Bi-Fold Doors explained by Polar Bear Windows, Doors & Conservatories of Bristol, Bath and Somerset

Bi-Fold Doors have become more and more popular over recent years with so many benefits and they make a brilliant alternative to traditional French or sliding doors in a home or business.

What are Bi-Fold Doors?

Bi-fold doors are made up from a series of panels that fold up flat against an inside or outside wall in one movement, much like a concertina.  They are a great way to combine and open up your home into your garden and vice versa, as well as giving you a great view out into your garden when they are closed.

Why would you have Bi-Fold Doors?

Bi-folding doors help to create the illusion of space and this comes from their slim frames and the large expanse of glass panes that draw you to look beyond the end of a room and out into the garden or outside area.

Are Bi-Folding doors practical?

Bi-folding doors give you a very modern and stylish look as well as having many practical benefits compared to other types of doors. The main reason people choose to have bi-fold doors is that they create a bright and open feel to your home or business when you are inside with uninterrupted views to your garden, and when they are open and folded back flat they open up your home into your garden and vice versa.

What are Bi-Fold Doors made from?

Bi-Folding door frames can be made from uPVC, aluminium or wood and there are pros and cons to all of them; uPVC bi-folds tend to be cheaper, however, aluminium is the better option for larger openings due to their superior strength and durability (3 times stronger than uPVC). Wooden bi-folding doors are the more expensive option. The majority of bi-fold fitted in the UK are made with aluminium frames.

How many panes of glass can you have in Bi-Fold Doors?

Bi-fold door panels standard sizes are normally 2090mm or 2100mm tall, and this is only slighter taller than a standard internal door. You can have anything from 2 to 6 panes in your bi-fold doors and this all depends on the width of your opening. Some people choose to have them the whole width of their room which gives a dramatic, modern and open feel.

A bi-fold door with several panes of glass can be configured in the same way as a door with fewer panes. The panes can all fold in one direction, left or right, or they can be split to open in both directions. The more panes you have in a bi-fold door the more it is suited to opening in both directions either side, as you need a lot of space to have 6 panes stacked at one side. You can have access doors incorporated into your bi-folds to make it easy when you don’t want to have to open them up completely to access inside or out.

Which way should a bi-fold door open?

A bi-fold door can open to the right, the left or from the middle and they can concertina inside or outside the door opening. The space outside of your property will dictate if they can open inside or out. Most people choose for them to open and stack outside to ensure there is no restriction on furniture inside of the door opening.

What are the benefits of Bi-Fold Doors?

What are the disadvantages of Bi-Fold Doors?

–    Each pane of glass has its own frame and when they are closed you can see the slim frames, however, the design means you can open them up completely and join your inside and outside space

–    Your choice of frame colour is an important consideration to ensure they match with your interior décor when they are fully closed. Always remember that darker coloured frames will highlight their structure

–    Although the lack of a raised threshold is positive in so many ways, if they are not installed correctly it can cause potential issues. In these cases, groundwater can be blown inside. This can be prevented with a drainage system if needed

–    If you stack the doors inside it can limit your space for furniture

–    Bi-fold doors can cost more than other types of doors due to their framing and the quality and amount of glass in them. Always shop around for quotes from a reputable window and door companies, such as Polar Bear Windows and Doors, that you trust. The frame material, type of glass and finish will all affect your price. Always check if the installation is included in your quote as this will vary from supplier to supplier.
