If you don’t work in the window industry, you might find the terminology a bit confusing. There are names for window parts that you don’t often hear in everyday conversation. This can make for a “communications gap” when homeowners talk with window sellers and installers.
To help bridge that gap, we present our Window Parts Glossary for our two most popular types: Double Hung and Casement windows. It should come in handy if you ever need to purchase parts or order replacement windows.
