An objective of this research is to assess the thermal insulation and energy
savings of paint that has been combined with silica aerogel. This research
conducted by testing paint with silica aerogel (PSA) compared with insulation
paint and typical paint. This research tested 3 paints by painting them on model
boxes (one for each paint) and exposing them to the light for the same amount of
time without a shadow effect. The result has shown that PSA had the best result. A
suitable mixer ratio of silica aerogel is 0.5 percent to make it practical and costeffective. When comparing rooms painted with PSA to rooms painted with typical
paint, the temperature was 4 degrees Celsius lower. PSA may also save 10
percent on air-conditioning electricity, with 6 months payback period. PSA has
good performance and the cost-effectiveness of PSA compared to typical paint is
the electricity cost savings and is more usable than insulation paint for thermal
insulation and price. PSA was painted on the building of Wat Phachoomtham
school in Chainat province of Thailand for the local community. It could lower
inside temperature and was suited for tropical conditions.
