We use windows in our everyday lives, but rarely do we think about all of the parts that make up a window. You may have heard of the window pane and window sill, but many other components are a part of the finished product. All the lingo and the terms can get confusing, so Springfield Glass Company is here to help.
In today’s glass window glossary, we outline some key terms and identify the major parts of windows. The next time you’re out shopping for windows, this glossary can serve as your guide.
The Parts of a Window
Windows come in many shapes and sizes, but most of them are made of the same parts. Read on to learn the details.
The window frame consists of the sill, head, and jamb. It’s usually made of wood or vinyl. The sill is the lowest part of the frame, while the head is the highest. The jambs are the vertical sides of the frame.
