Final answer:
Materials utilized as fire barriers within buildings may also be useful for insulation in buildings.
Step-by-step explanation:
Materials utilized as fire barriers within buildings may also be useful for other purposes such as insulation.
For example, well-insulated buildings need less energy for heating, and materials like mineral wool and polystyrene are commonly used for insulation due to their ability to hold air still and prevent heat loss.
Similarly, materials like fiberglass batts are used for insulation to prevent heat transfer between the inside and outside of a building.
