Types of Plasterboard
Standard plasterboard is suitable for most general applications. Moisture-resistant plasterboard (green board) is ideal for bathrooms and kitchens. Fire-resistant plasterboard provides additional fire protection for safety-critical areas. Acoustic plasterboard reduces sound transmission between rooms.
Common Sizes
Plasterboard typically comes in 1200mm x 2400mm sheets. Thickness options include 9.5mm for ceilings, 12.5mm for standard walls, and 15mm for enhanced soundproofing or fire resistance.
Buying Tips
Always order 10% extra to account for cuts and waste. Check if delivery is included in the price. Consider buying in bulk for larger projects to get better rates.
