Discovering the history and types of drywall can be fascinating, especially when you consider the evolution of construction methods over time. If you're a homeowner, architect, or history enthusiast, let's delve into the world of old drywall types, accompanied by captivating pictures.
Drywall, also known as wallboard or plasterboard, has significantly impacted construction since its introduction in the early 20th century. It has replaced traditional lath and plaster methods, revolutionizing the industry with its efficiency and accessibility. But before we explore the various old drywall types, let's understand the context behind their inception and popularity.
Early Drywall Types
In the dawn of the 20th century, innovative construction materials were being developed to streamline the building process. Drywall was one such material that sought to replace the labor-intensive, time-consuming lath and plaster method. The first recorded use of drywall was in 1916, when the United States Gypsum Company (USG) introduced a product called "Squares" - the precursor to modern drywall.
Squares were large, heavy, and brittle, making them difficult to work with and install. Despite these challenges, they paved the way for future drywall types and marked the beginning of a new era in construction. Soon after, other companies began to develop their versions of drywall, leading to the emergence of various types.
horsehair Plaster
Before drywall, horsehair plaster was a common wall finishing material. It was a mixture of lime, sand, and horsehair, applied in multiple thin layers to create a smooth, durable finish. While horsehair plaster was popular for its durability and aesthetic appeal, its labor-intensive application contributed to its eventual decline in popularity.
Pictures of horsehair plaster reveal a textured, semi-glossy surface that often develops distinctive patterns over time, adding to its character and charm. Although less common today, some older homes still feature horsehair plaster, considered a status symbol in their era due to the skill and craftsmanship required for installation.
Particle Board and Oriented Strand Board (OSB)
Particle board and OSB are engineered wood products composed of wood particles or strands glued together under high pressure. Introduced in the mid-20th century, these drywall alternatives offered lower costs and better strength-to-weight ratios than traditional gypsum drywall. However, their susceptibility to moisture damage and increased flame spread potential limited their widespread adoption.

Classic Drywall Types
As drywall technology advanced, manufacturers refined their products, leading to a range of classic drywall types still in use today. These improvements focused on size, shape, and composition, catering to various construction needs and preferences.
By mid-century, drywall had become the industry standard, thanks to these innovative advancements. Its lightweight nature, ease of installation, and superior fire resistance made it an ideal material for residential and commercial constructions alike.
Standard Drywall
Standard drywall, also known as gypsum board, consists of a layer of gypsum plaster supported by two thick paper faces. It comes in various thicknesses, typically ranging from 1/4" to 1" (6mm to 25mm), with 1/2" (12mm) being the most common. Standard drywall is suitable for most interior wall and ceiling applications.

Fire-resistant Drywall
Fire-resistant or Type X drywall contains a proprietary gypsum mixture that provides enhanced fire protection. It is often used in firewalls, party walls, and other critical locations where additional fire resistance is required. Type X drywall is typically thicker than standard drywall and may have green markings to indicate its fire-resistant properties.
Pictures of Type X drywall illustrate its strategic use in construction, emphasizing the importance of fire safety in building design. Its integration into various architectural styles demonstrates the adaptability of drywall in meeting-code-compliant construction standards without compromising aesthetics.
Moisture-resistant Drywall
Moisture-resistant or greenboard drywall features a proprietary gypsum core and paper faces designed to withstand moisture, making it ideal for humid environments, such as bathrooms, laundry rooms, and basements. Greenboard drywall is typicallyREENboard is an excellent choice for moisture-prone areas, offering enhanced resistance without compromising ease of installation or appearance.

In conclusion, exploring old drywall types reveals a rich history of innovation and adaptation in the construction industry. From the early days of brittle plaques to modern standard, fire-resistant, and moisture-resistant options, drywall has evolved significantly to meet the diverse needs of architects, builders, and homeowners. As technology continues to advance, it's fascinating to consider what the future holds for this indispensable material.
So, the next time you're tackling a home improvement project or appreciating the architectural charm of an older home, take a moment to appreciate the rich history and evolution of old drywall types. Perhaps you'll even uncover a hidden gem, inspiring your next renovation adventure.
