R-13 Unfaced Mineral Wool Batt Insulation

ROCKWOOL Comfortbatt® is an unfaced mineral wool batt designed for wood or steel stud cavities to improve thermal performance and comfort.

  • Flexible Edge Fit: Friction-fits into stud bays for a snug hold and easier installation with less over-compression.
  • Fire Resistant Stone Wool: Non-combustible insulation designed to resist fire and limit smoke development.
  • Moisture Resistant Performance: Helps resist water and moisture for more durable in-cavity insulation.
  • Sound Absorbency: Dense mineral wool helps reduce noise transfer between rooms and floors.
  • Healthier Indoor Air Support: GREENGUARD Gold Certified to support a healthier indoor environment.
