vented vinyl soffit?
Wow, I'm more screwed up than I thought. I only have a 12" soffit on my garage. Looks like I need to get the 16x4 under-eave soffit vents. Each one (according to the home depot website) is 26 NVFA? That seems too high.
So, if I use the ridge vent with 18 NVFA, and I have continuous soffit venting along both eaves with 26 NVFA, I should be good, yes? Absolute no chance of ridge reversal there!
EDIT: I think I'll just order the SV202 vent as recommended in the book (great book, btw!) and that will give me a more balanced airflow between the 18NVFA ridge vent, and the 9NVFA SV202 on both eaves. Thanks again for the awesome help, GBR. I owe you a case of beer.
