What happens here
Carefully cut and fit R-19 fiberglass insulation into the wall cavities and ceiling joist bays. Staple the insulation in place, ensuring good coverage. Once the insulation is in, install a thick plastic sheeting (Ace Premium 10ft x 25ft) as a vapor barrier, stapling it to the studs and joists. This prevents moisture from penetrating the insulation and damaging the wood framing. For the ceiling, drop the insulation in from above after the vapor barrier is in place, then seal the vapor barrier.
