This lesson covers the most important installation issues you’ll encounter when inspecting insulation. Insulators should install insulation in ways that optimize its effectiveness, but insulators often install insulation incorrectly. This lesson covers how to evaluate the performance of installed insulation. You’ll learn the following.
- Why insulation’s energy-performance is often less than its rated R-value.
- How other building factors, including air leakage, affect insulation’s effectiveness.
- How to select insulation that’s best suited to your project’s purpose, location, and budget.
