To determine

To Explain:The use of fiberglass as an insulator over wood in the buildings.

Explanation of Solution

Introduction:

The fiberglass is light-weight, less-brittle and a strong insulator. It is a reinforced plastic.

The fiberglass is used as an insulator because of its properties.The fiberglass is strong and available at a low cost. It is a good insulator and it is a non-combustible. Hence, it remains safe as compared to wood. It prevents the spread of fire in the building.

Conclusion:

Hence, the fiberglass is preferred over wood for insulation due to its properties and cost.
