R-22-class performance in nominal 2x8-depth assemblies for stronger cavity R than R-19 stock
Key features
23 in. width for 24 in. o.c. bays with predictable edge contact in production framing
48 in. module for easier handling in floor systems and stacked multifamily construction
Technical specifications
| R-Value | 22.0 |
|---|---|
| Thickness | 6.75 in |
| Width | 23.0 in |
| Length | 48.0 in |
| Coverage | 107.34 sq ft/pack |
| Material | Fiberglass (Owens Corning PINK Next Gen™ Fiberglas®, unfaced) |
| Fire rating | ASTM C665 Type I; glass (unfaced) classified noncombustible per ASTM E136. Coordinate rated assemblies with your AHJ when combining with facings, membranes, or foam. |
| Sound rating | Unfaced cavity-fill fiberglass improves typical assembly acoustics versus an empty cavity; field STC depends on framing, openings, and flanking paths. |
| Density | R-22 preformed batt; supplier part 111782 per IDI / Owens Corning listings |
| Thermal conductivity | Nominal R-value at full labeled thickness; see manufacturer TDS for tested thermal values. |
| Framing width | 23 in. width for nominal 24 in. on-center framing in nominal 2×8-depth cavities |
| Construction type | Wood-frame and light-gauge metal-frame cavity construction |
| Application area | Wood- or metal-framed floors, ceilings, and roof decks in nominal 2×8-depth cavities on 24 in. o.c.; coordinate vapor and air control with designer |
Product details
U23 is what you reach for when the energy model wants more than R-19 in a nominal 2×8-depth cavity but you still want manageable 48 in. lengths for floor bands, platform framing, or modular pods where 96 in. stock is awkward to maneuver. The 23 in. width targets 24 in. on-center modules with a bit less lateral squeeze than full-width batts when framing tolerances stack, while roughly 107.34 square feet per package (IDI) anchors takeoffs for podium decks and multifamily corridors.
Unfaced fiberglass preserves flexibility for crawlspace ground contact details, hybrid rim assemblies, and coordinated polyethylene or smart-membrane strategies without default kraft on the warm side. Documentation follows PINK Next Gen norms: ASTM C665 manufacturing, ASTM E136 noncombustibility for unfaced glass, Title 24 Article 3 language, GREENGUARD validation, and EPD references.
Quality still hinges on execution: stagger joints per manufacturer guidance, keep batts dry before install, and avoid crushing at rim channels where thermal bridging and air leakage penalties show up first in diagnostics.

Frequently asked questions
Is 48 in. length enough for my floor joist layout?
Is 48 in. length enough for my floor joist layout?
48 in. batts suit common joist spacing with staggered joints per manufacturer guidance; verify bay lengths and splice pattern on your plans.
Can I leave this exposed in a crawlspace?
Can I leave this exposed in a crawlspace?
Exposed use depends on code and assembly; many crawlspaces require a protective covering or ignition barrier—confirm with your AHJ.
Does R-19 in a 2x8 floor meet my local code?
Does R-19 in a 2x8 floor meet my local code?
Prescriptive R-values vary by climate zone and project type; compare published cavity R to your jurisdiction’s table or modeled performance path.
