The global aerogel market was valued at approximately USD 1.38 billion in 2024, with projections for a compound annual growth rate (CAGR) of 17.0% from 2025 through 2030. Aerogels, renowned for being lightweight, highly porous, and effective insulators, are increasingly applied across various sectors such as construction, aerospace, automotive, and electronics. With a continued rise in global energy consumption, the demand for materials that effectively reduce energy loss is pressing. Aerogels meet this demand with their outstanding thermal insulation qualities, making them particularly valuable for building insulation and providing thermal protection in industrial processes.

Aerogels are low-density materials that retain unique properties in solid form. Traditionally, they are manufactured through supercritical drying technology, although newer technologies have emerged to enhance efficiency. Aerogels are created by removing liquid from a gel in a way that leaves behind a 3D nanoporous structure, typically containing 80 to 99% air. While they can be produced from various materials, silica aerogels are the most common type. Other materials used in aerogel production include polymer and carbon, which are selected based on specific application requirements.
