This is for a restaurant with with clear sectional door that will open up to a patio. anon (Unregistered Guest) Unregistered guest Posted on Monday, September 10, 2018 - 02:03 pm:    Internal air pressures?? Probably not, but exterior wind loads, yes. And also energy code requirements for u-factor and air leakage...

Assuming that some edition of IECC has been adopted as part of the code that applies to the project, the door also must meet requirements for eliminating air leakage. For example, I happen to have IECC-2012 in front of me, and see that Table C402.4.3 indicates a maximum air infiltration rate for "garage doors" of 0.40 CFM/square foot when tested at a pressure of 6.24 psf. The applicable code requirements for the specific project should be consulted, since it is possible that the door you are considering is classified as something other than a garage door, and other editions of IECC may have stricter requirements.
