If you’re going to replace your windows, you should familiarize yourself with the basics first: how windows work and what different components are called. This way, you can speak intelligently with an expert when it comes time to pick the types of windows you want for your home or business. Learn the lingo so you can communicate effectively and find exactly what you’re looking for!
SASH
This is the framework holding the glass in place and includes the rails and stiles.
Rail
Stile
FRAME
The frame is made up of the head, jambs, and the sill. This is what the window sits in; it holds the sash that frames the glass portion of the window. It's the shell that creates the opening inside the wall.
Jamb
The jambs are the vertical parts of the window frame.
Head
The head is the horizontal component making up the top part of the window frame.
Sill/Stool
The sill and stool are two names for the same part of the window. It's the inside portion near the bottom of the window that protrudes into the building's interior.
APRON
The apron is the board underneath the sill that attaches to the wall.
GLAZING
Glazing is the actual glass inside the window frame. Have you ever hear of double or triple glazing? This just means the window is composed of two or three sheets of glass to make the surface thicker and increase its energy efficiency.
MUNTIN/GRILLE
Grilles (or muntins) are the bars that make up a grid-like structure dividing the glass into smaller panes. Sometimes grilles are placed over one large pane of glass to divide it up, while other times they are used to actually hold several separate pieces of glass in place.
CASING
OPERATOR
This is the crank or handle you use to open and close casement and awning windows.
SCISSOR/EXTENSION ARM
The scissor arm is what extends or contracts as you open or close the window with the crank of a handle.
LOCK/LATCH
On a double hung window, the latch is located where two rails meet; on a casement window, it’s located on the stile; and on an awning window, it’s on the rail at the bottom of the sash. The latch is what locks the window and helps it seal tightly when it’s closed.
SCREEN
Screens can be made up of metal, fiberglass, or plastic that is woven to create a mesh that allows for airflow and ventilation when the window is open. It lets air flow through while keeping insects outdoors.
Screen Strike
This is the lock that holds the screen in place. Unlatch it to remove the screen from the window opening.
Those are the main components of a window. Now that you know the anatomy, you can shop for your new windows with confidence!
