Fire-retardant drywall is required by most building codes in certain areas of a home. Fire Retardant Drywallįire retardant drywall is designed to slow the spread of fire and give the occupants time to escape. In most instances, these panels will be faced with a special paper that also includes sodium pyrthione or other moldicide. Mold-resistant drywall panels include a chemical called sodium pyrthione, which prevents the growth of mold spores. Mold-resistant drywall is often green, but it can also be found in yellow, purple, or blue. Water-resistant drywall is commonly used anywhere moisture is present, like a bathroom, laundry room, or kitchen. Water-resistant drywall has a special element that helps it repel moisture, but the gypsum inside the panel is absorbent. Please note that water-resistant drywall is not waterproof. Water-resistant drywall is often green in color, but not always. Most professionals also use 4’ x 12’ standard panels horizontally on the walls for the same reason. The professionals will install ½” x 4’ x 12’ no sag panels on most of the ceilings, as this method results in the fewest joints. Most in-stock panels will be ½” thick, but ¼”, ⅜”, and ⅝” are also usually available. ![]() Standard drywall is the white or light gray version available in big box stores. Here we will briefly describe the most common drywall panels and what they are typically used for: Standard Drywall Some panels are treated with chemicals to reduce mold and mildew growth, while others are designed to be easier to install. ![]() Drywall panels are available in ¼”, ⅜”,½”, and ⅝” thicknesses, because most building codes require it to some degree. Most drywall panels are 4’ x 8’, but they also come in larger sizes, like 4’ x 12’, or even 4’ x 16’ as a special order. Why are some panels white or light gray, some are green, and some are blue? Why are some panels longer than others? Why are some thicker and some thinner? You’ve probably seen a building under construction and wondered why there are different colors of drywall panels in various locations. In modern construction, only the joints of the panels and the fasteners need to be skim coated with drywall compound. By eliminating the last skim coat of plaster, this method became the standard because it was easier, faster, and required less material. At the time, the paper used for the panel construction was not directly paintable, as it would simply absorb the paint and wrinkle.Įventually, it was discovered that changing the materials and manufacture of the panel allowed it to be painted directly. Using Sacketboard sped up the process, but the material still needed a skim coat of plaster to accept paint. ![]() Sacketboard was still made from mostly plaster, so it was installed in place of lathe strips, and another layer of plaster was applied on top. Installing wooden lathe strips was very time-consuming, so a solution was needed. The panels were made from a combination of plaster and paper and designed to ease the burden of installing wood lathe strips on every surface that would need plaster. source: What is Drywall?ĭrywall really began as a product called Sacketboard, which was the first product to place plaster between two panels to form a sheet. While we’re on the subject, let’s answer a few more commonly asked questions about drywall. However, there are several companies that manufacture drywall panels, so not all drywall is sheetrock. To clarify, “sheetrock” is a brand name of the drywall panel (made from gypsum and paper) most of us have in our homes.
