Plasterboard and drywall are terms that are often used interchangeably, but they essentially refer to the same thing. Both are commonly used as wall and ceiling coverings in construction, and both are made from gypsum as the core material. However, depending on the region, people may refer to them differently. Understanding this terminology is crucial for professionals in the construction industry and homeowners alike. This article will explore six key things you didn’t know about plasterboard and drywall, shedding light on their unique characteristics and applications.
The definition and composition of plasterboard and drywall
Plasterboard, also known as gypsum board or gypsum panel, is a building material used in the construction of interior walls and ceilings. It is made of a core of gypsum plaster sandwiched between two sheets of heavy paper. The gypsum core is what gives the plasterboard its fire-resistant properties. The paper facing is typically made from recycled paper, making plasterboard an environmentally friendly option.
Drywall is simply another name for plasterboard, especially common in the United States and Canada. In other regions, such as the UK and Australia, the term plasterboard is more commonly used. Both refer to the same gypsum-based product. Cement board and fiberglass board are different products entirely and are not classified as drywall. Therefore, drywall cannot be made from cement or fiberglass. Drywall always refers specifically to gypsum-based boards.
The history and evolution of plasterboard and drywall
The use of plasterboard and drywall in construction dates back to the early 20th century. Plasterboard was first patented in 1888 by Augustine Sackett and Fredrick L. Angell. However, it wasn’t until the 1920s that plasterboard became widely used in the United States. The invention of the drywall nail gun in the 1950s revolutionized the construction industry, making it easier and faster to install drywall.
The evolution of plasterboard and drywall has been driven by advances in technology and changes in building codes. Today, there are many different types of plasterboard available, each with its own unique properties and uses. For example, mold-resistant plasterboard is now commonly used in bathrooms and kitchens, while soundproof plasterboard is used in home theaters and music studios.
The different types of plasterboard and drywall
There are several different types of plasterboard available on the market today. Standard plasterboard is the most commonly used type and is suitable for most interior wall and ceiling applications. It is made from gypsum plaster and paper and is available in different thicknesses.
Fire-resistant plasterboard, also known as Type X drywall, is used in areas where fire safety is a concern. It is made from gypsum plaster with added fire-resistant materials and is thicker than standard plasterboard.
Soundproof plasterboard is used to reduce noise transmission between rooms. It is made from gypsum plaster with added soundproofing materials and is thicker than standard plasterboard.
Mold-resistant plasterboard is used in areas with high humidity, such as bathrooms and kitchens. It is made from gypsum plaster with added mold-resistant materials and is available in different thicknesses.
Cement board and fiberglass board, although used in building applications, are separate categories of materials and are not considered drywall or plasterboard. They are typically used in areas that require higher moisture resistance, such as exterior walls or tile backings.
The installation process for plasterboard and drywall
The installation process for plasterboard and drywall is identical because they are the same product under different names. Typically, plasterboard is installed using screws or nails fixed to the timber or metal framing structure.
When installing plasterboard, it is important to ensure that the edges are flush with the framing members and that the screws or nails are not overdriven.
Proper installation also requires staggering the seams between sheets to avoid creating weak points in the wall. A drywall saw is often used to cut the boards to fit the space accurately. Care should always be taken not to overtighten screws, as this can damage the surface and lead to cracking.
The benefits of using plasterboard and drywall
There are several benefits to using plasterboard and drywall in construction. They are both easy to install, cost-effective, and can be painted or finished to match any decor.
Plasterboard and drywall are fire-resistant due to the gypsum core, making them a safe choice for interior walls and ceilings. Special variants, such as soundproof or moisture-resistant boards, provide added performance in specific environments like home theaters, bathrooms, or kitchens.
In addition, plasterboard and drywall are environmentally friendly options, as they often incorporate recycled materials and can themselves be recycled at the end of their life cycle.
Conclusion
Understanding the correct definition of plasterboard and drywall is crucial for professionals in the construction industry and homeowners alike. Both terms refer to gypsum board and are used as wall and ceiling coverings with similar properties and applications. Cement board and fiberglass board are separate products and should not be confused with drywall.
By understanding these distinctions and the different types of plasterboard available, you can make an informed decision about which material is best for your project. Whether you are building a new home, renovating an old one, or simply looking to update your walls and ceilings, plasterboard or drywall offers a range of benefits that make it a popular and reliable choice.
