Radiant Barrier Insulation Performance in Full Scale Attics with Soffit and Ridge Venting
MetadataShow full item record
There is a limited data base on the full scale performance of radiant barrier insulation in attics. The performance of RBS have been shown to be dependent on attic ventilation characteristics. Tests have been conducted on a duplex located in Florida with soffit and ridge venting to measure attic performance. The unique features of these experiments are accurate and extensive instrumentation with heat flow meters, field verification of HFM calibration, extensive characterization of the installed ceiling insulation, ventilation rate measurements and extensive temperature instrumentation. The attics are designed to facilitate experimental changes without damaging the installed insulation. RBS performance has been measured for two natural ventilation levels for soffit and ridge venting. Previously, no full scale data have been developed for these test configurations. Test data for each of the test configurations was acquired for a minimum of two weeks with some acquired over a five week period. The Rl9 insulation performed as expected.
