Part 2: Double Hungs, Casements, and Sliding Windows: How are they different? – Casement Windows

Windows differ depending on their mode of operation. In the first part, we talked about double hung windows and how they operate. In this part, we’re moving on to casement windows to see how the window’s mode of operation allows it offer plenty of advantages to homeowners.

The Case with Casement Windows

So what makes casement windows different from other window types? The word to remember is hinge. They do not slide upwards or glide to the sides; instead, casements open outward, thanks to the hinges at their sides. They can either be left- or right-handed units.

What makes them an attractive option?

  • Casement windows are operated with the help of a lever. The manner of operation allows one-handed use, making the window easy to operate.
  • And because casements are easy to operate, they are ideal for places that are hard to reach, like over kitchen counters and other tight spaces around the house that require window access.
  • Casement windows also feature low air leakage rates compared to other window types. This is possible because of the way sashes are designed to close, pressed against the window frame to create a tight seal.
  • This tight seal makes casements energy-efficient. Aside from helping reduce energy costs, this also lets the window ensure comfort for your home by stabilizing indoor environments.
  • Casement windows provide better ventilation control as well because sashes projecting outward offer sizable openings for air to pass through. The angles of the sashes can also be adjusted with the lever to maximize or minimize use of a breeze depending on your needs.

Making the Most Out of Casements

Because of the way they are used, casement windows require space on the outside to allow them to open fully. This means they shouldn’t be placed in parts of your home with trees and other obstructions on the other side. Aside from maximizing use of the window’s opening, keeping casements away from obstructions will also let you take advantage of its immense glass areas. The windows usually don’t use muntins so glass panes are not divided into panels. The expanse of glass lets you enjoy outdoor views, letting you enjoy the benefits of a picture window without the limitations of fixed windows.
