Large ~88 sq ft package coverage for high-production attic and floor jobs
Key features
24 in. width for full-bay coverage on 24 in. o.c. framing
Kraft facing for coordinated vapor-retarder strategies when allowed
Technical specifications
| R-Value | 30.0 |
|---|---|
| Thickness | 10.0 in |
| Width | 24.0 in |
| Length | 48.0 in |
| Coverage | 88.0 sq ft/pack |
| Material | Fiberglass (PINK Next Gen), kraft-faced |
| Fire rating | ASTM C665 Type I; glass fibers ASTM E136 noncombustible when unfaced. Kraft facing is combustible—follow OC guidance for ICC construction types and rated assemblies. |
| Sound rating | Cavity-fill fiberglass improves typical assembly STC versus an empty cavity; final acoustic performance is assembly-dependent. |
| Density | Light-density flexible batt per ASTM C665 manufacturer listings; see TDS for product-specific values. |
| Thermal conductivity | Nominal R-value at labeled thickness; see manufacturer TDS (ASTM C518) for tested conductivity. |
| Framing width | 24 in. width for 24 in. on-center framing modules |
| Construction type | Wood-frame and light-gauge metal-frame cavity construction |
| Application area | Attics, floors, and roof/ceilings; wood- and metal-framed cavities per code and Owens Corning literature. |
Product details
About 88 square feet per package (IDI-listed coverage). Primary use: 24 in. on-center attics, floors above garages or crawlspaces, and compatible ceilings where kraft-faced R-30 batts match the bay and the energy target.
E56 lists 10 in. labeled thickness, 24 in. width, and 48 in. length on IDI Insulation. The 24 in. width is intended to blanket a 24 in. module in one piece, which reduces center seams compared with forcing narrower batts into wide bays. Kraft facing supplies a vapor-retarder layer on the appropriate side of the assembly when your hygrothermal plan uses Class I interior retarders—verify orientation against IECC and local amendments before production rates lock in the wrong facing direction.
IDI’s marketing copy for this SKU references GREENGUARD Gold certification and high recycled content with wind-powered manufacturing claims at the distributor level. Field teams should still emphasize full thickness, continuous soffit-to-ridge vent channels in vented attics, and thermal-barrier coverage over facing because kraft is combustible.
Bag weight and volume jump with 88 square feet per package—coordinate hoist paths, attic hatches, and in-unit staging like other jumbo attic packs. Use the PINK Next Gen Fiberglas insulation product data sheet linked from IDI for authoritative tested values and code language.

Frequently asked questions
Why is E56 coverage higher than ME24?
Why is E56 coverage higher than ME24?
Width and packaging differ. E56 is distributor-listed at 24 in. wide with about 88 square feet per package; ME24 is 16 in. wide with about 58.67 square feet per package per IDI.
Is E56 too heavy for residential attic hatches?
Is E56 too heavy for residential attic hatches?
Large bags are heavier—plan crew size, ladders, and protected walkways. Always follow jobsite lifting guidance.

Can I compress E56 under boards for storage?
Can I compress E56 under boards for storage?
Compression lowers effective R-value for fiberglass. Preserve thickness or redesign the storage detail.
