Abstract Aerogels show significant potential for subambient thermal regulation in energy‐efficient buildings and personal management under intense sunlight hot conditions owing to their unique combination of superinsulation solar scattering characteristics. However, traditional aerogels encounter challenges balancing mechanical flexibility with high‐temperature stability. Herein, a straightforward scalable cryopolymerization strategy is presented preparing superelastic thermomechanically robust silica‐sheathing nanofibrous aerogel. During cryopolymerization, cryogenic create an ice crystal‐constrained microenvironment interwoven cellulose nanofibers concentrated silicate monomers. This confined promotes the situ condensation polymerization high‐concentration silicates into porous silica nanoclusters predominantly on nanofiber surfaces, resulting aerogel composed bacterial nanocellulose cores encapsulated by sheaths. These demonstrate remarkable elasticity superinsulation, maintaining high stability even after prolonged exposure calcination at 800 °C direct 1200 butane flames. By precisely modulating mid‐infrared light, these achieve reflectivity 96.2% atmospheric window emissivity 97.5% extremely environments. Consequently, parasitic‐heat‐insulating serve as solar‐thermal regulatory cooling materials, achieving notable temperature reduction 11.4 environments conditions.
