Keep your home comfortable year‑round with the Owens Corning 15 in. W x 470 in. L x 6.25 in. Kraft Faced Fiberglass Insulation Roll. This single roll delivers 48.96 square feet of high‑efficiency insulation, designed to help you tighten up walls and attic spaces without adding seams or extra waste.

Why this kraft‑faced fiberglass roll stands out

• R‑19 thermal performance provides solid resistance to heat flow in standard 2x4 framing, helping reduce heating and cooling costs and steadying indoor temperatures.
• Kraft facing functions as a built‑in moisture barrier and gives you a ready‑to‑nail surface for straightforward installation, streamlining your project timeline.
• 1 roll, 48.96 sq ft of coverage means fewer seams and quicker work when insulating longer runs or walls with extended lengths.
• Fiberglass composition offers reliable sound and thermal insulation without added formaldehyde or harsh additives, backed by the Owens Corning name for trusted performance.
• Precisely milled dimensions — 15 in. width, 470 in. length, and 6.25 in. thickness — to fit typical 2x4 construction and provide a snug, efficient fit in tight spaces.

Ideal uses and practical applications

• Insulating interior walls in homes built with 2x4 studs, where space is at a premium and a roll insulation solution fits cleanly.
• Attic floor or crawlspace insulation projects where long rolls reduce joints and speed installation.
• Retrofits and renovations that require a proven, easy‑to‑install insulation option with a built‑in moisture barrier.
• New construction scenarios where crews value a consistent roll format and predictable coverage.

Installation tips for best results

• Install the kraft facing facing toward the interior living space to maintain the moisture barrier and to provide a surface ready for finishing.
• Cut with a utility knife and straightedge; avoid compressing the batt beyond flush with the stud faces to preserve R‑value.
• Secure the roll along studs with staples or recommended fasteners, ensuring there are no gaps around outlets, pipes, or penetrations.
• Wear appropriate protective gear (gloves, long sleeves, mask) during handling and cutting to minimize irritation from fiberglass fibers.
