Question

maximum insulation is offered by :
a)metal b) wool c)timber d)glass

Answer 1

Hey!
Your answer is metal....

Answer 2

Timber can offer the best insulation out of the four given.

The insulating competency of timber is much higher from even wool. And this is why it is used in many construction purposes.

Especially in countries where winters are severer timber provides maximized insulation to the people living inside timber made walls. Due to the cheaper price of wool, it is also used in many places these days.

Imagine the interior wall of multiplex movie theaters. They are made from wool.
