Product details
About 118.83 square feet per package (IDI-listed coverage). Primary use: 24 in. on-center wood-framed walls, floors, and ceilings where kraft-faced R-19 batts match the wider stud module and the energy target.
E54 lists 6.5 in. labeled thickness, 23 in. width, and 93 in. length on IDI Insulation. The 23 in. width is intended to fill 24 in. on-center bays in one piece, which reduces center seams compared with forcing 16 in. batts into a 24 in. module. Kraft facing integrates a vapor-retarder layer—orient it per IECC, IRC, local amendments, and your drawings, especially when exterior continuous insulation changes winter moisture drive.
IDI markets GREENGUARD Gold certification and recycled-content messaging for this listing. Logistics matter: large square-foot packages are heavier—plan crew size, ladders, and protected walkways like other high-coverage batt lines.
Use the PINK Next Gen Fiberglas insulation product data sheet linked from IDI for tested properties and code references. When comparing to M50 unfaced at 24 × 96 in., remember length, facing, and listed coverage all differ—bid with the exact SKU attached to purchase orders.

Frequently asked questions
E54 versus M50 unfaced at 24 in. width?
E54 versus M50 unfaced at 24 in. width?
M50 is distributor-listed at 24 × 96 in. unfaced with about 128 square feet per package; E54 is 23 × 93 in. kraft-faced with about 118.83 square feet per package per IDI. Dimensions, facing, and coverage all differ.
Why 23 in. width instead of 24 in. for 24 in. o.c.?
Why 23 in. width instead of 24 in. for 24 in. o.c.?
Owens Corning sizes this SKU to the listed 23 in. width per IDI for the 24 in. module—field-verify clear bay width before truck counts.
How many bags for my job?
How many bags for my job?
Divide net insulated area by about 118.83 square feet per package and add a waste factor for openings and cuts.
Is kraft facing an air barrier?
Is kraft facing an air barrier?
No. Treat kraft primarily as a vapor retarder and facing layer; design and seal your air barrier system separately.
