Dry wall is considered:

Dry wall is considered:

• A. Combustible.
• B. Non-combustible.
• C. Fire-resistive.
• D. A strong structural material.

Answer: (C)

Drywall is used as a fire-resistive barrier in walls and ceilings. The gypsum core contains water, and when exposed to heat this water is released, which slows heat transfer and flame spread. In fire-rated assemblies, drywall is installed in specific thicknesses and joined with appropriate finishes to achieve a stated fire-resistance rating, helping protect structural members for a defined period. Its main purpose is to resist fire and maintain compartment integrity, not to provide primary structural strength. So, in the context of fire protection, drywall is described as fire-resistive because of its role in delaying heat transfer within rated assemblies.
