Is Fresh Air Exchange Needed for an Attic Insulated with Spray Foam?
Asked by CuriousCat123
I'm exploring options for better insulation in my attic, and spray foam insulation seems like a popular choice these days. Since spray foam can create a tight seal, I'm wondering if I still need to implement a fresh air exchange in the attic. What are your thoughts on this?

Generally, you don't need a fresh air exchange with spray foam insulation, but once your attic is sealed, it should be conditioned like the rest of your home. This helps in maintaining balanced air quality and temperature.
