2. 25 cm cellular concrete

We would like to draw the reader's attention to one point: depending on the density (which can vary from 365 to 825 kg/m ³ ) of the aerated concrete used, its thermal conductivity coefficient λ will be between 0.145 and 0.29 W/m · °C.

The Glaser diagram for aerated concrete is based on a 450 kg/m ³ block, with a thermal conductivity coefficient λ of 0.16 W/m · °C and a water vapor permeability coefficient π of 200 · 10 ^–4 g/m · h · mmHg.
