Insulating a local, Pre-Fab home. 2x4 stud wall, offset from concrete wall, providing thermal break between the concrete and framing members. Aswell as Boxsill/Rim Joists providing air sealing, damp proofing, v***r barrier, and tying boxsill into wall insulation encapsulating double sill plate. Creating a monolithic thermal envelope throughout the basement.
We installed 2” of Closed cell 2lb density spray foam into the wall cavities, and applied 3” of closed cell into the Boxsill/Rim Joists. Giving the wall an R-14, and box’s R-21.
