What is the primary function of a glazing chart?

A glazing chart primarily serves as a reference tool that outlines the various types of glass materials available, their associated thicknesses, and the appropriate applications for each type. This makes it essential for ensuring that the selected glass meets the specific requirements of a project, such as energy efficiency, safety, and structural integrity. By providing detailed information about different glass options, a glazing chart enables glaziers to make informed decisions that align with building codes and standards, ensuring that the glass will perform adequately for the desired application.

Other options, such as designing window frames or calculating installation costs, involve different areas of expertise that are not the main focus of a glazing chart. While selection of hardware may be related to the installation process, it does not directly pertain to the glass types and thicknesses that a glazing chart addresses. Thus, the primary function of a glazing chart clearly centers on identifying the right glass type and thickness for various applications.
