How do inspectors evaluate insulation in attics and walls?

Inspectors evaluate insulation in attics and walls primarily by checking for coverage and signs of damage. This comprehensive assessment is crucial because it provides information about the effectiveness of the insulation in maintaining energy efficiency and climate control within the home. Adequate coverage of insulation ensures that heat transfer is minimized, which is vital for energy savings and comfort. Signs of damage, such as compression, moisture, or pest infestations, can significantly impact the performance of insulation, leading to potential problems like increased energy bills and the risk of mold growth. Inspectors pay close attention to these factors to ensure that insulation meets the necessary standards and effectively protects the home's integrity.

While other aspects, such as the color of the insulation or its thickness, can provide some insight into its type or age, they do not necessarily correlate with the insulation's effectiveness in terms of thermal performance or its condition. Thus, the most relevant evaluation criteria focus on thorough coverage and the condition of the insulation material.
