  • Casement windows are recognized as one of the most convenient and popular window styles for modern homes. A casement window consists of vertical panes hinged on the side so that they can swing open like a door. The casement is operated using a mechanical crank or handles which pivot it inward or outward. While the side-hung casement is the most popular configuration, you can have top-hung or awning windows in which the sash hangs from the top. Casement windows have been gaining popularity with homeowners because they offer a simpler, modern, and more streamlined aesthetic. In this article, you will learn about replacement casement windows, their parts, benefits, challenges, and how you can use them for your next home remodel.

Parts of a Casement Window

A casement window consists of several components. Each of the casement window parts assist with the window’s overall functionality. The outer edge of the casement window that attaches to the wall is called the window frame. The frame is typically surrounded by a casing, which is the decorative filling between your window frame and the wall. The part of your casement window that swings and holds the glass panes is called the sash. Frames and sashes are constructed from various materials including metal, vinyl, wood among others. On one side of the sash are hinges which allow it to swing open. Casement windows usually come with a crank handle at the bottom to help with opening/closing. Most casement windows come with horizontal stays that support the sash when open and latches that secure it when closed. Lastly, their are casement window screens that are options that are offered as a window replacement option.

This window option is commonly used as a mechanism that allows ventilation and airflow in basements, bathrooms, or upper floor rooms. The bottom hung window is also know as a hopper window.
  • Top hung casement – Window is Hinged at the top of the window frame and opens outward from the bottom of the window. This window option option provides similar functions as the bottom hung but it further helps to prevent rain and water from entering the room.

Challenges/Common Issues

Breakage of Mechanical Parts

Casement windows may develop problems with the crank, latches or handles. These parts may rust, break or freeze. The common mistake which causes these issues is neglection and irregular maintenance. To avoid these issues from happening it is recommended you periodically oil the parts to keep them lubricated, keep the parts as dry as you can, and operate them gently.

Components are Exposed

Various parts of your windows are exposed to the wind, snow, and rain because the window opens outward. These extreme elements over time wear down and damage your window. To combat exposure to harsh elements, always close the sash as soon as it starts to rain/gets windy.

Breakage of Sashes

When the wind catches the leading edge of your casement window sash, it can break them with a sail-like effect. Wind gusts tend to break off your hinges in violent weather. If your home lies on the windward side, you can invest in exterior screens and storm windows to provide protection during the windy season.

Conflicting Casements

If you reverse the swing in adjacent windows, the open sashes will conflict. You should consult and review the work with your contractor before installation to ensure that any potential anomalies are prevented or corrected.

Sun Reflection

Open sashes can occasionally reflect sunlight directly into your house. This makes your home’s occupants uncomfortable due to the piercing effect. You can solve this by turning the sash from a different angle.
