When choosing unfaced insulation, 23-inch-wide rolls are a practical fit for many 2×6 wall cavities and attic spaces. This guide highlights top unfaced and closely related insulation rolls that align with the 23-inch width and efficient thermal performance. We cover product details, installation considerations, and buying tips to help you compare options for energy efficiency and indoor comfort.
Summary of chosen products:
- Owens Corning R-19 Faced Fiberglass Roll, 23″ Wide (Faced, but commonly used with unfaced installations in similar widths)
- EcoRoll Kraft R-19 23″ Wide Faced Fiberglass Insulation Roll
- Owens Corning R-13 Pink Kraft Faced Fiberglass Insulation Roll, 15″ Wide (closest in roll format for comparison)
- INSULATION MARKETPLACE SmartSHIELD -3mm 24x50Ft Reflective Roll (not unfaced, but relevant as a radiant barrier option for certain assemblies)
- SmartSHIELD -20mm 48″ X25ft Reflective Roll (larger width, comparable reflective insulation option)
Owens Corning R-19 Faced Fiberglass Roll 23″ Wide
Product overview: This 23-inch-wide faced fiberglass roll is designed for 2×6 walls, floors, crawlspaces, and attics. It delivers strong thermal control with notable acoustical performance and reduced dust during handling. The roll offers stiffness and recovery characteristics typical of EcoSoften formulations, making it a practical choice for homeowners seeking reliable insulation performance in standard residential cavities.
EcoRoll Kraft R-19 23 Inch Wide Faced Fiberglass Insulation Roll
Product overview: This 23-inch-wide faced roll features a GREENGUARD Gold certification and uses a natural binder derived from corn, sand, and recycled glass. Free of red-list chemicals and formaldehyde, it’s soft to the touch and easy to cut, split, and install. The Kraft facing helps manage moisture exposure while maintaining thermal performance in standard wall assemblies.
Owens Corning R-13 Pink Kraft Faced Fiberglass Insulation Roll, 15 in. x 32 ft. (3)
Product overview: A R-13 faced roll designed for exterior/interior 2×4 walls, with easy handling and installation. While it’s 15 inches wide, it remains a relevant comparison for practitioners focusing on kraft-faced options and traditional fiberglass performance in compact stud bays. The insulation helps with temperature stability and noise control, and it is formaldehyde-free for indoor air quality considerations.
INSULATION MARKETPLACE SmartSHIELD -3mm 24inx50Ft Reflective Roll
Product overview: This reflective insulation roll acts as a radiant barrier with a foam core. It reflects up to 95% of radiant energy, helps reduce heat transfer, and can function as a vapor barrier in appropriate climates. Its foil surface and barrier properties can complement unfaced insulation in hybrid assemblies, particularly for attic or duct insulation projects.
SmartSHIELD -20mm 48″ x 25ft Reflective Insulation Roll
Product overview: This foam-core radiant barrier offers high reflectivity and a substantial R-value potential when layered. It serves as a vapor barrier and moisture-resistance option that can be used in both indoor and outdoor contexts. The 48-inch width broadens coverage for larger applications while maintaining R-value benefits through reflective performance.
Buying Guide: Key Purchase Considerations
- Width compatibility: For 23-inch-wide rolls, confirm the exact cavity width and stud spacing (commonly 2×6 in many U.S. homes) to ensure a snug fit with minimal cutting and waste.
- Facing vs. unfaced: Faced products add a kraft or foil facing for vapor control and easier installation in some assemblies. If you specifically need unfaced insulation, verify product specifications and intended use in your local building codes.
- Thermal performance: R-value per inch, overall R-value, and the impact of density on air sealing. Higher density and proper installation reduce air gaps and maximize energy savings.
- Air sealing and moisture control: Consider complementary air barriers or vapor retarders, especially in damp climates, attic spaces, and crawlspaces.
- Environmental and indoor air quality: Look for certifications like GREENGUARD Gold, low formaldehyde emissions, and recycled content to minimize indoor pollutants.
- Fire safety and code compliance: Ensure products meet local building codes and ASTM standards. Some reflective barriers also carry fire-rating information (Class A/E84) for permitted installations in specific regions.
- Ease of handling and installation: Softness, rigidity, and cut-ability influence installation speed and material waste. Face materials may aid or hinder stapling and sealing depending on the assembly.
- Hybrid assemblies: For attic fans, ducts, or radiant barrier applications, consider combining unfaced insulation with reflective barriers to optimize both thermal resistance and radiant heat reduction.
- Cost and availability: Compare per-square-foot pricing, width compatibility, and local availability to choose the best value for your project.
When planning an installation, it helps to map your space, determine wall and attic coverage, and identify whether radiant barriers or vapor barriers are needed. The products listed provide a spectrum from standard unfaced-like performance in 23-inch formats to reflective and kraft-faced options that address moisture control and radiant heat. Always follow manufacturer installation guidelines and local building codes for best results.
