How should you install insulation when installing attic side vents?

When installing insulation in relation to attic side vents, maintaining a distance of 12 inches away from the vent opening is important to ensure proper ventilation. This practice helps to facilitate the flow of air, allowing for the effective functioning of the vents. Proper ventilation plays a critical role in preventing moisture buildup and reducing the risk of mold and mildew, which can compromise the structural integrity of the attic space.

By keeping insulation at this specified distance, you're allowing adequate airflow. It prevents insulation from obstructing the vents, which could otherwise lead to heat buildup or hinder the cooling of the attic space. This practice is in line with building standards and guidelines that emphasize ventilation as a key aspect of maintaining an energy-efficient and healthy environment in the attic.

Other options, such as covering the vent opening with insulation, would obstruct airflow and defeat the purpose of the vent, leading to potential moisture issues. Installing insulation below the elevation of the vent opening may also create similar issues, as it could cause air stagnation. Therefore, the separation of 12 inches is the recommended best practice for installing insulation around attic side vents.
