A folding patio door is one of the greatest investments you can add to your home. It brings various benefits such as improving your home’s design, adding value to your property, maximizing your home’s natural light, and creating a space for entertainment.

Folding patio doors come in numerous shapes, finishes, and configurations and will definitely spruce up your living space.

What Is a Folding Patio Door?

A folding patio door is also known as a bi-fold (or bifold) patio door or an accordion patio door because when it is opened, it folds like an accordion. It is made up of three or more panels that are connected with hinges and can fold to open or straighten to close.

When patio doors are closed, they form a wall of glass. Folding doors can either be in-swing or out-swing. The difference is when in-swing doors are opened, they fold and stack neatly indoors, while out-swing doors stack neatly towards the outdoors and create a big opening.

You can get bi-fold doors to either upgrade your current patio door opening or replace a part of your wall to get a seamless transition from your interior to exterior spaces such as an outdoor kitchen, a patio, or a gazebo. They create a substantial opening when opened and still allow maximum light inside your home when closed.

Types of Folding Patio Doors

There are many different door designs, colours, and finishes to choose from that you may be spoilt for choice. Bi-fold doors can be made with materials like aluminum, wood, vinyl, wood, or fibreglass frames. You can look for various folding patio doors in the Ottawa area and find different options such as:

1. Accordion patio doors

Accordion patio doors stack together inwards, outwards, or even on themselves sometimes. They can be engineered of two or more glass panels which create an impression of more space without structurally changing your home.

2. Bi-fold patio doors

These doors are also known as two-panel folding doors and comprise two large glass panels. Most bi-fold doors are usually made using energy-efficient glass. They also increase your home’s airflow while maximizing natural light.

3. Tri-fold patio doors

They are similar to bi-fold doors but have more layers or stacks. As the term connotes, tri-fold patio doors have three panels that pile vertically on each other.

Benefits and Features of Folding Patio Doors

Accordion folding doors are increasingly becoming a go-for option for homeowners in Ottawa due to the following reasons:

1. Create more space and are safe for kids

Folding patio doors with screens will make your living room look more spacious and brighter. Bi-folding glass patio doors also provide more visibility in your house and compound. Therefore, you will be able to watch your children play outside while continuing with your daily duties.
