Owens Corning R-19 Faced Fiberglass Roll 23″ Wide
Product overview: This faced roll insulation measures 23 inches in width and extends about 39.2 feet in length. Designed for 2×6 walls, it also suits floors, crawlspaces, and attics. The roll provides strong thermal control and effective acoustical performance while aiming to produce less dust than other fiberglass products. It integrates with standard kraft-backed facings and features a balance of stiffness and recovery characteristics that help with easier handling during installation.
Owens Corning 853 SQFT R-19 Kraft Faced Batt (16×96)
Product overview: This bundle provides 853 square feet of kraft-faced R-19 fiberglass batt insulation across ten bags (as two bundles of five). The product is sized for 2×6 exterior walls and comes with a value-focused offering, including the possibility of a discount for pickup at specified warehouses. The kraft facing serves as a moisture and vapor barrier, contributing to easier exterior wall installations and improved air control in interior spaces.
Owens Corning R-19 Faced 23×48 Batt Insulation
Product overview: This kraft-faced batt insulation covers 23×48 inches and is designed for 2×6 floors or walls. The bundle typically includes ten bags (2 bundles of five), delivering a total of 1280 square feet of coverage. The kraft facing provides a temporary moisture barrier, aiding in exterior applications and interior installations that require controlled moisture transfer. The product is suitable for interior use where moisture exposure is a consideration.
EcoRoll Kraft R-19 23 Inch Wide Faced Roll
Product overview: This kraft-faced fiberglass insulation roll measures 23 inches wide and 39.2 feet long, totaling about 75 square feet per roll. It carries GREENGUARD Gold certification and is formulated to be free of red-list chemicals and formaldehyde, with a natural, eco-friendly binder. The finish is softer to the touch, making it easier to cut and install, while the kraft facing provides moisture control suitable for interior applications and light exterior use where appropriate.
Owens Corning 775 SQFT R-19 Unfaced Batt
Product overview: Unfaced batt insulation designed for interior applications where a separate moisture barrier is installed separately. This product provides a total of 775 square feet across ten bags (two bundles of five). It is suitable for interior walls, floors, ceilings, and attic spaces with adequate ventilation. The absence of facing eliminates potential moisture bias in areas where a dedicated vapor barrier or air barrier is used elsewhere in the assembly.
JOHNS MANVILLE 1337 SQFT R-19 Unfaced Batt
Product overview: This unfaced insulation option provides 1337 square feet across ten bags, suitable for 2×6 floor-ceiling assemblies. Being unfaced, it requires a separate moisture barrier or air sealing strategy as part of the building envelope. The product is designed for interior applications where an undisturbed airflow and vapor management plan are in place, making it a versatile choice for multi-story homes and spaces with complex framing.
2 Pack Owens Corning R-13 Pink Kraft Faced Roll
Product overview: While labeled as R-13, this insulated roll setup is highlighted for exterior/interior 2×4 wall installs and can complement R-19 projects when layered or used in adjoining assemblies. It helps maintain temperatures and reduces noise transmission. This product offers a convenient roll format and is designed to be soft to the touch, with a formaldehyde-free composition consistent with modern manufacturing standards.
SmartSHIELD -5mm 16″ x50ft R15 Reflective Foam Core Roll
Product overview: This product combines insulation with a radiant barrier, projecting reflective performance to reduce radiant heat gain. It claims high effectiveness by reflecting up to 95% of radiant energy, providing an R15 equivalent value in a compact, all-in-one package. It can function as a radiant barrier, vapor barrier, and sound barrier, offering a versatile solution in mixed climate zones where space is at a premium.
Buying Guide
Key purchase considerations for R-19 batt insulation include the following:
- Framing type and space: Most R-19 batts are designed for 2×6 walls. Verify your wall dimensions and ensure the batt width matches your stud spacing to minimize gaps and compression.
- Facing vs unfaced: Faced batts include a kraft or foil facing that serves as a moisture or vapor barrier in some assemblies. Unfaced batts require an alternative barrier or air sealing plan. Consider local building codes and climate conditions when choosing.
- Moisture concerns: In areas with high humidity or potential moisture exposure, kraft-faced batts may offer moisture control advantages, but dedicated vapor barriers or exterior drainage must be planned.
- Eco considerations: Some products advertise GREENGUARD Gold certification or formaldehyde-free formulations, contributing to indoor air quality and environmental impact considerations.
- Installation ease: Roll formats can be quicker for large, rectangular spaces, while batts with higher stiffness recover well after installation and resist sagging over time.
- Acoustic performance: Fiberglass batts typically provide noise reduction in addition to thermal insulation. For rooms with higher sound transmission, look for products designed with improved acoustical control.
- Cost vs value: While not mentioning prices, consider long-term energy savings and installation efficiency as part of the decision, especially when choosing between faced and unfaced options or between standard batts and radiant barrier combinations.
- Code compliance: Always ensure chosen products meet local building codes and meet R-19 requirements for your target climate zone and wall construction.
Multiple perspectives are reflected in the product lineup: faced batts for straightforward moisture management in standard wall assemblies, unfaced batts for assemblies with dedicated moisture barriers, and roll formats for fast coverage in larger areas. Radiant barrier products add a different dimension by targeting radiant heat transfer, which may be beneficial in hot climates or retrofit projects where space is limited.
