As any do-it-yourself drywaller discovers, there are many of various kinds of drywall. Go to your neighborhood do-it-yourself store or lumberyard and you’ll find that what you thought was “pretty standard” is actually only the tip of the iceberg.
Don’t let all those different types of drywall overwhelm you! You can find several types of drywall compositions, thicknesses, and sizes for different applications and uses. How do you know what you should purchase? Below is information on the most common types of drywall available to help you create the right decision.
This is the most common type of drywall (white paper front) and can be used for the majority of do-it-yourself and new home interior construction. Before beginning a project check with local building codes to ensure they do not specify that one type of drywall can be used in construction.
Standard drywall is normally sold in either 4’x8′ sheets, or 4’x12′ sheets. Drywall Repair San DIego Which of the sizes you use depends upon the size of the area in which you’re installing drywall, the number of people carrying it out, and the simple access (in a basement, for instance, it may be impossible to turn a large part with a 12′ sheet). 4’x12′ sheets are problematic for a single person to utilize.
My recommendation is by using 4’x12′ sheets whenever you can. It reduces the number of cuts that need to be made as well as the amount of joints that will have to be finished.
Standard drywall can be sold in a number of widths – 1/4″, 3/8″, 1/2″, and 5/8″. 1/2″ is the standard width of drywall, suitable for most interior construction on walls and ceilings. 1/2″ drywall is considered acceptable by most local building codes.
1/4″ drywall is called flex-board and often useful for curved surfaces. It is somewhat fragile rather than highly suggested for the amateur drywall installer.
5/8″ drywall is heavier-duty drywall, suitable for use in commercial settings, high traffic areas, or where some excess insulation or noise control is necessary. In some areas, 5/8″ drywall is required by local codes.
Moisture-Resistant Drywall (Green Board)
Moisture-resistant drywall is also known as Green Board in mention of the water-resistant green paper used outside the gypsum. Moisture-resistant drywall is a common type of drywall useful for high-moisture areas such as for example bathrooms & kitchens. There is absolutely no difference from standard drywall except that the paper backing used has a much higher moisture resistance than standard drywall.
Green board is highly suggested for use in bathrooms, damp basements, and may be used in kitchens (especially around stoves and sinks). You should note that green board is not fire-resistant, nor waterproof, but resistant to damp conditions.
The final common kind of drywall is Fire Resistant, or FR, drywall. FR drywall is available mostly in the 5/8″ thick variety. Special fibers and other fire-resistant materials are added to the gypsum core to create more fire-protection than standard drywall.
Building codes in many areas require the use of Fire Resistant drywall for several applications, including:
Walls separating an attached garage from a living space.
Walls and Ceilings in attached apartments or condos.
Enclosed rooms enclosing furnaces, water heaters, or other fire hazards.
There are many other types of drywall as well, including soundproof drywall, paperless drywall, among others, however they are less common and so I won’t cover them here. The very best of luck on your own drywall project. Visit “HOW EXACTLY TO Drywall” for more drywall installation instructions.
