Which to Choose, Casement or Bifold Windows?
Changing from casement to Bifold Windows.
It’s probably fair to say that casement windows are the most frequently installed double glazing these days. Why not be different to the crowd and take a look at what Bifold windows have to offer?
What are the differences between Casement & Bifold Windows?
It all comes down to the way each design functions. A Casement & Bifold window operate using significantly different methods.
The 3 types of casement window that you can find all open outwards via hinges on either the top, bottom or side of the movable section.
Top hinged variations are sometimes referred to as an “Awning windows”, whereas bottom hinged versions are sometimes referred to as “Hopper windows”
Whilst modern double glazed window hinges allow for quite a wide arc of travel, the window will only ever open so far (less than 90 degrees of movement).
This means that the window itself blocks some of the view even when fully open.
Bifolds (or multi-fold), on the other hand, do not rely on a single opening section. A typical Bifold window will consist of 2 or more glazed panels that slide to the side. Whilst being slid to the side the panels “fold” in a zig-zag fashion until they “stack” completely out of the way at the sides of the outer frame.
The panels are held in place by means of built in tracks at the top & bottom of the frame. Which allows the windows to open to both left or right. If you have several panels, you can also select some to move right & the others to move left.
Once opened fully, Bifold windows leave a huge clear opening, so that your views are unobstructed and allows for the maximum amount of ventilation.
One other advantage this design has over casement is practicality. With a casement window, to open it fully you will have to lean out in order to attain maximum opening. In order to close it again, lean out to grab the handle to close it. With bifold windows, the handles only move side to side, so no precarious balancing acts are needed to open or close them fully.
A more recent trend is to create a “servery” window. By having an extended window sill on the outside you can create a nice breakfast bar or casual eating area for family or friends.

Advantages & Disadvantages of Bifold Windows
Firstly, and maybe most importantly to some folks, Bifolds are usually costlier than standard casement windows. For those on a tight budget, this could be a deal breaker.
Secondly, because there are more moving parts, potentially there are more things that could go wrong.
Thirdly, once again due to more moving parts, there will be more weather seals. These seals need to be high quality to keep out wind & water.
Having said all that, if you have the budget, then especially in ground floor areas like the lounge, diner or kitchen, we think that Bifold windows are the best choice.
