What’s in a plasterboard and why use it?

Because it’s cost-effective, easy to install and provides a smooth surface that’s easy to finish,  plasterboard is a go-to building material for builders and DIYers. These building sheets are commonly made by sandwiching gypsum paste between thick layers of paper or other facing material. 

However, depending on their type, plasterboard can be engineered with special additives and materials to improve its performance and provide extra features like insulation, moisture-resistance, and more. Let’s explore below the most common types of plasterboard and where to use them.

 

Types of Plasterboard

1. Standard plasterboard

The most basic form of plasterboard with no specialised features, standard plasterboards are usually used in internal walls and ceilings of areas. 

Recommended use: Spaces where there are no specific requirements for moisture, fire-resistance, and so on. 

 

2. Fire-rated plasterboard

Commonly covered in pink paper, fire-rated plasterboards incorporate ingredients to improve fire performance and resistance. These plasterboards are designed to slow down and contain the spread of fire. This helps maintain structural integrity during fire, allowing you extra time for escape in such emergencies.

Recommended use: Areas that need higher fire protection, like party walls, escape routes like stairwells and corridors, and high-risk areas like kitchens and garages. Homes located in bushfire zones are also recommended to use fire-rated plasterboards to meet BAL requirements.

 

3. Moisture-resistant or wet area plasterboard

Made using water-repellent additives or coatings, wet area plasterboard often has a low absorption core to withstand humidity and moisture that often damages homes. Depending on the manufacturer, they can be covered with a light blue or green facing to indicate their special features.

Recommended use: wet areas like bathrooms, kitchens, laundry areas, or crawl spaces where pipes run. Those who live in coastal areas in Perth that experience high humidity during the wet season can also use wet area plasterboards in external ceilings.

 

4. Acoustic or sound-rated plasterboard

Installing acoustic building materials like sound-rated plasterboard for homes is a great way to maintain your family’s privacy, peace and comfort. These are usually made denser, with materials like glass fibres that help absorb sound.

Recommended use: rooms that need enhanced privacy and quiet, like bedrooms, media rooms, and home offices. Acoustic plasterboards can also be used in party walls and ceilings in apartment settings.

 

5. Impact-resistant plasterboard

Siniat Impactshield, a type of impact-resistant plasterboard.

Made dense and tough, impact-resistant plasterboards feature heavier paper liners for increased durability as well as improved acoustic performance. As the name suggests, they’re highly resistant to soft and hard body contact. 

Recommended use: high-traffic or high-activity areas like entryways, hallways, garages, home gyms, and workshops.

 

6. Flexible or curved plasterboard

Siniat curveshield, a type of flexible plasterboard for curved surfaces.

Specially designed to be thinner yet still durable, flexible plasterboards can bend to desired shapes. This allows installation for curved surfaces without the need for dampening or scoring plasterboards, which can affect their durability.  Convenient and easy to handle, flexible plasterboards offer flat, blemish-free surfaces that are ready to paint once installed.

Recommended use: curved features like walls, ceilings, arches, or columns.

 

Factors to consider when building in WA

Aside from the type of space you’re planning to construct, other environmental factors also come into play when choosing the types of plasterboard to use. In WA, where we experience scorching hot summers and cool, wet winters, the plasterboard type you choose for your project can make or break the longevity of your home. Before going ahead, consider the following:

 

Bushfire zones

“Do I need to use fire-rated plasterboard?” It ultimately depends on your location. 90% of WA is bushfire-prone because of our long dry summers and vegetation.  Depending on where you live and your bushfire attack level (BAL), you might be required to use BAL-rated building materials that meet standards such as non-combustible plasterboard with high fire resistance. Check if your area falls under a bushfire-prone zone through the DFES’s map.

 

Humidity, moisture, and precipitation levels

The amount of humidity and rain you experience will also affect the structural integrity of your build. Consider moisture-resistant plasterboards if you live in an area that has wet, rainy winters or if you experience a green season with high humidity. These weather conditions encourage the build-up of moisture, and, along with it, moulds and eventual rot.
