✅The Ultimate Home Building Checklist on my site #BuilderBrigade✅ These baffles are installed so air can flow from the soffit into the attic space. Without these baffles, blown-in insulation would get in the way of airflow from the soffit to the attic. If spray foam is used, the attic is sealed off so ventilation from the soffit is not required. Would you have known what these baffles were if you saw them in your build?#Soffit #soffitvents #durovent #atticvent #sprayfoaminsulatopm#BuilderBrigade
