Question

wood is a better insulator than glass so why is fiberglass commonly used as an insulator in wooden buildings why?

Answer 1

So that it may trap the solar radiations and maintain the temperature of the wooden building.

Step-by-step explanation:

Wood is not as effective an insulator as fiberglass. It comes in a number of widths, the widest being 3/4 inch, which has an R-value of 0.94. However, fiberglass, the thinnest of which is 3/4 inch, has an R-value of 3. Therefore, fiberglass is a better insulator.
