Overview & Cost Implications
Type X fire-rated drywall is thicker and heavier than standard 1/2" panels. Its gypsum core contains glass fibers that slow the spread of fire, making it a building code requirement in specific locations.
Standard Formula Used
For estimating materials quantity and weight on job sites, estimators use this mathematical model:
Sheets = Total Area (sq ft) / 32 × 1.10 (waste) INTEGRATED ESTIMATOR
