Herein, we adopt an in situ polycondensation method to induce confined growth of a uniform face\u2010connected network within partial pores of nanofiber frameworks, and successfully synthesize face\u2010bridging silica aerogels (FBSAs). Relying on the interlocked face\u2010bridging microstructure, the as\u2010prepared monolithic aerogels gain improved structural robustness, high specific strength, and reduced thermal conductivity simultaneously. Versus conventional point\u2010crosslinked silica aerogels, FBSAs exhibit greatly enhanced mechanical properties: a compressive strength of 318 kPa at 80% compression strain, tensile strength of 120 kPa, and flexural strength of 390.8 kPa. With an ultralow density ranging from 35 to 50 mg cm\n                    <jats:sup>\u22123<\/jats:sup>\n                    , the material achieves a specific strength of 6.36 MPa cm\n                    <jats:sup>3<\/jats:sup>\n                    g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , which is two to three times higher than that of typical ceramic fiber aerogels. Moreover, the aerogel delivers a room\u2010temperature thermal conductivity of 0.028 W m\n                    <jats:sup>\u22121<\/jats:sup>\n                    K\n                    <jats:sup>\u22121,<\/jats:sup>\n                    comparable to conventional silica aerogels. It maintains stable thermal insulation between \u2212196\u00b0C and 1100\u00b0C, and can withstand short\u2010term exposure at 1300\u00b0C. This confined growth strategy provides a reliable route to fabricate high\u2010performance monolithic silica aerogels.\n
