This is a single precut fiberglass batt, 15 inches wide by 93 inches long, rated R-13 for 2x4 wood-framed walls. The kraft facing acts as a built-in vapor barrier for exterior walls and adds some sound control. It is formaldehyde-free and sized for standard 8-foot walls with 16-inch on-center studs. It suits DIYers insulating or topping up exterior wall cavities; compared with unfaced batts it saves a separate vapor barrier step, but it is not for below-grade or wet areas where a kraft facing can trap moisture.

This is a kraft-faced fiberglass batt insulation for 2x4 wood-framed walls. It is formaldehyde-free and provides thermal and acoustical insulation. The kraft facing works as a built-in vapor barrier for moisture control in exterior walls.
The batts are precut for standard 8-ft walls with studs spaced 16 in on center. They are compression-packaged to save space and can be used in vertical and horizontal applications. To install, press the batt in place between the studs. Staple the tabs to the framing if more securement is needed.
The insulation improves energy efficiency and reduces sound transmission through walls, ceilings and floors. It will not rot, mildew or deteriorate. It is noncorrosive to pipes, wiring and metal studs.
