To provide a transparent porous body for heat-insulating, capable of being handled and drastically improving the strength without substantially deteriorating the excellent visible light transmittance and heat-insulating property of the silica aerosol and to furnish its production method.
A protective coating film of transparent resin is formed on the whole or a part of the surface of a transparent porous body for heat- insulating consisting of aerogel. A film 3 formed by laminating a low-density PE on the ethylene-vinyl acetate copolymer as a thermosoftening resin is recommended as the protective film. When the transparent porous body for heat-insulating is produced, the film 3 is placed on the surface of the porous body and evacuated in vacuum, and a protective coating film is formed on the surface of the porous body.
