This R14 mineral wool batt insulation is designed for thermal resistance in both wood and steel framing applications. Each batt measures 3.5" x 16.25" x 48", fitting standard 2x4 steel stud cavities with precision. A single package covers 65 square feet, making it well suited for exterior walls, basements, and crawlspaces. Mineral wool construction provides natural water repellency and fire resistance, and the batts compress and recover easily for a snug, gap-free fit. Reliable thermal performance for both DIY renovators and professional contractors.
