Just what I needed to 'attempt' to correct my hot attic in my 66 year old home. Thanks!
We're glad you found this vide helpful, Bill!
Good video, thank you.
This video is like having to take algebra during the summer😄😁😆
Can I use a SSB960 as intake near the bottom of the roof?
SSB960 is an exhaust vent and should not be used as intake
Great Information.! I am currently building a new home and would like to make sure adequate ventilation is in place as ive had issues in the past.
I am confused as to exactly what are should be used for the calculation though.
Is it the total area of the House "Under Roof" (House, Porch, garage, lanai etc) OR is it only the areas above the air conditioned space?
Thanks!

Thank you for the info, but it really doesn't help me know which Attic space needs venting, or is it simply anything under a roof.
Im still a bit confused.
