The Future of Thermal Insulation: Why Aerogels Are Gaining Traction in Modern Applications

Aerogel Industry Overview

The global aerogel market size was estimated at USD 1.38 billion in 2024 and is expected to register a CAGR of 17.0% from 2025 to 2030. Aerogels, known for their lightweight, insulating, and highly porous nature, have found use across various industries, including construction, aerospace, automotive, and electronics. As global energy consumption continues to rise, there is a pressing need for solutions that reduce energy loss. Aerogels offer exceptional thermal insulation properties, making them ideal for building insulation and thermal protection in industrial processes.

Aerogels are low-density materials that exhibit unique properties and are available in solid form. These are traditionally manufactured by using supercritical drying technology. However, advanced technologies have been developed to produce more efficient results. These are made by removing liquid from a gel using a specific procedure, resulting in a 3D nanoporous structure with an air range from 80 to 99%. These can be manufactured from any material but are commonly manufactured using silica called silica aerogel. However, some other materials used in their manufacturing are silica, polymer, and carbon, among others.
