vent area per sq ft of floor??
Hi:
I can't find or remember the amount of net free vent area (attic) required per sq ft of floor space.
Sure would appreciate getting me straightened out.
IS there an on-line source for reading the UBC (like there is for the NEC)?
Cheers,
s/Mike

Attic ventilation is usually determined using 1/300 the square footage of the attic space. You then split this surface area between soffit screens and either ridge vents or pot vents.
