With a total coverage area listed at 89.13 sq ft, you can plan for fewer seams and quicker progress on larger projects.
Key specifications
- Dimensions: 23 in. W × 93 in. L × 5.5 in. T
- R-value: 21
- Coverage area: 89.13 sq ft per package
- Facing: Kraft faced (paper) for a built-in vapor retarder
What makes this insulation stand out
-
Kraft-faced convenience: The kraft paper facing provides a built-in moisture barrier and a ready-to-staple surface, helping seal cavities as you install and contributing to more efficient air control in living spaces.
-
High thermal resistance in a deep cavity: With an R-value of 21 in a 5.5 in thick batt, this product is well-suited for 2x6 wall constructions and other thick cavities, delivering stronger resistance to heat flow where it matters most.
-
Bulk coverage with fewer seams: The 23 in. width and 93 in. length help cover larger wall sections and attic gaps, reducing the number of cuts and seams you need to manage.
Ideal applications
- New construction or retrofit projects involving 2x6 stud walls where higher insulation values are desired
- Attic and ceiling spaces where you need substantial R-value without stacking multiple layers
- Residential renovations aimed at improving energy efficiency, reducing drafts, and stabilizing indoor temperatures
Practical installation tips
- Measure cavities carefully, then cut the batt with a sharp utility knife and straightedge to fit around electrical boxes, pipes, and wiring.
- Avoid compressing the material—let the batt fill the cavity to maintain the full R-value.
- Install with the kraft facing toward the interior side of the wall or ceiling to maintain the vapor retarder function and provide a clean surface for finishing.
- Seal edges and joints as you go to minimize air leakage and maximize thermal performance.
Whether you're upgrading an older home or outfitting new construction, this Owens Corning kraft-faced fiberglass insulation batt offers robust thermal protection, straightforward installation, and a dependable vapor-retardant layer.
