Casement windows, also known as crank windows, are a type of window that opens outward using a crank mechanism mounted at the bottom of the frame. Known for their ease of use and excellent airtightness, they are a reliable solution for all types of residential buildings. This is the most popular window model in Quebec due to its performance, user-friendliness, and exceptional sealing.
Unlike sliding or sash windows, casement windows open fully to the side, allowing optimal ventilation—even in light wind. This full opening also makes them easy to clean from the inside and maximizes the flow of fresh air and natural light.
Crank-operated windows allow for a wide lateral opening, which enhances natural ventilation, simplifies maintenance, and increases light entry. This system, combined with a multi-point locking mechanism, applies even pressure on the weatherstripping to prevent any air or water infiltration—making it an ideal choice for Quebec’s climate.
One of the most popular models is the PVC casement window, valued for its excellent quality-price ratio, durability, and low maintenance. It is also available in hybrid versions (PVC-aluminum) or entirely in aluminum to suit various architectural styles.
Casement windows are especially recommended for strategic areas such as kitchens or bedrooms, where airflow is essential. Available in a variety of sizes, they can be installed on their own or combined with a fixed window.
Durable, high-performing, and easy to operate, crank windows are a safe choice for both renovation and new construction projects.

What’s a hybrid window?
FAQ
During the cold season, it isn’t unusual to see condensation on windows.
Here are a few simple tricks to reduce the amount of condensation on your windows during the winter.
Air out the inside of your home every day.Open your windows or doors for 10 minutes and let the air circulate.
Use your air exchanger.An air exchanger vents stagnant air to the outside of the home. Don’t have an air exchanger? You can use a fan to circulate the air inside your home and prevent microclimates.
Leave your blinds and curtains open as much as possible.This will allow the air to circulate freely, preventing moisture from becoming trapped between the glass and the curtains.
Heat the inside of your home adequately.This will help reduce humidity levels. It will also heat the outside of the window, decreasing the amount of condensation.
Wash your windows using dish soap. Wipe down your steamy windows with a dry cloth moistened with dish soap and then wipe them off with another dry cloth to remove any traces of soap.
Use a dehumidifier. Keep the relative humidity below 60 percent to prevent excessive moisture inside your home, and thus on your windows. Whether you use a portable dehumidifier, a heat pump or your air exchanger, it will prove quite useful in preventing condensation.
A hybrid window uses one type of material for the inner frame and another type for the outer frame.
The manufacturer combines different materials to optimize the unique advantages of each one. The most well-known hybrid window has an interior frame made of PVC, which is covered by aluminum on the outside. You’ll also find wood-aluminum hybrid products on the market.
