  6. Knee wall defect: Often under-insulated and unvented, leading to ice dams and poor performance.
  7. Loose-fill vs. Batt: Loose-fill (cellulose, fiberglass) is blown in. Batt (fiberglass, mineral wool) comes in pre-cut sheets.
  8. Insulation over K&T: Can cause the old wiring to overheat, as it was designed to dissipate heat in open air.
  9. Crawl space ventilation purpose: Traditionally, to allow moisture to escape. Modern practice often recommends sealed, conditioned crawl spaces.
  10. Foam on roof deck: Must be carefully designed for the specific climate to avoid moisture condensation within the roof assembly.
  11. Whole-house fan: Cools the house by drawing cool night air through windows and exhausting hot attic air.
  12. Min insulation over living space: Typically R-30 equivalent, but local codes vary. IX. Interiors (Answers)
  13. Load-bearing vs. partition: Load-bearing supports structure above. Partition is non-structural, often runs parallel to joists.
  14. Water intrusion signs: Staining, bubbling paint, soft/delaminated drywall, mold, musty odor.
  15. Drywall cracks at doors: Often indicate foundation settlement or framing movement.
