How are glass panels typically secured in place?

Glass panels are typically secured in place using glazier's points, clips, or adhesive due to the need for both stability and flexibility in the installation process. Glazier's points are small metal fasteners that secure the edges of glass panels within a frame, ensuring that the glass is held tightly in place to prevent movement or rattling. Clips can also be employed to add additional support, especially in larger installations. Adhesives, such as silicone or specialized glazing compounds, provide a seal that not only secures the glass but also contributes to waterproofing and insulation.

This method of securing glass panels is preferred because it accommodates the properties of glass, allowing for thermal expansion and contraction while maintaining a secure fit within the frame. The use of mechanical fasteners like nails or screws can lead to stress concentrations that may cause the glass to crack or break under certain conditions, while welding is not applicable to glass installations, as glass cannot be fused to metal frames in this way.
