Engineer Dexter de Castro from Naga City, Camarines Sur, has developed a thermal insulating powder capable of reducing indoor temperatures by 30% to 60% when applied as a coating or paint.
As reported by GMA News’ Balitang Bicolandia, this project was inspired by NASA’s technology. Invented in 2019, it utilizes a coat used in space shuttles, composed of pre-cracked ceramic tiles with high silica content, alumina, and nano ceramic particles, as its model.
De Castro’s powder, made from a mixture of soil and silica clay or white clay, has undergone testing by Engineer Junval Parco. After application to walls directly exposed to heat, Parco noted a significant reduction in temperature with just two coatings. Formerly struggling to sleep due to the heat, he now finds his walls much cooler.
Parco has integrated the powder into his projects, receiving positive feedback from customers. De Castro offers a bucket of insulating powder for PHP1,620 and a kilogram for PHP330. He also plans to patent his invention, a process that typically takes 48 months.
