Measurements and specifications of gypsum walls in interior finishes
Gypsum boards vary in core, facing, edges and intended use. Record these from product documentation rather than paper colour alone or a dimension without units.
Specify gypsum-board dimensions, thickness and support for the product and assembly. Moisture resistance does not mean waterproofing or freedom from mould in every condition. Review joints, openings, insulation and exposure as a complete system.
The system includes framing, fixings, joints, openings and services. Coordinate protection and maintenance requirements without turning a board’s marketing description into an entire wall rating.
