What Are The Different Parts of a Window?

There are many different parts of a window, and you’ll find that some parts differ from window type to window type. This is because window anatomy is not the same for all window types. In this guide, we’ll review the different parts of several windows, and point out those parts that can be found on all window types.

What Does A Window Anatomy Consist Of?

Every window features a framework; this is the part that surrounds the entire window system. The framework consists of a head, jambs, and a sill. The head is the main horizontal piece that makes up the top of the window frame. The jambs are the vertical side pieces that make up the left and right portions of the frame. The sill is the horizontal piece that makes up the bottom part of the frame. Of course, all windows also feature glass panes.

Understanding the Various Parts Involved With a Window

While these parts are common on all window anatomy, certain individual types of windows have parts that are unique to that model. Here are a few popular window types, and the parts they contain.

Double-Hung Window: Hardware and Interior Parts

A double-hung window contains probably the most parts of any window type. It has a sash, which is the moveable part of the window that opens and closes. Each sash consists of its own vertical and horizontal frame. The check rail is the part where the bottom part of the upper sash and the upper part of the lower sash come in contact in the middle of the entire window system. The rails are the upper and lower horizontal pieces of a sash.

This type of window also has a lift, which is what the handle used to open and close the window is called; and a sash lock, which is a locking mechanism that secures the window and helps prevent it from rattling. Meanwhile, the balance is a spring-loaded mechanical device that’s hidden within the window’s frame; this piece counterbalances the weight of the sash being opened.

Casement Window: Hardware and Interior Parts

Casement windows open to the left or right, using a hand crank called an operator. When the window is closed, it is locked shut with a lock handle that’s installed on the jamb. The casing is the decorative molding around the window. It covers the space between the frame or jamb and the wall, and is typically made from vinyl.

Casement windows also have a piece of weather-stripping material that covers the joint between the frame and the sash, which serves to help insulate the window and prevent air or water from penetrating into the home. All Thompson Creek windows have weather-stripping to help prevent the elements from entering your home.

Stationary Window: Hardware and Parts

A stationary window doesn’t open, so it has minimal parts. But it does have certain parts that other types of windows do not typically contain. For instance, stationary windows feature a fixed panel of glass. The window features vertical and horizontal pieces that when combined form a mullion.

In some stationary windows, decorative pieces are used to divide a large piece of glass into what looks like several smaller windows. This decorative piece is what is known as grids.
