Abstract Increasingly extreme environmental conditions demand structural materials that combine mechanical robustness with sustainability. Natural wood is renewable and mechanically adaptable but suffers from high porosity and hydrophilicity, leading to moisture absorption, fire vulnerability, and environmental degradation. Ceramics provide high stiffness, thermal stability, and chemical resistance but are inherently brittle.

Graphical Abstract Thermal Insulation Bioinspired cement aerogel with ultralow thermal insulation, enables effective isolation from heavy snow accumulation and ensures optimal indoor thermal comfort. Its high porosity enables it to remain buoyant on a delicate plume. The profound implications of cement aerogel's properties are poised to revolutionize the construction sector by fostering the development of sustainable, energy-efficient structures that can withstand extreme weather conditions.
