What are glazing beads used for?

1. To enhance the decorative aspect of the window

2. To hold the glass in place

3. To provide insulation

4. To secure the frame to the structure

The correct answer is: To hold the glass in place

Glazing beads serve a fundamental role in window construction, primarily focused on securing the glass within the frame. These narrow strips are typically installed around the perimeter of the glass in a window unit, effectively holding the glass in place and preventing it from shifting or falling out. The design of glazing beads not only ensures stability but also facilitates the easy replacement of glass if necessary, as they can be removed without damaging the frame or the glass itself. While enhancing decorative aspects, providing insulation, or securing the frame are important considerations in window design, the specific function of glazing beads is closely tied to maintaining the integrity and positioning of the glass, making their primary purpose clear.
