re: Attic ventilation

I know. But I figured there was plenty of info to sort out without getting into exceptions and percentages. If it’s split high and low (40-50% high?) it can be 1/300. But if you have a continuous perforated soffit you end up with nearly 1/150 anyway to get the ratios to work.

I’m pondering the same issue. My question: can you have too much attic ventilation. My soffit vent seem sparse with some exterior walls having none in 20’ or so. I’ve got a ridge vent up top. Thx. I’m thinking of adding some whirly gigs but don’t want to f it up.
