(d)
To find: The best and poorest insulating material.
(d)

Answer to Problem 42E
The best insulator is fiberglass insulation and poorest insulator is Gypsum wallboard.
Explanation of Solution
Given information: The given figure is as follows.
The best insulating material will have the highest temperature change per inch, because that will allow larger temperature difference on opposite sides of thinner layers.
From the above calculation, it can be concluded that the fiberglass insulation has highest temperature change so it will be best insulator.
The Gypsum wallboard has lowest temperature change so it will be poorest insulator.
Therefore, the temperature change in degree per inch for the wood sheathing is
