You must ask the manufacturer. Qualified energy efficiency improvements include
(A) any insulation material or system, including air sealing material or system, which is specifically and primarily designed to reduce the heat loss or gain of a dwelling unit when installed in or on such dwelling unit,
However, the system must meet,
the prescriptive criteria for such component established by the most recent International Energy Conservation Code standard in effect as of the beginning of the calendar year which is 2 years prior to the calendar year in which such component is placed in service.
So you must ask the manufacturer whether their system meets or exceeds the IECC code for 2021 for air-sealing systems.
Also, you can only claim the credit on the cost of materials, not installation. If you don't know, you can make a "reasonable allocation" of the cost from your overall invoice.
