During a home inspection, what aspect of insulation is critical to assess?

Assessing insulation during a home inspection is crucial because it directly impacts energy efficiency, comfort, and the overall performance of a home. Among the critical aspects to evaluate are the type, condition, and R-value of the insulation.

The type of insulation refers to the material used, such as fiberglass, cellulose, or foam, each having different properties and effectiveness. Understanding the condition of the insulation is equally important; damaged or wet insulation can lead to reduced performance and can also cause mold growth and structural issues. Lastly, the R-value measures thermal resistance; a higher R-value signifies better insulating properties, which is essential for maintaining comfortable indoor temperatures and reducing energy costs.

Evaluating these factors provides a comprehensive picture of a home's insulation performance and helps identify potential issues or upgrades needed to enhance energy efficiency.
