What Makes Up Your Windows?

4 min read

Windows are essential for every home, but there are more parts and pieces to them than you may think. Understanding all that goes into your windows can help you better clean, maintain, repair and purchase them. We’ll teach you basic window anatomy and lingo so you can speak like the pros when your Atlanta home’s windows need some extra attention.

What Are the Basic Parts of a Window?

While there are many mechanical components to windows, you don’t need to know all the technical ins and outs to better understand their parts. Here are the most basic parts of every window:

1. Frame

The main structure that holds the window components together consisting of the jamb, head and sill.

2. Jamb

The vertical sides of the window frame.

3. Sash

The movable part of the window that holds the glass. On double-hung windows, sashes slide up and down to open and close the window. On casement windows, they swing open.

4. Lift

The handle for lifting and lowering the sash.

5. Panes

The different types of glass connected to the sash. They can be single-, double- or triple-pane for additional energy efficiency.

Key Components That Enhance Window Functionality

Windows do so much more than just provide your home’s interior with natural light. The individual components that make up your windows all have distinct purposes, from keeping rain and bugs out to increasing security. Let’s take a closer look:

1. Weatherstripping

This component around the inside frame increases energy efficiency by keeping air in and the elements out.

2. Locks and Latches

Not only do locks and latches secure your home from burglars, they also ensure the sash doesn’t rattle.

3. Balance Systems

These keep the sash moving smoothly so you can open and close your windows with ease.

4. Screens

Ideal for warm-weather use, screens allow you to open your windows for fresh air and ventilation—while keeping pests out.

Additional Components of a Window

A window is more than a frame and a pane. Here are some other window parts you should know:

1. Casing

The casing is the molding that goes around the window frames’ exterior. They seal the window frame to the house and prevent outside air from entering your home.

2. Mullion

A structural piece that connects two or more windows together.

3. Grids 

Decorative pieces that give a window the appearance of multiple panes of glass.

4. Fixed Panel

A stationary window pane that’s inoperable and is most commonly seen in single-hung windows.
