What is the purpose of using additional fasteners in ceiling drywall installations?

To enhance aesthetics
To prevent sagging due to weight
To improve sound insulation
To facilitate quicker installation

The correct answer is: To prevent sagging due to weight

Using additional fasteners in ceiling drywall installations primarily serves to prevent sagging due to weight. Ceiling drywall is typically subjected to gravity, which can cause it to bow or sag over time, especially if it is not adequately supported. This is particularly relevant in situations where the drywall is installed in large sheets or in areas where the ceiling might experience moisture, adding to the overall weight. By increasing the number of fasteners, you ensure that the drywall is securely attached to the framing or ceiling joists, distributing the weight more evenly and providing greater structural integrity. This approach helps maintain a flat and even ceiling surface, which is crucial for both visual appeal and the proper installation of subsequent finishing materials. While enhancing aesthetics, improving sound insulation, and facilitating quicker installation are important aspects of drywall work, they do not directly address the fundamental need for support against sagging that can compromise the durability and performance of the ceiling over time.
