Which house is warmer – wood or stone, if the walls are the same thickness?

Every material in nature has such a property as thermal conductivity, or in other words, how quickly this material heats up or cools down. Wood has a low thermal conductivity, that is, if you heat a wooden house from the inside, then the heat through the wooden walls will pass outside for a very long time. The stone has a high thermal conductivity, that is, the heated heat is very quickly transferred to the stone walls and, accordingly, to the outside.

Therefore, the correct answer is: a wooden house is warmer.
