Verify before building
Confirm measurements, product coverage, pack sizes, structural requirements, permits, and local codes before ordering or construction. Small measurement errors can produce material differences in area and volume.
Professional advice
Structural, life-safety, regulated, or unusually complex work should be reviewed by an appropriately qualified professional and the local authority having jurisdiction.
Site and product variation
Irregular surfaces, cutting patterns, weather, moisture, compaction, workmanship, tolerances, stock availability, and supplier practices can change actual requirements. Product manufacturer instructions take precedence over general planning assumptions.
