Plasterboard also known as drywall, gyprock, or gypsum board is one of the most essential components of modern construction. Yet, despite its widespread use, it’s often viewed as nothing more than a smooth surface behind walls and ceilings. In reality, this versatile material has a rich story involving history, science, and sustainability.
In this article, we’ll uncover five lesser-known facts about plasterboard that might just change the way you see it. We’ll also introduce practical accessories and solutions offered by Proaks that can help you maximize the efficiency and performance of your plasterboard systems.

Plasterboard Has Been Around for Over a Century
If you think plasterboard is a recent invention, you’d be surprised to learn that it dates back to the mid-1800s. It was first manufactured in the UK and made its way to Australia in the 1890s, where it was used in a small cottage in North Sydney. However, it didn’t gain widespread popularity until the 1960s.
Why Did It Take So Long?
Early on, builders were skeptical. The idea that two sheets of paper enclosing a gypsum core could provide a durable surface seemed questionable. But once tradesmen saw how fast, clean, and easy it was to install, they were convinced.
Today, plasterboard is a standard material used in homes, offices, and commercial buildings worldwide.
Plasterboard Offers Impressive Fire Resistance
At first glance, a material made of paper and powdered rock doesn’t exactly scream “fireproof.” But plasterboard is surprisingly resilient when exposed to fire.
How Does It Work?
The core of plasterboard contains calcium sulfate dihydrate (CaSO₄·2H₂O) a naturally non-combustible mineral. What makes it special is the crystallized water within its structure. When heat is applied, this water vaporizes, helping to absorb heat almost like a built-in fire shield. This slows down combustion and helps prevent the spread of flames.
What Is FRL?
In Australia, the Building Code of Australia (BCA) measures fire resistance using the FRL rating Fire Resistance Level. It includes three key metrics:
- Structural Adequacy – How long it retains load-bearing strength
- Integrity – Its resistance to flame and gas penetration
- Insulation – How well it limits temperature rise on the unexposed side
Proaks offers premium access panels that integrate seamlessly with fire-rated plasterboard systems, helping maintain both function and safety in critical areas.
The Gypsum Inside Is a Wonder of Nature
Gypsum, the core ingredient of plasterboard, is far more than just construction filler it’s a natural marvel with countless uses.
What Exactly Is Gypsum?
Gypsum is a sedimentary mineral found around the world. After mining, it is heated to remove about 75% of its water, resulting in a fine white powder commonly known as Plaster of Paris. When mixed with water, it becomes moldable and then hardens into a solid shape as it dries.
Where Else Is It Used?
You might be surprised to know gypsum appears in:
- Toothpaste
- Shampoo
- Sculpture and pottery
- Orthopedic casts
- Special effects snow in early Hollywood films
Its ability to be shaped, set, and solidify makes it a favorite in both construction and the arts.
It’s Known by Many Names Around the World
While the material remains essentially the same, plasterboard is called by different names in different countries:
- Drywall (USA)
- Gyprock (Australia)
- Sheetrock (Popular brand name)
- Wallboard
- Gib Board (New Zealand)
Why So Many Names?
In New Zealand, for example, the name “Gibraltar Board” was introduced in 1931 by Winestone Wallboard Company, inspired by the Rock of Gibraltar in the UK. The name stuck and was eventually shortened to Gib Board, which is still widely used today.
Regardless of the name, the core features of plasterboard remain the same lightweight, versatile, and reliable.
Plasterboard Is Fully Recyclable
Among eco-conscious building materials, plasterboard is a top contender due to its high recyclability.
100% Reusable
Scrap or used plasterboard can be processed into:
- New plasterboard sheets
- Soil conditioners used in agriculture
- Mine rehabilitation materials
Gypsum’s Benefits for Soil
- Enhances soil structure
- Improves water retention
- Stimulates root development and plant growth
- Reduces erosion and surface crusting
