There was a prior post about this stuff here.
The installation was failed because even at the R-4.2 (it also states "R-5.6 with airspace"-- that'd be interesting to see on a duct) is claims it provides, it's well below the R-8 NYS requires.
For reference, my code says:
The specification sheet is here. Is there anything else I should be looking for? I'm skeptical this will provide anywhere near R-4.2, but what do I know.
I'm a bit leary of the "Testing & Certifications" column on p2. Ok, it was tested to ASCM C518-- tested and failed? Or is it certified?
I would appreciate your thoughts. I don't care if they use it, as long as it complies.

Code:
N1103.2.1 Insulation. Supply and return ducts shall be insulated to a minimum of R-8. Ducts in floor trusses shall be insulated to a minimum R-6. Exception: Ducts or portions thereof located completely inside the building thermal envelope.
