Red Seal Glazier Practice Exam

Spandrel glass refers specifically to opaque glass that is primarily used to conceal structural elements in a building, such as floors and beams, in order to create a unified and aesthetically pleasing appearance. This type of glass is often found in curtain walls and is placed between window openings to provide a seamless transition between different sections of a building. The opaque nature of spandrel glass helps improve the overall visual design by hiding less attractive structural components while maintaining a sleek exterior.

The other options don't accurately describe spandrel glass. Skylight glass serves a different purpose by allowing natural light to enter a space. Glass designed for thermal efficiency focuses on energy performance rather than the aesthetic concealment of structural elements. Decorative glass for storefronts aims to enhance visibility and appeal rather than provide concealment. Thus, understanding spandrel glass in the context of its function is crucial for anyone involved in glazier work or building design.
