Frequently Asked Questions
What size plasterboard should I use? 1200×2400 mm is standard. 1200×3000 mm reduces joints on taller walls. Use 12.5 mm for most walls; 15 mm for fire-rated (EI 60) or acoustic assemblies per EN 520.
How much waste should I plan for? 10% is typical for rectangular rooms. Use 15-20% for rooms with many corners or complex shapes.
