What is the primary distinction between drywall and wetwall?

The primary distinction between drywall and wetwall lies in their material composition. Drywall is typically made from gypsum plaster sandwiched between two sheets of heavy paper, making it lightweight and easy to handle. It is designed for interior wall and ceiling applications in dry environments.

Wetwall, on the other hand, is specifically formulated to be water-resistant or waterproof. It usually consists of materials such as fiberglass, PVC, or treated cement board, making it suitable for areas exposed to moisture, such as bathrooms and kitchens. The different compositions cater to their respective environments, allowing wetwall to prevent mold growth and damage in high-humidity situations.

While other factors such as weight, size, installation methods, and cost may differ between the two materials, the essential difference fundamentally lies in what they are made of and the intended applications of each type. This distinction directly affects their performance and suitability for specific construction needs.
