IGU Seal Failure Exposure at 13% expected seal failure occurrence share: a worked example

This worked example runs the igu seal failure exposure numbers for a tougher week than the baseline: 13% expected seal failure occurrence share instead of the typical 18%. Estimate IGU seal failure exposure from at-risk units, expected claim cost, occurrence scope, and fixed campaign cost.

The inputs for this scenario

  • IGUs at risk of seal failure: 680 IGUs (held at the documented default)
  • Average seal failure claim cost: 165 $ / IGU (held at the documented default)
  • Expected seal failure occurrence share: 13 % (the input this scenario stresses; the baseline uses 18)
  • Fixed seal failure campaign cost: 12,500 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable seal failure exposure = IGUs at risk of seal failure × average seal failure claim cost × expected seal failure occurrence share.
  • total IGU seal failure exposure works out to 27,086 $ at these inputs, and this is the headline figure for the scenario.
  • expected exposure per at-risk IGU works out to 39.83 $ / piece at these inputs.
  • variable seal failure exposure works out to 14,586 $ at these inputs.
  • fixed seal failure campaign cost works out to 12,500 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where expected seal failure occurrence share sits at 18% and the headline result is 32,696 $, this scenario comes in 17.16% below the baseline at 27,086 $.
  • Use it when a defective spacer, sealant, or desiccant lot is identified, or when field fog claims start clustering and you need to reserve dollars or justify a proactive reglaze. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • total IGU seal failure exposure: 27,086 $ (headline result)
  • expected exposure per at-risk IGU: 39.83 $ / piece
  • variable seal failure exposure: 14,586 $
  • fixed seal failure campaign cost: 12,500 $
