How can you improve your home’s look, give it a better curb appeal and improve its energy efficiency? You can do all this by removing old windows and installing new ones. However, before you go shopping for windows, you need to know what you’re looking for.
This starts with learning about the different parts; thus, ensuring that the manufacturers and installers you use will give you the kind of windows (and look) you want and desire. In the below guide, we’ll review the parts of a window, so you can make an informed buying decision

The balance is the mechanical device used to counterbalance the sash’s weight during both opening and closing – be it a single-hung window or a double one.
The window frame supports the whole system and is made up of the sill, jamb and head.
Inside the window frame is a piece of glass to keep the elements out and the cool/warm air in.
This part of the window is located at the top of the frame and is horizontal.
The vertical part of the window create the window frame’s sides.
These are the strips added to the window sides to ensure a snug fit for the sash.
This involves a handle, which lifts the lower sash.
A double-hung window has three rails. The upper and lower ones are situated on the horizontal part of the sash. In the middle is the check rail. It’s where the upper piece of the lower sash links to the bottom piece of the upper sash.
The sash is what holds the window in place even while it’s moved.
This locking apparatus clicks with the sash lock strike to eliminate any rattling.
Often called the stool, it’s the primary horizontal part that makes up the bottom part of the frame.
These are located on the window sill and are individual openings that ensure condensation and water escapes.
Other Parts of a Double Hung Window
This is the window’s ornate frame or molding that closes up the space between the wall and jamb/frame.
Exterior Aluminum Cladding
A window’s outer part is generally encased by extruded aluminum and has a factory finish to protect the window from the elements.
This part of the window doesn’t move and is more of a sidelight or accent to it.

Additional Structures That Make Up A Window
This decorative trim is located under the window stool, giving the window interior a sleek, modern design.
The kind of window you have determines the hinges’ location. If you have a casement window, the hinges on the jambs of the non-opening side. For an awning window, the hinges are located on the frame head as the window opens up from the window. On hopper windows, the hinges can be found on the sill, as the window will open from the top.
Spaces located on the window frame bottom and top will hold at least two glass panes together. These help to insulate the window.
