I submit that if one is to consider the spray foam insulation as unobstructed as defined by -13, then the deflector position relative to the bottom level of the foam is required to be between 1" and 12" per 10.2.6.1.1 ('22 edition). If the bottom of the insulation is to be considered as obstructed, or the foam is between members which are obstructed, then the deflector must be 1" to 6" below the member, but no greater than 22" down from the ceiling/roof deck above, per 10.2.6.1.2 ('22 again). I can't wait to learn the rationale behind such a requirement. In short, remember my oft repeated mantra, whenever someone pops up with something like this: Prove it. keep the forum informed, ok?

His reasoning was that the uneven nature of the foam application could cause obstructions that weren’t readily apparent so extra clearance was warranted.
