Depending on where you live, the building code may require that you use moisture-resistant drywall. Moisture-resistant drywall is also known as the green board. It is suitable for areas of a room that are exposed to moisture.

The price of drywall ranges from $12 – $20. Moisture-resistant drywall costs $14 – $18 per panel. You will pay $0.40 – $0.50 per foot to install it. It is more expensive than standard drywall. While it is moisture-resistant, it is not fully waterproof.

There are many types of drywall that you can install in different parts of the home. You may also need specialized drywall depending on the weather in your region.

Here are some of the notable features of the green board.

Moisture resistant

The most prominent feature of green board drywall is its moisture resistance. It means that this type of drywall handles moisture better than standard drywall. Hence, it is installed in areas with high moisture levels.

It cannot be installed outdoors or in showers since it is not waterproof.

Thicker than standard drywall

Green board is thicker than regular drywall. The extra thickness provides its moisture resistance capabilities.

The thickness on the green board comes from wax infused in the material used to make the drywall panel.

However, exposure to water makes it weak and it tears down easily. Therefore, it should be installed in areas of moisture and not water.

Not fire resistant

Moisture-resistant drywall is not fire resistant. If the building code in your area requires you to install fire-resistant drywall, the green board will be useless. It may be the same thickness as fireproof drywall, but it is not fire resistant.

Fireproof drywall slows down the spread of fire. However, wax that is used in moisture-resistant drywall will melt when exposed to fire or heat. Consequently, the fire will spread fast if you use moisture-resistant drywall.


Green board lasts longer than standard drywall. Moisture-resistant drywall is made with more gypsum than standard drywall.

In addition, the layer of paper ensures that the drywall has superior moisture handling capabilities and protects it from environmental factors that may reduce its lifespan.

Uses of moisture-resistant drywall

As its name suggests, moisture-resistant drywall handles moistness better than standard drywall.

As a result, it can be installed in areas of the house that have more than ordinary moisture levels.

Green board can be installed in the following areas:

  • Bathrooms
  • Sink
  • Laundry rooms
  • Basements
  • If you are building your home in a humid region
  • Utility rooms
  • Crawl spaces

Moisture-resistant drywall, however, is not waterproof. Consequently, it should not be installed in areas that have water such as

  • Saunas
  • Steam rooms and
  • Indoor pools.

Benefits of moisture-resistant drywall

  • Easy to use and install.
  • Eco-friendly.
  • Good for insulation
  • Numerous design options.
  • Balance humidity in rooms.
  • Good for sound insulation
  • Lightweight enough to install in ceilings, walls, and other areas.

Factors that determine the cost of drywall installation

Type of drywall you use

There are many types of drywall you can install in your home. Each type of drywall has its purpose and price.

Standard drywall is the most common gypsum board used to finish homes. Depending on the building code, you may require waterproof, fireproof, and soundproof gypsum. Standard gypsum does not possess these capabilities.

Therefore, you will pay more to get these specialized drywall types.
