Capacity depends on board layers, board type, studs, fasteners and load distribution. “Drywall” alone is not a complete specification.
Method basis: Rigips/Knauf system guidance and Fischer/Hilti fixing-selection principles. Final parameters always come from the selected product data.
How to plan the installation
Use approved cavity fixings for light loads. Transfer heavy, projected or dynamic loads to studs or reinforcement.
Common mistake
Do not multiply a single-fixing rating without the wall-system limits.
Pre-start check
- Was the structural base identified rather than only the finish?
- Does the weight include contents and projection?
- Were services, edges and minimum spacing checked?
- Does the product data permit the base, direction and environment?
