Casement Window Basics

Pros

Casement windows open outward, so they provide effective ventilation. However, they are also one of the most energy-efficient types of window available because their design allows for a tighter seal between the frame and sash than other types of windows. This tight seal permits less heat to escape. Casement windows are also ideal for spots in your home that are difficult to reach, such as above a sink or other built-in features, because they open with the simple turn of a crank. In addition, they provide an effective escape route in case of a fire or other emergency.

Because casement windows open outward, their hinges and hardware must be in top condition in order for the window to open and close properly. If your casement windows are older, you may notice rusting or other deterioration in the hinges that affects operation of the windows. In addition, if the hinges and hardware begin to show signs of wear and tear, it becomes easier to break into casement window. As a result, you need to monitor the hinges and replace them at the first sign of deterioration.

Installing casement window is a fairly straightforward process. If you enjoy do-it-yourself projects, you can likely handle the task. Begin by checking the rough window opening to make sure that it is plumb and level, and apply flashing to protect the window according to the manufacturer's instructions. Before placing the actual window, apply latex caulk around the entire opening to seal the window in place. Align the window so the bottom fits on the sill plate, which typically means that it will be centered approximately 1/2 inch between the jack studs and the side jambs. Use corrosion-resistant finishing nails to secure the corners. Remember to check the window's plumb and level again to ensure that it fits properly. Test the window by opening and closing it several times. If your casement windows are made of wood, cover the wood with a latex primer and two coats of latex paint. Transparent stains are usually not sufficient for protecting exterior wood.

To ensure that your casement windows last, proper maintenance is essential. As with all windows, you should clean the glass on a regular basis. A soft cloth and a glass cleaner spray usually work well. With casement windows, protecting the hinges is a priority as well. Lubricate them regularly to ensure that the windows open and close smoothly. You can use a lubricating spray from a hardware or home improvement store that makes the chore very easy.
