What size insulation would you use on floor of a cabin on piers.? The floor joists are 2x8s?


Hello, while R-30 Batts (9.5” thick) may be compressed into a 2x8 (7.25” nominal) cavity, please check with your local building department or Lowe’s Pro Desk regarding R-value and vapor retarder requirements in your area. Thank you for your inquiry!
