Acoustic Fiber Cost at 65% usable fiber yield: a worked example

This worked example runs the acoustic fiber cost numbers for a tougher week than the baseline: 65% usable fiber yield instead of the typical 90%. Estimate fiberglass, mineral wool, or PET fiber cost from treated area, material rate, usable yield, and fixed handling cost.

The inputs for this scenario

  • Fiber area required: 520 sq ft (held at the documented default)
  • Fiber material cost: 4.2 $ / sq ft (held at the documented default)
  • Usable fiber yield: 65 % (the input this scenario stresses; the baseline uses 90)
  • Facing/handling cost: 240 $ (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Fiber subtotal = fiber area required × fiber material cost × usable fiber yield.
  • Total fiber cost works out to 1,660 $ at these inputs, and this is the headline figure for the scenario.
  • Fiber cost per sq ft works out to 3.19 $ / sq ft at these inputs.
  • Fiber material subtotal works out to 1,420 $ at these inputs.
  • Facing/handling cost works out to 240 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where usable fiber yield sits at 90% and the headline result is 2,206 $, this scenario comes in 24.76% below the baseline at 1,660 $.
  • Use it when quoting fibrous absorbers, weighing fiber against foam, or pricing the scrim facing and handling that fiber media demand. 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.
