Experiments and computer simulations were conducted to evaluate the performance of radiant barriers under three different insulation levels in residential applications. The experiments were conducted in central Texas, USA using side-by-side comparisons in which two houses, with identical floor plans and thermal profiles, were used. The houses were instrumented, calibrated, and their heat transfer rates across the ceilings were measured and recorded. A heat and mass transfer model was used to run the computer simulations.
