What strategy is used to minimize airflow issues in insulation?

Minimizing wind washing is a key strategy for reducing airflow issues in insulation. Wind washing occurs when air passes through insulation materials, such as fiberglass batts, reducing their effectiveness by lowering their R-value (thermal resistance). This can happen if the insulation is not properly installed or if there are gaps and spaces that allow air movement. By improving the fit of insulation and potentially using air-blocking materials or techniques, the airflow can be restricted, which helps maintain the intended thermal performance of the insulation. This approach ensures that the insulation performs effectively, helping to maintain a comfortable indoor environment and improve energy efficiency.

Enhancing window size or adjusting room temperature are not directly related to minimizing airflow issues within the insulation itself, while sealing exterior paint edges does not address the airflow problem in the context of insulation performance.
