This invention solves the problem of developing transparent thermal insulation with high thermal resistance. The insulation is filled with an amorphous invisible medium whose all components have similar light diffraction and diffusion coefficients. The medium is a two-phase polymer-liquid system composed of a transparent spongy polymer skeleton 2 filled with a transparent liquid 3 with poor heat conductivity, both media having the closest possible light diffraction and diffusion indices. |
