I ended up buying the vinyl soffit at Lowes in the link above. It advertises 14.34 NFA per foot. I went to a different Lowes and the venting looked like it was properly formed so I'm convinced the other ones were not manufactured correctly. I will probably block or remove 12 ft of ridge vent...

Thank you for clarifying this. I agree the code could be clearer in some areas. I have a way of misinterpreting things if it isn’t explicitly stated. Another issue I have found is the difference between advertised NFA and actual NFA. I would advise people to do the math before buying. Two...

Thanks. That is probably the easiest option but Iools are also a factor.

Thanks. Maybe balanced was the wrong term. That is what I meant.

If I am interpreting the IRC code correctly as I posted above then you're right. If I used the vinyl soffit with 9.72 sq in NFA, I calculate that I would get a total of 427 sq in of intake ventilation. Since my eave is 6", that's half the width of the vinyl soffit, but since there are 2 sides...

bdbecker, Thank you for the detailed response. Do you interpret the IRC code as 1/300 of the attic area is the ventilation area needed for one side, exhaust OR intake, not the combination of exhaust AND intake area? In the code they say "net free ventilating area" and don't specify intake or...

Thanks everyone. bdbecker, I think I did the math wrong. I believe I thought the 1/300 rule was for calculating the exhaust only, not the combination of intake and exhaust ventilation. I have 1232 sqft of attic, so that’s 4 sqft of total ventilation required, or 2 sqft exhaust and 2 sqft...

Thanks eegger, Even the full vent soffit isn't enough NFA. The one in the link is 9.72 NFA per foot but it's 12" wide, so I would have to divide that by 2 since my width is 6".

I'm trying to figure out the best vent option for my soffit. I didn't plan out the overhang properly in the beginning, so now I have 6" between the brick backer board and the inside of the fascia board. I have a ridge vent that runs the entire length and it has a net free area of 18sq in per ft...

Thanks. Yeah maybe they need an age adjustment factor on that lighting guide :)

Can anyone give me advice on lighting my workshop? It is 44' x 28' x 10'. The ceiling will be white painted drywall. Walls will also be painted a light color. I'm leaning towards quality fixtures with a 5 yr warranty. I'll mainly be doing decorative concrete work so I think 50 fc/sqft is good...

I’m looking at a few different flashings. The SS seems like the superior option but not sure if it is necessary. Hohmann and Barnard Textroflash https://www.h-b.com/index.php?main_page=product_info&products_id=44 York 304SS flashing...

There is compacted gravel behind the wall, no crawl space. I did not insulate under the slab. I would think insulating the stem wall would have some effect on the garage temps especially where the wall is 42" but not sure how much.

Would you run the foam down close to grade(code says keep foam minimum 6" above grade in high termite areas) or just enough to lap the top of the stem wall and then waterproof the concrete so it runs down to flashing near 2nd course?

I am currently getting estimates from masons. The first one I met with said to put the through wall flashing where the osb meets the foundation(like my drawing), and no need for anything below this. For the portion below this flashing, which will vary from 12" to 42"(see my drawing in previous...
