Basement Windows

Basement windows are quite literally the windows that remain in the shadows. Less visible, they tend to be more practical than aesthetic. In fact, there are key differences between the window needs of upper floors and those of a basement. Whether in terms of functionality or applicable standards, basement windows must be considered differently than the other doors and windows in your home.

Types of Basement Windows

Unlike standard wall windows, basement windows can’t accommodate all types of openings or glass widths. Installing a bay window in a basement, for example, would be highly unusual! The most commonly used type is the sliding window—an affordable and convenient option.

You’ll also find some casement windows in basements. However, awning windows are rarely used, and hung windows (single or double) are almost never installed in basements, as they simply don’t meet the needs.

Sliding and casement windows each offer several advantages, which is why we often recommend these models. Sliding windows are ideal because they require minimal space to open—particularly useful when the window is installed in a window well.

Casement windows are also a great choice. Their slim frames and lack of visible hardware allow more light to enter a confined space. Additionally, the way they open makes them compliant with building code standards enforced by the RBQ (Régie du bâtiment du Québec), just like sliding windows.

Basement Windows and the Egress Standard

Every home or dwelling in Quebec must have two exits, in case of a fire. In the basement, a window may serve as a second means of escape.

The building code also requires that any room in the basement considered a bedroom must comply with emergency exit standards (unless the building is equipped with a sprinkler system).

These standards—referred to as “Egress”—can be enforced by municipalities through inspections and fines, or by insurance companies after an incident. It’s important to follow them to avoid injuries or complications. Here are some of the main rules for basement bedroom windows:

• The window hardware must be simple enough for a child to open and use as an exit in case of emergency. The window must be operable from the inside without keys, tools, or the removal of any sash.

• Hardware must not obstruct the emergency exit. This is one of the main reasons awning windows are usually not used in basement bedrooms—they violate the basement window code requirements.

• The clear opening area of the window must be at least 3.77 square feet. The minimum height or width of the opening must be 15 inches.

• There must be at least 760 mm (30 inches) of clearance in front of the window on the outside. If this is not possible, a window well must be excavated to meet this rule.

If your basement bedroom window doesn’t meet these standards, speak with a representative from Portes et Fenêtres Verdun. We can help you find the right solution—whether it’s modifying the hardware on an existing window, replacing it with a different model, enlarging the opening, or constructing a window well. It’s also a great opportunity to improve your home’s energy efficiency.
