Which of the following cannot be used to anchor windows and glass doors?

1. Frame

2. Frame clip

3. Flange opening

4. Substrate

The correct answer is: Substrate

The reasoning behind identifying "substrate" as the choice that cannot be used to anchor windows and glass doors involves understanding the specific roles of each component in the construction process. When anchoring windows and glass doors, it's essential to use elements specifically designed to provide structural stability and secure connection points. The frame and frame clip are integral parts of the window and door assembly, designed to hold the glass in place and ensure that the overall structure is securely affixed to the building envelope. They provide the necessary support and alignment for proper installation. A flange opening is typically a part of the frame that allows for connection to the building structure, facilitating attachment and enhancing stability. These components are specifically engineered for anchoring purposes, ensuring that the windows and doors are safely and correctly installed. In contrast, a substrate is generally understood as a base or underlying material upon which other materials are applied or constructed—such as concrete, wood, or drywall. While it offers support to the structure, it does not serve as an anchoring mechanism for windows and glass doors. Instead, it acts as a foundation and is involved in supporting various building systems rather than securing windows and doors directly. Thus, a substrate cannot be used specifically to anchor windows and glass doors, distinguishing it from
