Kraft facing plus Next Gen recovery and shed-resistant handling
Technical specifications
| R-Value | 11.0 |
|---|---|
| Thickness | 3.5 in |
| Width | 15.0 in |
| Length | 93.0 in |
| Coverage | 125.94 sq ft/pack |
| Material | Fiberglass (PINK Next Gen) with kraft vapor-retarder facing |
| Fire rating | ASTM C665 Type I; glass fibers ASTM E136 noncombustible when unfaced. Kraft facing is combustible—install per OC facing exposure rules. |
| Sound rating | Cavity-fill fiberglass improves typical wall STC versus an empty cavity; final acoustic performance is assembly-dependent. |
| Density | Light-density flexible batt per ASTM C665 manufacturer Type I listings |
| Thermal conductivity | Nominal R-11 at full labeled thickness; see manufacturer TDS for tested values |
| Framing width | Sized for nominal 2×4 walls at 16 in. on-center stud spacing (15 in. wide batt) |
| Construction type | Wood-frame and light-gauge metal-frame cavity construction |
| Application area | Wood-framed walls, floors, and roof/ceilings; metal-framed walls and floors; interior side of basement and unvented crawlspace walls where approved by code |
Product details
About 125.94 square feet per package (IDI-listed coverage for BF01). Primary use: exterior or interior 2×4 walls framed 16 in. on center where R-11 satisfies the modeled cavity and kraft facing is part of an approved interior-side vapor-retarder approach.
R-11 batts still appear in remodels, climate zones with modest cavity targets, and phased upgrades where the assembly is not yet ready for higher-R packages. BF01 pairs the classic 15 in. × 93 in. module with distributor-documented high bag coverage so multifamily corridors and production builders move fewer pallets per insulated square foot.
Owens Corning documents ASTM C665 manufacturing, Title 24 Article 3 insulating-material alignment, GREENGUARD certification with formaldehyde-free validation, and UL Environment EPD reporting. Kraft facings must remain covered and are listed for ICC construction types III–V.
Use the BF01 technical data sheet (IDI SKU 1010103) for packaging counts and installation references. Maintain full labeled thickness, align insulation with the air barrier, and treat penetrations as part of the tested assembly.

Frequently asked questions
BF01 vs BF107—are they the same product family?
BF01 vs BF107—are they the same product family?
They are different catalog SKUs with different R-values, dimensions, and coverage. Always match the model on your purchase order to the data sheet for the exact item specified on drawings.
Is 125.94 sq ft the bid number?
Is 125.94 sq ft the bid number?
That is the IDI-published package coverage for BF01. Confirm the same value on the physical bag label before you translate packages to contract square footage.
Can I double R-11 batts to reach a higher R-value?
Can I double R-11 batts to reach a higher R-value?
Layering changes thickness, density, and sometimes fire or ventilation requirements. Follow an engineer- or code-approved detail rather than stacking batts ad hoc.
Does kraft facing control sound?
Does kraft facing control sound?
STC is dominated by mass, openings, and airtightness. Kraft adds vapor-retarder function; it is not a standalone acoustic upgrade—detail the full tested assembly.
