Plasterboard

Plasterboards: The Foundation of Every Interior Wall and Ceiling

Plasterboard is where smooth walls and clean ceilings begin. Whether you’re framing a new home, renovating an existing space, or tackling commercial fit-outs, quality plasterboard delivers the stable, workable surface that painters, tilers, and finishers depend on. No warping, no sagging, no callbacks.

At Blacktown Building Supplies, we stock Knauf Plasterboards & Accessories because it’s the brand that professionals trust for consistent performance. From standard wall sheets to specialised ceiling and wet-area applications, we’ve got the right board for every interior construction job.

Engineered for Easy Drywall Constructions

Knauf plasterboards are manufactured specifically for Australian conditions, with gypsum cores and paper facings that handle our climate extremes. Each sheet is precision-cut and quality-controlled to ensure flat, square boards that install cleanly and finish smoothly.

Whether you’re working on residential renovations or commercial drywall construction, Knauf boards provide the dimensional stability and surface quality that make the difference between amateur and professional results.

• Standard wall sheets in 10mm and 13mm thickness for different structural requirements
• Ceiling-specific boards engineered for overhead installation without sagging
• Wetstop moisture-resistant sheets for bathrooms, laundries, and wet areas
• Multiple length options, including 2400mm, 3000mm, and 3600mm for reduced joints
• Consistent 1200mm width for standard stud spacing and easy handling

Where Quality Plasterboard Makes the Difference

From new construction to renovation work, plasterboard handles the interior applications that matter:

• Residential Drywall Construction for walls and ceilings in bedrooms, living areas, and hallways
• Bathroom Renovations using Wetstop boards for moisture-prone areas
• Commercial Fit-outs creating partition walls and suspended ceilings in offices
• Ceiling Installation with specialised boards designed for overhead applications
• Renovation Projects replacing old fibro or damaged plaster walls
• Acoustic Applications using thicker boards for improved sound control

Choose the Right Board for Each Application

Different areas of your build require different plasterboard specifications:

Standard 10mm sheets work perfectly for most wall applications where basic impact resistance is needed. Thicker 13mm boards provide extra strength for high-traffic areas and improved acoustic performance. Ceiling boards are specifically engineered to resist sagging when installed overhead.

Wetstop boards feature moisture-resistant cores and specially treated paper faces that handle bathroom and laundry environments without deteriorating or losing bond strength.

Knauf Plasterboards – Quality You Can Count On

Knauf has been manufacturing plasterboard for over 80 years, and that experience shows in every sheet. Consistent thickness, square edges, and smooth faces that take paint, wallpaper, and tiles without problems. When you specify Knauf, you’re specifying reliability.

Each board meets Australian Standards for performance and fire resistance, giving you confidence in both residential and commercial applications.
