Field evaluation of reflective insulation in south east Asia

The objective of this research was to obtain thermal performance data for reflective insulations in a South East Asia environment. Thermal resistance data (RSI, m2 K/W) for reflective insulations are well established from 1-D steady-state tests, but thermal data for reflective insulation in structur...
