A Glazing Bead (also called a glass bead or glazing strip) is a special strip that holds glass panels in place within windows, doors, or frames. Think of it like a picture frame that keeps a photo in place, but for glass in buildings. It's an important part of window installation because it not only keeps the glass secure but also helps prevent water leaks and drafts. Glaziers need to know how to work with different types of glazing beads, which can be made from materials like plastic, wood, or metal. This knowledge is essential for both installation and replacement work in residential and commercial buildings.
