Components Of A Window

When you look at a window you may not think that there is much to it. In fact, there are quite a few components to your replacement windows that you may overlook. Each aspect is meticulously integrated to create an effortlessly operated window. Certain parts to your window improve curb appeal, while others make the home more energy efficient. Some pieces are only applicable to double hung windows while others only apply to bay or casement windows. Either way, in this article we will go over the terms for some of the most common parts of the window and how they operate.

Parts Of A Double Hung Window

Frame

The frame surrounds and supports the entire window system. The frame is made up of the head, the jamb, and the sill.

Head

The main horizontal part that forms the top of the window frame.

Jambs

The main vertical parts that form the sides of the window frame.

Sill

Sometimes referred to as the “stool” of the window, the sill is the main horizontal part that forms the bottom of the window frame.

Glass

Also referred to as the window pane, the glass is the framed sheet of glass within the window frame.

Sash

The moveable part of the window that holds the glass. In a double-hung window the sash moves up and down. On a slider window the sash moves horizontally. On awning or casement windows the the sash moves outward from a crank mechanism.

Sash Lock

The sash lock is a locking mechanism that engages with the sash to reduce rattling as well as keep the home secured from unwanted guests.

Gas Fill

The gas fill is the element that is injected between the window panes to insulate the home. There are a couple options that are common in the replacement window industry, the two most common being Argon and Krypton. Both are more dense than air so they form a protective barrier between air inside your home and the harsh outside elements. Krypton insulates your home about 40% more than Argon, because Krypton is more dense. Overall this makes the interior of your home less influenced by the temperatures outside the home, saving you money on your energy bill.

Overall, knowing these components and how they work will make it easier for you to make an educated decision on your replacement windows. It also doesn’t hurt to schedule a consultation and weigh in the opinion of an expert!
