What happens here

The host unseals the large rolls of R38 unfaced fiberglass batt insulation. He confirms that each roll contains eight pieces, each 24 inches wide and 8 feet long, covering 64 square feet. He then refers to the engineered plans, specifically noting the requirement for an R49 R-value in the ceiling. This confirms that the R38 fiberglass batts will be combined with the existing spray foam to achieve the target R49.

Goal: Fiberglass batt insulation rolls are unsealed, and the host reviews the engineered plans to confirm the R-value requirements for the ceiling.
