Aerospace insulation shifts to aerogels to meet ICAO emissions rules

Airlines and OEMs are accelerating the replacement of traditional fiberglass insulation with ultra-light aerogels and ceramic composites, achieving weight savings of up to 20%. Driven by ICAO carbon reduction targets and high fuel costs, thermal and acoustic insulation specifications are increasingly prioritizing multi-functional, low-weight designs. This transition is sustaining segment growth at a projected 5.0% to 8.3% CAGR through the decade.
