由于实验室粉尘的测量量，铝箔的发射率增加。这些数据和水平放置铝箔样品的发射度测量，取自安装三到五年后的七个住宅阁楼。通过对以铝fofl为边界的阁楼空气空间的传热建模，可以预测随着表面发射度的增加，热流会增加。引用:研讨会，ASHRAE Trans。，第95卷，第。2.

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.
