8. Multi-layer walls
Now consider two masonry walls: the first insulated from the outside, the second from the inside. Let's draw diagrams showing the diffusion of water vapour through these two walls.
8.1 Temperature diagram
The temperature drop is proportional to the thermal resistance of the elementary layer through which it passes. The temperature drop is high in insulating material, low in masonry.
The temperatures on each side (inside and outside) of the two walls are identical, since the K coefficient of surface loss (see
