Hello,

Just a quick question if I have a let's say a heat source of under a layer of bricks that have a thermal conductivity of 1.6 (W/m/°C.) and on top of the brick a layer of copper with a thermal conductivity of 398 (W/m/°C.).

Is my assumption right that since the layer of brick has such a low conductivity that no matter what material I put on top of that brick, that the maximum heat transfer between the heat source and the copper will be 1.6 (W/m/°C.) due to the low conductivity of the bricks?

Thanks in advance!

Within 1%, yes.
The total conductance will reduce to ≅1.59(W/m/°C), because you have added a tiny bit of thermal resistance with the Copper Sheet.

Cheers,
Tom
