What is the primary purpose of using a `mullion' in window design?
Show Hint
- For decoration
- To enhance ventilation
- To support the glass within the window frame
- To block sunlight
The Correct Option is C
Solution and Explanation
The primary function of a mullion is structural support, especially in large window openings.
It helps transfer the load of the glass and frame safely to the building structure.
Mullions also allow windows to be divided into smaller panes, improving strength and stability.
Decoration may be a secondary visual effect, but it is not the main purpose.
Ventilation and sunlight control are handled by operable sashes, louvers, or shading devices—not mullions. Therefore, the main purpose of a mullion is to support the glass within the window frame.
Final Answer: \(\boxed{\text{To support the glass within the window frame}}\)
