Does Inflation Reduction Act cover Duct sealing?

[Yoyoguy]

I am bit confused whether 25C under Inflation Reduction Act cover duct sealing. It mentions, that air sealing is covered though.

Products that air seal (reduce air leaks) can also qualify, as long as they come with a Manufacturers Certification Statement, including:

• Weather stripping
• Spray foam in a can, designed to air seal
• Caulk designed to air seal
• House wrap

Tax Credit does NOT include installation costs.

Thanks! Possible to share the verbiage, where it says only materials, and the list of materials shared above? 

I am reading this https://www.congress.gov/bill/117th-congress/house-bill/5376/text, where it says labor costs are covered. Can you pls clarify that I wanna be double sure?
