Light-weight ceramic aerogels hold promise for superinsulation. However, its mechanical instability and complex manufacturing hampered technical applications. In this study, we demonstrate lightweight pore-gradient aerogel-like foam monoliths (PGAFoams) through one-pot in situ bubble supported pore gradient formation. The mechanically strong PGAFoams exhibit a low thermal conductivity of 0.036 W m-1 K-1 compressive strength 89.85 MPa. integral monolith nature provides such hydrophobic with management, robust soundproof, fire-resistance performance. Highly machinable can be adapted into variety shapes dimensions to accommodate geometry scalable opens up building insulation remarkable high strength, mass density, superior soundproofing, fire-retardant performances.
