Summary

How do aerogel coatings achieve ultra-thin thermal insulation?

In the realm of traditional thermal insulation, achieving high efficiency usually requires thicker insulation layers; aerogel coatings, however, break this convention. An aerogel coating just 1 millimeter thick offers thermal insulation performance equivalent to 10–30 millimeters of traditional polystyrene board, making it an ideal choice for energy-efficient buildings and high-end equipment.
