Fiberglass batt

Unfaced insulation is a lightweight thermal and acoustical fiber glass insulation made of long, resilient glass fibers bonded with an acrylic thermosetting resin. Unfaced batts are effective when controlling heat flow to the exterior, unwanted noise in internal walls, and to assist with moisture control, a separate vapor retarder can be applied.

Acoustical sealant used to bond poly to framing and seal poly to itself.

Rim Joist

In the framing of a deck or building, a rim joist is the final joist that caps the end of the row of joists that support a floor or ceiling. A rim joist makes up the end of the box that comprises the floor system.

The header is to a rim joist what the top or bottom wall plate is to an end stud.
