Insulation Board Yield at 99% target insulation board yield: a worked example

Push target insulation board yield up to 99% and the picture changes. This example computes every intermediate figure at that operating point. tracking insulation board material yield for production or purchasing

The inputs for this scenario

  • Accepted insulation board area installed: 9,800 sq ft (unchanged)
  • Insulation board material issued: 10,600 sq ft (unchanged)
  • Target insulation board yield: 99 % (raised for this scenario; the documented default is 95)

Working through the calculation

  • Applying the documented formula (Insulation board yield = accepted insulation board area ÷ issued insulation board material area × 100) to the inputs above produces each figure below.
  • At this operating point the engine returns 92.45 % for insulation board yield, the number this scenario is built around.
  • At this operating point the engine returns 6.55 points for insulation board yield gap to target.
  • At this operating point the engine returns 9,800 count for accepted insulation board area.
  • At this operating point the engine returns 10,600 count for issued insulation board material area.

How this compares with the baseline

  • Against the tool's baseline example, where target insulation board yield sits at 95% and the headline result is 92.45 %, this scenario lands almost exactly on the baseline at 92.45 %.
  • It computes the percentage of issued insulation board that became accepted installed board, plus the point gap to your target yield. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • insulation board yield: 92.45 % (headline result)
  • insulation board yield gap to target: 6.55 points
  • accepted insulation board area: 9,800 count
  • issued insulation board material area: 10,600 count
