This paper discusses the effect of employing different percentage of aerogel powder in paint solution for thermal insulating performance. This issue has led to the development of a fresh, inventive solution that has the ability to insulate against heat, allowing for a reduction in material thickness during construction. Due to its characteristics, aerogel is a great addition to coatings that are lightweight and thermally insulating. As an additive for the created thermal coating in the current investigation, different volume of aerogel ranging from 1% to 5% have been blended. The enhanced coating was then put to an ISO-NUD microporous panel in order to observe the effects of the aerogel addition. The testing results show that employing aerogel-infused coatings or paint can help an ISO-NUD microporous panel function better as a thermal insulator based on the temperature difference between the panel’s front and back surfaces. It became evident that a higher percentage of aerogel provide the better insulation. With the additional of 5% of aerogel, there was about 7% of thermal insulation enhancement that was recorded follow by the 5% of enhancement by addition of the 4% of aerogel. The additional of 3% and 2% of aerogel share almost similar level of enhancement which are about 3%. While the additional of 1% of aerogel seen unable to show significant enhancement compared to the normal paint without aerogel been infused.
