A Spacer Bar (also known as a window spacer or glazing spacer) is an important component in double or triple-glazed windows. It's the strip that goes around the edge between glass panes, keeping them apart at the correct distance. This creates an insulating gap that helps windows be more energy efficient. Think of it like a frame inside the window that you can see when you look at the edge of the glass. People working with these need to know how to properly measure, cut, and install them to ensure windows work effectively.
