What is the role of baffles in attic insulation?

Baffles play a crucial role in maintaining proper ventilation in an attic space. They are typically installed along the eaves of the roof and serve to direct airflow from the soffit vents into the attic, ensuring that fresh air can circulate freely. This ventilation is essential for preventing moisture buildup, which can lead to mold growth and deterioration of insulation materials.

By facilitating the flow of air, baffles help to keep the attic environment balanced, allowing heat to escape in the summer and preventing heat loss in the winter. This is particularly important in maintaining an efficient insulation system, as proper ventilation complements insulation by regulating temperature and reducing the risk of condensation.

In contrast, baffles do not provide insulation support, block air from entering, or serve the specific purpose of insulating electrical lines. Their primary function is distinct and fundamentally related to the ventilation process, which is vital for the overall health of the roofing system and building performance.
