AB  - Malaysia is located in the tropical region near to the equator, exposed to long hours of sunshine and
experiences high temperature and relative humidity throughout the year. In tropical countries, 75% of the heat
generation in a house come from the roof. Based on previous research, installing insulation on roof has
successfully given positive impacts on indoor temperature reduction. It was discovered that aerogel is the
current best solid insulation material where it has the lowest thermal conductivity of 0.02 W/m.K. However,
current usage of aerogel was only restricted in aeronautics, military, vessels and piping insulation. The
efficiency of aerogel as roof insulation material was simulated using Ecotect Analysis 2011 and to demonstrate
the real condition, the indoor and outdoor temperature of three small-scale houses was measured. The results
obtained from all stages of this research shows that aerogel induced the highest outdoor-indoor temperature
differences up to 8.1°C compared to aluminium foil and stone wool. From the energy saving cost analysis, it was
shown that aerogel reduced the energy cost in comparison with non-insulated roof the highest by 89%. These
results support the effectiveness of aerogel as roof insulation in residential building. It is recommended to
demonstrate the installation of aerogel in real house and further analysis on cost benefit analysis to be done
in future research.
