A versatile building material called drywall is used to build or cover walls and ceilings. It comes in a wide range of materials and constructions, including mold-resistant, plasterboard, and VOC-absorbing. If you're on the lookout for quality drywall, finding a reliable sheetrock supplier can make all the difference.

| Understanding the Different Types of Sheetrock and How They’re Used |
Most homes had plaster and lath for their walls before World War I. After the war, drywall was developed to fill a market for a quicker way to finish walls. Today, it serves as the main interior wall finish material.
What is drywall?
The framing on walls and ceilings is covered with drywall, a type of building material. Gypsum, a mineral that occurs naturally and is widely available, is used in its construction, making it an environmentally friendly material. A slurry made of gypsum and other components is sandwiched between two sheets of paper and dried. The kind of drywall depends on the thickness and type of paper as well as the slurry's chemical composition.
Wallboard, sheetrock, and gypsum board are further names for drywall. (The U.S. Gypsum Corporation uses the latter as a brand name.)
Interior walls and ceilings of homes and businesses are soundproofed and fire-resistant, thanks to drywall. It is fastened to the framing with screws, the gaps between the drywall panels are taped to conceal them, and then mud is used to fill in the gaps and cover the screw holes. Depending on the desired finish, the wall is either painted or textured after the mud dries and is sanded to a fine finish.
Drywall thicknesses
Different thicknesses of drywall are utilized in various applications. In order to improve soundproofing or fire protection, more layers of drywall might be used.
The thinnest wallboard, which is typically used on curved walls, is 14 inches. Its thinness makes it more flexible, particularly when damp. The drywall is finished like ordinary drywall once it has dried.
Twelve inches is the typical drywall thickness. The majority of the walls in both residential and commercial construction employ this. It offers fire protection for thirty minutes. In rooms or places where extra protection is required, multiple layers are frequently used.
5/8-inch drywall can be used to increase fire resistance or soundproofing. It has a 60-minute fire resistance rating and is frequently put in layers for added security.
6 Common types of drywall.
There are various drywall types, which are typically distinguished by the color of the paper that surrounds the drywall. Different paper types and adding chemicals to the slurry cause the variances.
Mold-resistant drywall-
Green board, also known as mold-resistant drywall, has a paper backing that is thicker than conventional drywall and is wax-coated for increased moisture resistance. Additionally, it has a non-organic fiberglass mesh called "paperless drywall" that removes the nutrients mold needs to grow.
The most popular places to utilize mold-resistant drywall are bathrooms, kitchens, laundry rooms, and a tile backer. There is also mold-resistant mud available. Keep in mind that mold-resistant drywall is not the same as moisture-resistant drywall.
Regular drywall-
The most popular type of drywall used for walls and ceilings in residential and commercial construction is regular drywall, sometimes known as whiteboard. 12 inches is the most typical thickness for residential applications.
The most typical drywall sheet size is 4' x 8', but for high ceilings, it's also available in lengths of up to 16'. To make the sheets easier to handle and for modest repairs, home improvement businesses sell drywall in 2' by 2' sizes.
Plasterboard-
Similar to how lath is used in lath and plaster walls, plasterboard, also known as blue board, serves as the foundation for plaster applications. A thin coating of plaster must be applied over the whole surface of the plasterboard.
Because the face paper absorbs moisture, the plaster finish layer adheres to the drywall more effectively. Older homes utilize it to create the appearance of plaster and lath.
Soundproof drywall-
While every drywall has some soundproofing properties, soundproof drywall goes above and beyond conventional drywall's sound transmission class (STC) by adding more wood fiber, gypsum, and polymers. STC is a rating that gauges how much noise a material can block, much like the Richter scale.
When more soundproofing is needed, such as between living areas and common walls, soundproof drywall is employed. It can be more challenging to deal with because it is denser than conventional drywall.
Fire-resistant drywall-
Around potentially flammable equipment in garages and basements, specialized fire-resistant drywall is utilized. It contains fiberglass, which retards the spread of fire and burns more slowly than standard gypsum.
Type X and Type C are the two different varieties of fire-resistant drywall. Type X is 5/8" thick and offers up to an hour of fire protection. If necessary, it can be applied in several layers to offer more protection. Similar to Type X, Type C does not shrink when burned. In order to prevent collapse during a fire, it is usually utilized in ceilings.
VOC-absorbing drywall-
VOC-absorbing drywall, a relatively recent invention, traps chemicals and other volatile organic compounds inside the drywall, rendering them inert. These chemicals are found in both the cleaning supplies we use on a daily basis and other building materials. The drywall continues to function for up to 75 years after being painted or covered with a light wall covering.
Conclusion-
Navigating the diverse landscape of sheetrock types and their applications is crucial for any construction project. With a clearer understanding of these variations, the next step is finding a reliable sheetrock supplier.
