Drywall is a specific type of sheeting material made of gypsum sandwiched between paper. Drywall is also referred to as wallboard, plasterboard, or gypsum board. Well over 60 years ago drywall replaced plastering. Drywall technique is less expensive and easier to attach. Plastering is heavy and can lose it’s holding strength.

Types of Drywall

Regular

The most typical drywall used in standard interior applications is 1/2″ drywall in 4′ x 8′ panels.

Moisture-resistant

Also called green-board, due to its color, this has the same mineral core as drywall, but with a water-resistant facing. It is typically used in wet areas such as around a bathtub. This is not water-resistant

Fire-resistant

Has a core with additives that contain fires well. Fire rating for panels is measured in time. Due to its tougher core, it can be more difficult to cut.

Flexible

When you have an arch or a curved wall, 1/4″ flexible drywall is the best type to choose. It has a stronger paper face than regular 1/4″ drywall and is more resistant to cracking.

Cement board

Sometimes called concrete backer-board or the brand names of Durock and Wonder Board, it is used as a surface for ceramic tiles. It is not a gypsumbased product, as it has a solid concrete core.

 Gp’s Denshield

This is a mold-resistant board used for tiling. It has a glass face and an acrylic coating that prevents moisture from entering the wall cavity.
