Types of drywall

Standard Drywall Standard Drywall or “White Board”- “Standard” drywall is what is most commonly used on drywall projects and comes in various sizes ranging from ¼” to 1” thick. The length is usually anywhere from 8’ or up to 16 feet long, and the width is usually 48”. As with most sheets of drywall the long sides or edges are typically tapered which make it easier to conceal drywall tape and joint compound during finishing. Moisture Resistant Drywall “Green Board” Drywall- Green board drywall has a green paper covering that makes it more resistant to moisture. This type of-of drywall is often used in bathroom, kitchen, and laundry room walls. Green Board is not 100% waterproof, so be aware that this product should not be used if it’s going to come in contact with water. “Blue Board” Drywall- Blue board drywall is another moisture resistant drywall that is used more for veneer plastering. It has higher water and mold resistance as well as unique absorption qualities. This type of drywall is most often used in bathrooms and other rooms with a lot of moisture. Paperless Drywall- Paperless drywall consists of gypsum in between fiberglass instead of paper. The fiberglass offers a much higher resistance to moisture, mold, and mildew than paper and is often used in areas of high humidity. Although it has higher moisture resistance, it should not be used in areas where the wall will have a direct exposure to water. Purple Drywall- If there are areas where water contact is likely, purple drywall is a great choice. Purple drywall offers the same advantages of regular drywall with a higher moisture and mold resistance. Cement Board- Cement board, is a popular choice for areas with high water contact such as bathroom and shower walls. It is a solid base for ceramic tile. It is made with cement that is reinforced with fibers making it a very strong board and solid base. Fire Resistant “Type X” Drywall- Type X drywall is commonly known as the “fire-resistant” drywall, is made with a gypsum core that is reinforced with special noncombustible glass fibers. It usually is ⅝” thick and has a 1 hour fire rating. “Type C” Drywall- “Type C” drywall is usually ½” or ⅝” thick and has a 2 thru 4-hour fire rating. More glass fibers are used to produce “Type C” than “Type X” drywall. “Eco-Friendly” Drywall Enviroboard- “Enviroboard”- consists of compressed fiber panels using ecologically safe materials that are usually waste fibers from newspaper or agriculture. EcoRock- “EcoRock” is composed of different recycled industrial byproducts such as slag, kiln dust and fly ash that are combined with filler and water which then binds the materials into a pourable paste. One of the major benefits of “EcoRock” is high resistance to mold and termites.
