How to use it

Describe the surfaces and fastening plan

  1. Choose wall, ceiling, or combined.
  2. Enter surfaces and openings.
  3. Enter actual sheet and framing details.
  4. Use a sourced preset only when applicability matches, or enter a verified custom rule.
  5. Optionally add package and cost inputs.

Grid method

Separate joint-side fastening rows

The TypeScript Calculator Core counts unique edge and field positions. Adjacent panels retain separate edge-fastener rows even on a shared framing member.

  • Special, tested, fire-rated, and proprietary assemblies require separate verification.
  • Package size, price, currency, and allowance remain user inputs.

USG single-layer product guidance

The sourced presets use USG Sheetrock Brand Installation and Finishing Guide J371/rev. 9-15 and are not universal building-code rules.
