What Is a Casement Window?
If you’ve ever wondered what is a casement window, you’re not alone. These popular, easy-to-use windows have become a staple in modern and traditional homes alike. At Builders Service Company, we’ve been helping Washington homeowners upgrade their windows since 1974. In this guide, we’ll walk you through everything you need to know about casement windows, their benefits, comparisons, and how our team can help you make the right choice for your home.
What Is a Casement Window?
In simple terms, a casement window is a window that is hinged on one side and opens outward to the left or right, like a door. Instead of sliding up or sideways, these windows open using a crank mechanism, which is why they are also commonly referred to as crank windows.
- Hinge mechanism: Attached to the side of the window frame
- Crank handle: Easily turns to open or close the window smoothly
Casement windows are designed to provide superior airflow, energy efficiency, and a sleek, modern appearance. So, what is a casement window good for? Many things, as you’ll find out below.
How Do Casement Windows Work?
Casement windows work with a side-hinged design and open outward, typically with a crank arm. Here’s how:
- The crank arm pushes the window sash open, allowing it to swing outward
- The window can be opened fully to the left or right for maximum ventilation
- The handle is usually fold-down or easy-turn, keeping the window design clean and user-friendly
If you’re still wondering what is a casement window mechanism, it’s that easy-to-use crank system that sets it apart.
Where Are Casement Windows Commonly Used in Homes?
Casement windows are extremely versatile and fit well in various rooms:
- Kitchens: Especially above sinks where reaching is difficult
- Bathrooms: For enhanced ventilation and moisture control
- Sunrooms/Sitting Rooms: To maximize light and outdoor views
- Bedrooms and Living Areas: Where unobstructed views and fresh air are desired
Now you see, what is a casement window best used for? These specific spaces benefit the most.
Benefits of Casement Windows
Here’s why casement windows are a homeowner favorite:
- Maximum Ventilation: Opens fully to let in more air than sliding or double-hung windows
- Unobstructed Views: No bars or rails in the center of the glass
- Easy Operation: Smooth crank handle ideal for hard-to-reach spaces
- Energy Efficiency: Tighter seal reduces heat transfer and lowers utility bills
- Easy Cleaning: Many designs open enough for both sides to be cleaned from inside
- Sleek Aesthetic: Offers a modern, streamlined appearance
- Enhanced Security: Multi-point locking systems provide better protection
- Design Flexibility: Can be combined with other window shapes
If someone asks you what is a casement window advantage, now you have plenty to share.
