Which statement is accurate regarding drywall?

1. Drywall can only be installed vertically and not horizontally.

2. Drywall was once widely used in residential construction, but now has been largely replaced by plaster.

3. Gypsum is typically used in the production of pre-manufactured drywall.

4. Drywall is installed to provide structural integrity in a residential building rather than for decorative reasons, such as concealing pipes and wires.

5. Drywall is always fire-resistant.

6. Drywall is primarily used for exterior walls.

The correct answer is: Gypsum is typically used in the production of pre-manufactured drywall.

The correct statement regarding drywall is that gypsum is typically used in the production of pre-manufactured drywall. Gypsum, a soft sulfate mineral, is a key ingredient in the production of drywall due to its fire-resistant and soundproofing properties. By adding water to dry gypsum powder and sandwiching it between paper layers, manufacturers create the drywall sheets commonly used in construction. This process provides a durable and versatile building material that is easy to install and finish. The other options are not accurate: - Option A is incorrect as drywall can be installed both vertically and horizontally, depending on the design and construction requirements. - Option B is incorrect as drywall continues to be widely used in residential and commercial construction due to its efficiency and cost-effectiveness compared to plaster. - Option D is incorrect as drywall is commonly used for both structural support and aesthetic purposes, such as concealing pipes and wires. - Option E is incorrect as while drywall can have fire-resistant properties, not all types are guaranteed to be fire-resistant. - Option F is incorrect as drywall is typically used for interior walls, ceilings, and partitions, rather than for exterior walls.
