Let the Light in with Stunning Bifold Doors.

There is something magical about opening up the back of your house with bi-fold doors. The house feels bigger and brighter as it flows into the garden. Our summers may be short in Cardiff and South Wales but while the weather is good, bifold doors help you to make the most of it. On days that are not as bright, you still maximise the light coming into the house with more glass area and slimmer frames. Our bifold doors are built to the highest standard with premium aluminium which means that you benefit from maximum strength in thinner frames.

Which is Better - UPVC or Aluminium Bifold Doors?

When it comes to choosing bifold doors, there are many factors to consider. Quite often the restriction is the price, in which case, the decision may be clear. UPVC is cheaper. Aluminium as a material is more expensive than UPVC. While your UPVC doors will have aluminium in the frames for support, overall the cost of material means that the doors are cheaper to manufacture. It may be that the rest of your house has UPVC windows and you want your bifold doors to match in which case UPVC is a clear choice. If you are replacing windows at the same time, it may be that you compromise on one or the other to achieve your budget. We're happy to talk you through all of the options and quote for both.

There is also the option of timber bi-fold doors. We do not supply them as they require more maintenance so we will consider the difference between UPVC and aluminium.

In the early days when bi-fold doors became popular, it was clear that Upvc doors were not good enough. Modern technology has disposed of the early problems and Upvc doors are reliable. The frames have also become smaller and the runners glide smoothly.

  • Aluminium is more expensive than uPVC, but will last longer so can be a better investment. Because of this guarantees are often longer on aluminium doors.
  • Aluminium is very strong and when powder coated will last decades.
  • Both UPVC and aluminium need very little maintenance, just the occasional clean.
  • Aluminium won’t warp due to weather conditions. UPVC is more vulnerable to this depending on the quality of the aluminium inside the frame.
  • Because aluminium is so strong the frames can be slimmer allowing for more view.
  • Aluminium and UPVC are available in lots of different colours and realistic wood-grain if you like the look of timber.

Fully Customisable.

Depending on whether you choose UPVC or aluminium, you will have a range of options including which way the doors open, where the master door is placed and of course, how many doors your space is divided into. In this case, our customer chose to have glazing bars on the doors. The right door opens and the other three, fold to the left. When folded they are outside so that all the space can be used outside. We'll discuss how you use your room and help you decide. This is the most popular choice in Cardiff. Although it is normal for patio doors to be in the centre, it's usually more practical to have the opening door at the side, depending on your normal path to the doors. In this picture, the island dominates the centre so the usual path is down the right side. 


Why Are Bifold Doors so Expensive?

Bifold doors can be perceived as expensive but they are not when considered in a like for like way. Yes, they are more expensive than patio doors because they are often 4-6 doors compared to the two in french doors. When you consider the square footage, the bifold doors fill the whole space while patio doors use the walls at the side and the smaller opening. While bifold doors may use the same area as sliding doors, technically, the sliding door is much more straightforward to manufacture as there are just 2 doors and much less frame. Take into account the aluminium plus hinges, corners and frame fixings that go into 4-6 small frames rather than two large ones.

The cost will depend on several factors. The first and most obvious consideration for cost is whether you choose UPVC or aluminium bifold doors. The second consideration is quality. There are a lot of bifold doors on the market. The difficulty for you as the customer is knowing the difference. Windows and doors look the same when they are fitted. It's only in time that you start to see doors dropping because the hinges aren't sturdy enough or frames bowing because the aluminium or steel inside the frame is not strong enough. The fitting can also make a difference. Your bi-folds need to glide smoothly and this relies on level fitting. Unfortunately, the industry is known for sub-contractors who value speed over quality. That's the reason we fully employ our installation engineers. They know that quality takes precedence and will take their time to ensure the perfect installation. There is no difference in cost whether you live in Cardiff or anywhere else.

Sometimes the perception is related to house value. A set of doors costs the same whether you have a 2-bed bungalow in the South Wales countryside as it does for a 6-bedroom house in the middle of Cardiff,

How Much are Bifold Doors?

To use a much-quoted answer; 'how long is a piece of string?' It really is as diverse as that. You can buy bifold doors from DIY shops such as Wickes and B&Q. That's probably the cheapest way if that's the priority. Will they stand the test of time? It's a gamble and you won't know the answer until they fail. Single door prices can vary from around £700 - £2,500. The difference is that when you pay for quality, you can expect your doors to last a lot longer. With bifold doors, you really do get what you pay for.  Our quotes are free and without obligation so there's no harm in letting us measure up.

Can Bifold Doors Go Round Corners?

Yes, bifold doors can indeed go round corners at either a 90 or 135-degree angle. We would recommend aluminium for this. There are certain conditions that allow this to work and we would conduct a survey to ensure your opening is suitable. Cantilevered steelwork would be required to hold the roof weight above the doors. This would mean that you do not need the corner post.

The cost of doors would be the same whether you choose corner bi-folds or 2 separate units. It's the building work and labour that would make the corner door option more expensive. We are happy to explore the options with you and quote for both.

Which Blinds for Bi-fold Doors?

There are several types of blinds that can be used on UPVC or aluminium bifold doors. You can order them with integral blinds. These are Venetian blinds inside the double glazed units so they do not impede the use of your doors at all. Of course, once they're in, you cannot change them. They are a good choice if you want a modern look. They also work well if your doors open on the outside and you're inclined to leave the doors open when it rains.

There are more options available if your blinds are fitted to the outside of the profile. All of the pleated blinds usually reserved for conservatories are suitable for this and offer super choices of fabric including blackout and thermal protection if your doors are south facing. These blinds can be either screwed into the frame or fitted with clips. The two popular clip-in systems are Intu and Perfect Fit. You need to be wary of these as the Perfect Fit has a frame all the way around, and the Intu has a frame at the top. Both of these options sit on top of the door frame so they may stop your doors from folding flat. The screw-in conservatory blinds normally fit within the recess of the door. Some of the aluminium bifold doors have a shallower profile so check this before ordering. Check with your supplier that this will not affect the warranty.

It isn't popular in Cardiff to have curtains at the side as they hang over the window. If you still have a preference for curtains, a style where they hang straight in tubes may be preferable to one where they are draped across the window and held back with tie backs. One of our Cardiff customers was adamant that they wanted curtains, so in this case, we suggested making the opening smaller to allow for a small wall at the side. This saved money on the bi-folds and allowed space for the curtains.
