Vertical Bifold Window vs Horizontal Bifold Window

Bifold windows are a popular choice for modern homes and commercial spaces as they offer a seamless transition between indoor and outdoor areas. They come in different styles and configurations, with the two most common being vertical bifold windows and horizontal bifold windows. While both types serve the same purpose, they differ in appearance and functionality. In this article, we will explore the differences between vertical and horizontal bifold windows to help you make an informed decision when choosing between the two.

What is a vertical bifold window?

Vertical bifold window systems are made up of two frame panels that can be folded on top of one another and moved vertically. This system is similar to the horizontal bifold windows, but with a few important differences. This can be referred to as a vertically bifolded window or a fold up window.

What is the differences between vertical bifold window and horizontal bifold window?

They differ primarily by their orientation and the way they work. Here are some of the main differences between horizontal and vertical bifold windows.

1. Orientation:

  • Vertical Bifold Windows – Vertical bifold windows open and close vertically, with the panels folding up and down. This style works well for spaces with high ceilings or those that require more height than width. Vertical bifold windows also create a sense of height, making them ideal for homes or commercial spaces where natural light and ventilation are essential.
  • Horizontal Bifold Window: By contrast, horizontal bifold windows open and close horizontally, with the panels folding left and right. This style works well for spaces that require more width than height, such as patios, decks, and balconies. Horizontal bifold windows offer unobstructed views of the outdoors and create a seamless transition between indoor and outdoor areas.

2. Functionality

  • Vertical bifold windows are typically operated using a crank or motorized system, making it easy to open and close them. They are also easy to clean and maintain, as the panels can be removed for cleaning or replacement.
  • Horizontal bifold windows, on the other hand, can be operated using a track system or a handle that pulls the panels open or pushes them to close. They are also easy to clean as the panels can be removed for cleaning or maintenance.

Energy Efficiency

Both vertical and horizontal bifold windows are designed to be energy-efficient, but they achieve this in different ways. Vertical bifold windows are designed to seal tightly when closed, which helps to reduce energy loss. Horizontal bifold windows typically have a lower air leakage rate, which helps to improve their energy efficiency.

How does a vertical bifold window work?

Vertical bifold windows are available in both manual and motorized versions, allowing for flexibility and convenience depending on the user’s preferences and application. Here is a quick overview of each type.

1. Manual Operation

  • Handle Mechanism: Vertical bifold manual windows are usually equipped with a crank or handle mechanism. The handle is attached to a mechanical system or gears. This initiates the folding of the panels and their stacking.
  • Manual Operation: This allows the user to control the speed and size of the opening. This is a simple and reliable method that’s ideal for small window installations.

2. Motorized Operation

  • Electric Motor System – Motorized vertical bifold Windows feature an electric motor which automates opening and closing. The motor can be controlled by a wall switch or remote. It can also be integrated into an automation system.
  • Convenience and precision: Motorized systems offer a high degree of convenience, particularly for heavier or larger window installations. These systems are perfect for windows that are difficult to reach, and their automation allows them to control the opening degree precisely.
  • Safety Features: Some motorized windows include safety features, such as obstruction sensors that detect an object in the path of the window and stop or reverse its operation automatically to prevent damage.

Considerations to consider when choosing between manual and motorized:

  1. Size and weight: A motorized system is more convenient for larger and heavier windows. It will ensure smooth operation.
  2. Budget: Manual systems tend to be more cost-effective than motorized ones. Budget considerations play a part in deciding the best option for a project.
  3. Convenience – Motorized systems provide the convenience of automation or remote control. Motorized systems are a good choice if ease of use, particularly for windows that are used frequently, is important.
  4. Accessibility: Motorized windows are ideal for those difficult-to-reach locations, like high ceilings and installations above countertops.
  5. Integration with Smart Home Systems. If you already have a smart system in place, a motorized bifold vertical window can be seamlessly integrated to control other automated features at your home.

Manual or motorized, vertical bifolding windows offer the same unique benefits, such as a space-saving, sleek design and seamless indoor/outdoor connection. The decision between the two options will be based on project specifications and personal preferences.

Vertical bifold or horizontal bifold, which is more expensive?

The vertical bifold window is only available with an aluminum frame. However, the horizontal bifold window is available in both aluminum and uPVC frames. The price of an aluminum bifold window is similar for both vertical and horizontal models. Both types can be customized for aluminum frame color, glass, and mosquito screen. The uPVC horizontal bifold window is more expensive than the aluminum bifold window due to the costly ROTO hardware.


Both vertical and horizontal bifold windows offer excellent natural light, ventilation, and a seamless transition between indoor and outdoor areas. The decision between the two types mainly depends on personal preference and the design of the space where they will be installed. Whatever your choice, bifold windows are an excellent investment for any modern home or commercial space.
