Doors that bring the ‘outside in’ such as bifold and sliding doors have seen a huge rise in popularity over the recent years. They are one of the most desirable features in any home renovation project and are a great way to create the ‘wow factor’. But which one is best for my North West home? Choosing between them simply comes down to personal preference and how much space is available.

To help you, let us share some of the main differences.

How do these two different door types work?

If, however, it is all about the view, then sliding doors may be the best option for you. In comparison to bifold doors, sliding doors open by sliding the panels one or both sides with the panes sitting nicely behind each other on two, three or even four tracks! You can choose up to four panes of glass in the patio door itself with the extra option of adding panes at the side to illuminate your home.

Are bifold and sliding doors both thermally efficient?

As a rule of thumb, thermally speaking, glass is the strong point of any product. Sliding doors tend to be more thermally efficient than bifold doors. This is because their door profile is much thicker and bulkier than the profile of a bifold door which features much more frame than glass.

However, that said, both bifold and sliding doors from Plan-it Windows offer exceptional strength and energy efficiency, so you can rest easy knowing that you and your loved ones will be kept warm all year round.

Which door type, bifold or sliding, offers greater flexibility?

With the option of including a ‘traffic door’ into the design, if you have young children who like to go exploring, then bifold doors may be the best option for you. The leaves on bifold doors fold back against themselves in a concertina style meaning that you can open them an inch or open them all the way back for full flexibility.

Whereas the typical configurations of a sliding door provide half, two-thirds, and three-quarter openings, making them the ideal opening for larger openings. If you have a large opening and you would like to open up two-thirds of it, this will give you the inside-outside feeling that we know a lot of our customer’s desire.

What colours are available?

There is a wide variety of classic colours and sensational shades to take your fancy.

Another benefit of bifold doors is that these can be made in over 150+ RAL colours giving you greater colour options to choose from. You can even customise bifold doors with dual colour, meaning that you can make a statement on the outside of your house whilst complementing your home’s interior design décor. How about Jet Black (RAL 9005) on the outside of your North West house and Grey White (RAL 9002) on the inside? Lots of our customers like Anthracite Grey (RAL 7016) too!

Our sliding doors on the other hand are available in nine different colours from White Foil to one of the most popular colours, Chartwell Green. With traditional shades to more contemporary effects, we are confident that you will find a colour you like.
