What’s the Difference between Sliding and Casement Windows?

      Comments Off on What’s the Difference between Sliding and Casement Windows?

When it comes to window replacement, there are many options homeowners can consider. Sliding and casement windows are among the most popular and energy efficient choices. They differ in many other ways, including their physical structure. The width of a sliding window is greater than its height, and this configuration is part of what allows one pane to slide sideways over another. Taller and narrower, casement windows attach on one side, and swing toward the outside; they are crank, handle, or lever-operated and are suited for tall, narrow openings.

Efficient but Different

A sliding window is almost as efficient. However, it requires a flexible seal since the window opens and closes. A different type of seal is needed for a casement style window. This seal isn’t flexible, so provides a more airtight fitting that makes casement windows more energy efficient.

Safety Always Matters

Casement and sliding windows are both safe. One can argue that the mobility of a sliding window creates a security risk, but latching it makes it as safe as a casement fitting, which will easily pry open if you don’t have the latch secured. Criminals have another way to get in regardless of the window type – just break the glass. Therefore, safety usually isn’t a factor when choosing one type over the other.

Ventilate Your House

Many choose window replacement to boost ventilation. You can open any window to let air in; however, casement windows allow you to open the entire thing, letting air in through the entire surface area of the frame. Only half of a sliding window can be opened at a time. It depends on how much ventilation you need, but casement-style is the way to go if you want maximum air flow.

Cost

Slider windows are often cheaper, but they can be a challenge to open. That’s why it is advisable to go with a quality model. Since they are more sophisticated yet easier to operate, casement windows tend to cost more. They do have more features and options to work with, such as lift rails, rollers, and reinforced sashes. Some casement windows open to a 90-degree angle, which increases airflow and simplifies cleaning.

Pros and Cons

Casement windows offer more flexibility in terms of customization, and are the more efficient option. In addition to air flow, they provide a security boost because the lock is built into the frame. Many find sliding windows easier to operate, as there are fewer mechanical parts, and they blend in with refurbished houses and older structures. Even though you can open just half the window, you can adjust how much air you want to flow in by moving the panel farther in or out.

The main downside with a casement window is it presents more of a safety hazard if left open unattended. Sliding windows are a little less energy efficient.
