Performance Testing of Radiant Barriers (RB) with R11, R19, and R30 Cellulose and Rock Wool Insulation
MetadataShow full item record
TVA has previously conducted testing to determine the effects of attic RBs when used with R19 fiberglass insulation during summer and winter conditions. This previous testing, and the testing described in this paper, used five small test cells exposed to ambient conditions. Heat flux transducers measured heat transfer between the attic and conditioned space. The objective of the testing described in this paper was to determine summer and winter RB performance when used with cellulose and rock wool insulations at R-vale levels of R11, R19, and R30. In addition, several summer side-by-side tests were conducted to determine the effects of: dust on RB performance, a low-emissivity paint, a high-emissivity material (black plastic) laid directly on top of the insulation, and single-sided RB placed on top of the insulation (RBT) with the reflective side down.
