading to the garden, a balcony, or the patio needs to be resistant to burglary attempts. At windows24.com, you have plenty of options to maximise security depending on where you want to install your bi-fold door. With an oak patio door, you should consider adding laminated safety glass and locking handles. With a French door, you may want to choose structured or ornamental glass to allow your door to act as a privacy screen.

Buying wooden bi-fold doors

Compared to normal sliding doors, bifold doors really aren't much more difficult to install. That's why experienced DIY enthusiasts can easily avoid hiring a costly professional builder. All you need are the proper tools for the job, a few helping hands and detailed installation instructions. You'll have your new oak bifold patio doors installed within a day's time. Take care to adjust your newly-installed doors, though, as both burglary protection and insulation efficiency rely on properly closing seals and leaves that are flush with the oak frame.

Further information

Convenience and security – why install a bi-fold door?

What makes internal or external bi-fold doors so unique is the way they open and close: internal or external bi-fold doors consist of multiple leaves (each consisting of an oak or spruce casement and a glazed panel) which fold together like a concertina. This offers a number of benefits over normal slide doors:

  • They can cover a wider area.
  • You can open the door only partially or completely.
  • Feel safe with increased burglary protection.  

This makes them a safe option for porches, gardens and balconies.

The most convenient thing about external or internal bifold doors is that you can open them either completely – to move large objects through, for example – or you can only open a couple of segments if all you want to do is let in some fresh air.

Folding leaves glide along their guide rails effortlessly, making folding patio doors much easier to operate than you'd think based on their sheer size. And the best thing is that the oak leaves require much less space when they're opened. Where a large tilting door may require lots of space around the leaves to swing open, bifolding door leaves fit neatly together when opened.

Thermal insulation

Bifold doors differ from normal slide door sets in terms of insulation. Since bifold doors consist of multiple individual oak segments with glazed inserts, the frame makes up a larger surface area compared to doors consisting of only one sliding leaf. Since modern clear glass inserts insulate even better than solid wood (spruce, oak, etc.), this means the overall thermal efficiency of bifold doors tends to be slightly minimised compared to other types of sliding exterior or internal doors made from the same material.

So if you'd like to install a bifold door in your home, make sure you maximise its insulation values by choosing top-grade wood (spruce, oak, etc.) or multi-chamber uPVC profiles. You can also improve the thermal efficiency of your oak bifold doors by using three-pane glass panels or insulated spacers. Keep in mind that bifold doors (especially with large sizes) need to be adjusted properly so the seals between the frame and the leaves seal tightly.

Only ever rely on high-quality seals, as no amount of re-adjusting will prevent bad seals from leaking warmth to the outside. At windows24.com, we take special care to only use highly advanced seals to manufacture our bifold doors. We also provide you with clear instructions on how to adjust and re-adjust the leaves without outside help.

Frequently asked questions

Unlike materials such as aluminium, timbers like oak or spruce are a natural resource from sustainable sources – which makes them an even more popular material for windows and bi-fold door sets. They do have their price, though, with the larger doors as well as doors with greater installation depth being more costly than smaller ones. With the windows24.com online configurator, you can customise your new spruce or oak bifold door before manufacture to ensure they fit your wishes precisely – while keeping an eye on the price. Our configurator shows you the final price of your bi-fold door set, with all extras and options already included.

Timber combines good insulation and durability with the amazing look you've come to expect from high-quality hardwood or softwood. That's why wooden windows and external or internal doors are so popular. When customising your new bifold door with windows24.com, you can choose between different hardwoods and softwoods, including spruce, meranti and oak. If you're looking for an even more robust door that's highly resistant to warping, you can also opt for an aluminium composite construction with an internal wooden core and an aluminium shell on the outside.

Depending on the type of timber you've chosen, you can apply a range of colours to the frame and leaf. We use environmentally friendly water-based finishes during manufacture. Choose the RAL colour that fits best with your home and enjoy your fully customised internal or external bifold door.

Yes, you can. Bars are a popular design element that can make any modern window or oak door look timeless. You can choose from Helima bars (internal bars), Vienna bars (sitting on the glazed surface) and glass-partitioning bars. You can even choose how many bars you want and how to space them out.

You can order our oak, spruce or meranti external bifold doors with up to five leaves for particularly wide door sets offering an amazing view of the outside. The next step is to decide on how these leaves should open. You can even decide to have one leaf pivot out like a normal single door and have the other leaves fold together.
