WebGlass foam obtained by melting powder glass together with carbon is a very hard, high compressive strength, easily broken, vapor-impermeable (μ = 10000) insulation material. Its thermal conductivity calculation value … WebSince we are talking about thermal insulation, that is, there is a small difference between them, since the thermal conductivity of the foam is 0.035-0.05 W / m * C, and the foam is 0.028 W / m * C. From this it follows that penoplex retains heat a little better.
