Achieve steady comfort and energy efficiency in your home with the Owens Corning Kraft Faced Fiberglass Insulation Roll. Measuring 15 in wide by 384 in long and delivering 40 sq ft of coverage, this roll provides an efficient way to fill 2x4 wall cavities and attic spaces with reliable R-13 insulation performance.
- 15" wide x 384" long (32 ft), totaling 40 sq ft of insulation coverage per roll.
- 3.5 inches, designed to fit standard 3.5" deep wall cavities common in 2x4 construction.
-
R-Value: R-13 insulation performance for effective thermal resistance in residential applications.
-
Facing: Kraft-faced insulation provides a built-in moisture barrier and a convenient vapor retardant layer for controlled condensation in colder climates.
-
Material: Fiberglass insulation roll that’s easy to handle, cut, and fit between standard framing.
-
Ideal for: New construction with 2x4 studs, retrofit projects in tight spaces, and attic floor applications where a compact roll is advantageous.
Why this Kraft-Faced roll stands out
Unlike unfaced insulation, the Kraft facing adds a moisture-control layer that helps manage condensation and improves overall wall assembly performance in many climates. The roll format minimizes seams in long runs, reducing gaps where heat could escape and making it simpler to cover larger areas quickly—an advantage on both remodels and new builds.
Smart installation tips
- Center the roll in the cavity and cut to length with a sharp utility knife for clean edges that seal well against framing.
- Place facing toward the interior living space, then staple the facing to the studs to keep insulation in place while avoiding compression that would reduce R-value.
- When filling top-to-bottom in a wall, avoid compressing the batt; maintain its thickness to preserve the rated R-13 performance.
- In attic applications, lay rolls across joists, overlapping edges as needed to minimize gaps and improve overall thermal performance.
With Owens Corning, you’re choosing a trusted fiberglass insulation solution that pairs reliable thermal resistance with practical moisture management. This Kraft-faced roll is ready to help you create a more comfortable home, reduce cold drafts, and support energy-conscious living in everyday projects—whether you’re insulating new walls or upgrading an existing space.
