The trusted choice. Canadian made.
Folding Patio Doors
Folding patio doors, also known as bi-fold doors or window walls, use European technology built for Canadian window and door systems.
These doors open with independent glass panels that are easy to manoeuvre and can be customized to any size requirement. Wide openings maximise natural light and frame exterior views. A retractable screen operates independently, whether panels are open or closed.
Folding patio doors are fully customizable for panel size, grille design, and colour.

Folding Patio Doors Features
Built for Canadian Climates
Folding patio doors are designed for Canadian climates. Interlocking panels create an air-tight compression seal for energy efficiency year-round. With no hinges or mechanisms prone to failure in the cold, they keep your home warm in winter and cool in summer.
Full Opening Control
Glass panels open independently to any configuration, giving you full control over the size of your opening. Folding patio doors accommodate any size requirement without the limitations of a standard patio door.
Built-In Retractable Screen
Each set of folding patio doors includes a built-in retractable screen that operates independently of the glass panels and can stop at any point along the opening. When not in use, the screen tucks behind the frame, keeping the view clean and preventing dirt build-up.
All our installers are factory-trained and licensed. Before every install, we replace any faulty or deteriorating frame components on windows and doors in line with Canadian Standards Association (CSA) guidelines.
When the job is done, we leave your home the way we found it. No dirt, no dust, no debris. Every installation is backed by our 25-year transferable warranty, with dedicated after-sales support whenever you need it.

Bifold patio doors can indeed be worth it if you are looking for a stylish and functional way to connect your indoor and outdoor living spaces within your home. These doors offer homeowners a sleek and modern design, easy access, and excellent natural light and ventilation capabilities.
Window walls can be more expensive than traditional windows due to their larger size, customized installation requirements, and higher-end materials. However, window walls can also add significant value to your home, providing it with benefits such as improved natural light and energy efficiency.
The purpose of window walls is to provide unobstructed views of the exterior and to maximize natural light entering your home. Window walls can also improve your home’s energy efficiency, enhance your indoor air quality, and help create a more modern and open living space.
While they typically offer homeowners many benefits, window wall systems can also bring with them a few disadvantages, including higher installation and maintenance costs, increased risk of air and water infiltration, and reduced privacy and security. Additionally, the large glass areas characteristic of window walls can lead to higher energy bills, due to increased heat loss or gain in your home. However, their benefits definitely outweigh the drawback in the long run.
Glass walls are safe if they are installed correctly and they meet the necessary building codes and safety regulations in your region. The glass used in window walls is also typically tempered or laminated in order to reduce the risk of injury in case of breakage - however, these types of windows can still be vulnerable to break-ins, so additional security measures may be necessary.
Generally, the lifespan of a glass wall will depend on a variety of factors such as the quality of the glass and framing materials, your installation methods, and the level of maintenance you perform on your window walls. Typically, you can expect well-maintained glass walls to last for several decades, or even longer.
