The increase in the emittance of aluminum foils due to measured amounts of laboratory dusting has been measured. These data and emittance measurements for specimens of horizontally positioned aluminum foil, taken from seven residential attics three to five years after installation, are reviewed. Modeling of the heat transfer across attic air spaces bounded by aluminum fofl provides predictions of the increase in heat flow with increased surface emittance.
