What are Casement Windows?

Casement windows swing open, usually by a user-friendly hand-crank located at the bottom of the window. They are easy to use and excellent for providing ventilation, because the entire window opens outwards. They are great for high or difficult-to-reach locations, in which normal windows would be difficult to operate. Also an excellent option for the physically challenged.

Are Casement Windows Right for My Seattle Home?

Casement windows are a popular option due to their ease of operation, the superior ventilation they provide, and because they’re gasketed around all sides, which makes them a little more energy-efficient than sliding windows. In addition, they are available in attractive designs that will add to your home’s overall appearance.

Casement Window Pros

Easy Operation

The hand-crank is usually fairly easy to operate, but if you have concerns make sure you mention them to the casement window installers before placing an order. They will be able to help you find a product that fits your needs and abilities best. Generally, casement windows are one of the best options for people with limited abilities, or for places where other windows are hard to operate.

Energy Efficiency

The seal of casement windows are great for Seattle weather changes. The superior quality seal insulates the home maintaining warmth in the Seattle Winter and cool in the Summer.

Casement Window Cons


Casement windows usually cost more than other window types because of the superior quality seal, and because they need sophisticated hardware in the crank mechanism. These features are what make the windows so energy-efficient and convenient, however, so the price is usually well worth it.


Two possible downsides of casement windows are that on older windows the crank mechanism may need some repair, and it may be hard to reach the exterior of the window from inside your home for cleaning or other purposes.
