Keep your home comfortable year-round with Owens Corning Kraft-Faced Fiberglass Insulation Batt. Each batt measures 15 in. wide by 93 in. long and 3.5 in. thick, delivering reliable thermal protection where you need it most.
With 13 batts per package, this bundle covers about 125.94 sq ft, making it a practical choice for standard wall cavities and attic spaces where a 3.5 in. thickness is appropriate. The kraft facing provides a convenient built-in facing that supports easy installation and helps with moisture management in typical climate conditions, so you can seal drafts more efficiently.
Why this insulation matters
R-11 thermal resistance reduces heat transfer through walls and ceilings, helping to keep living spaces warmer in winter and cooler in summer. The fiberglass composition is lightweight, easy to handle, and cuts cleanly with a utility knife, allowing for precise fits around framing and obstacles.
