As compared to other economical insulation options, cellulose provides good thermal performance with an R-value of 3.8 per inch. Cellulose insulation has received the highest fire safety rating (class 1), and can easily fit around items in your walls like pipes and wiring. Cellulose insulation is most often used in the cavities of walls and roofs to insulate, reduce noise, draught proof, and even provide added control against mold.
In this lesson, students in grades 3 through 8 assume the role of building engineers, testing several materials to determine which would provide the best house insulation. They learn about the role of insulation in preventing heat transfer and discuss the importance of energy conservation in buildings. Learning Objectives. After this activity, students should be able to: Describe how insulation works. Demonstrate how some materials insulate better than others; Relate that effective insulation helps conserve energy.
