I’m planing the ventilation for my attic. I’m going to have loose fill cellulose to an R-60 and a friend of mine was mentioning that I don’t need to vent the soffits if I have gable vents and ridge vent because the house will be air tight. He was also mentioning over ventilating and possibly doing something with the pressure of the house. Anyway I had planed on using soffit vents as it seemed to be the fail safe way for venting. The house will have an HRV system also.
