Standard vs. Specialty Plasterboard: What’s the Difference?

When it comes to wall and ceiling linings, plasterboard is the go-to solution for Australian builders and DIYers. But not all plasterboard is created equal. Choosing between standard and specialty plasterboard depends on where and how you're using it. In this guide, we break down the key differences to help you select the right product for your project.

What Is Standard Plasterboard?

Standard plasterboard is your everyday sheet for most internal walls and ceilings. It's lightweight, easy to cut, and ideal for dry areas in residential or commercial builds.

For example, Siniat 13mm Mastashield is a popular general-purpose option that provides a smooth finish and is suitable for painting or decorative coverings.

What Is Specialty Plasterboard?

Specialty plasterboard includes boards that are engineered for specific conditions, such as:

• Acoustic Plasterboard: Like Siniat Soundshield, designed to reduce sound transfer between rooms.
• Fire-Rated Plasterboard: Such as Siniat Fireshield, which improves fire resistance in compliance with building regulations.
• Moisture-Resistant Plasterboard: Ideal for wet areas like bathrooms and laundries (often coloured green).
• Impact-Resistant Plasterboard: For high-traffic areas like schools, hospitals, or apartment hallways.

When to Use Each Type

Use standard plasterboard for dry areas like living rooms, bedrooms, and hallways in residential settings.

Use specialty plasterboard in areas with specific needs — noise control, fire safety, high humidity, or extra durability.

Cost Considerations

Standard plasterboard is more cost-effective, making it ideal for large-scale builds. Specialty plasterboard is slightly more expensive but essential for meeting compliance or performance needs in specific zones.
