Plasterboard is the foundation of smooth, professional wall and ceiling finishes in residential and commercial projects alike. These versatile gypsum-based boards provide a flat surface ready for decoration while offering important benefits like fire resistance, acoustic insulation, and moisture control depending on the board type selected.
Our Plasterboard Range
We stock a comprehensive selection of boards to match every application and building requirement:
- Standard tapered edge plasterboard - Knauf standard plasterboard in tapered edge profile across multiple sizes (2438x1200mm and 2700x1200mm) and thicknesses (9.5mm, 12.5mm, 15mm), suitable for all basic dry lining, dot-and-dab, and stud partition requirements. Provides good acoustic performance against airborne sound.
- Standard square edge plasterboard - Knauf square edge boards in 1800x900mm format and 12.5mm thickness, suited to skimmed wall applications where a tapered edge joint is not required.
- Foil-backed plasterboard - Knauf tapered edge foil plasterboard in 2438x1200mm at 9.5mm and 12.5mm, with an integrated foil backing that enhances vapour resistance, reducing moisture transmission through the board in applications where condensation control is needed.
- Moisture-resistant plasterboard - Knauf moisture-resistant (green board) plasterboard in 2700x1200mm at 12.5mm, designed for use in kitchens, bathrooms, and other areas of high humidity where standard board would be at risk of moisture damage.
- Fireline plasterboard - Knauf fire-rated plasterboard in 1200mm width at 12.5mm, providing enhanced fire resistance for use in fire-rated partition and ceiling assemblies where building regulations require improved fire performance.
Complete your installation with our full range of Plastering Materials, including Jointing Compounds for seamless joints between boards.
Choosing the right board depends on the room's function, required fire rating, and whether additional thermal or acoustic performance is needed. Consider board thickness too — 12.5mm suits most standard applications, while 15mm provides added durability and improved sound insulation for high-traffic areas or noise-sensitive spaces.
