Flexible and easy to install within framed walls or panels, these 6-pack batts provide professional-grade acoustic insulation trusted by recording studios and construction pros. ## Description This is a case of 6 pieces of ROCKWOOL 24 x 48 x 2 inch AFB mineral wool. AFB stands for Acoustical Fire Batts. It is mineral wool at a density of 2.5 pounds per cubic foot. Higher densities absorb sound only slightly better than at 2.5 pcf but cost a lot more, which makes 2.5 pcf the most cost-effective density for absorbing sound. AFB is flexible, like dense household insulation batts. It does not hold it’s shape like rigid fiberglass board (such as ROCKWOOL Rockboard 60). AFB is suitable for acoustic insulation inside walls, building into panels, or any place where there is a frame or structure to support it. In addition to excellent sound absorption, ROCKWOOL AFB mineral wool has a high melting point and is non-combustible, making it suitable for some high-temperature thermal insulation applications. PRODUCT SAFETY INFORMATION - Warning: Can cause respiratory, skin and eye irritation. Precautionary Measures: Avoid breathing fiberglass dust and contact with eyes or skin. Wear long-sleeved, loose fitting clothing, gloves and breathing and eye protection. Review: RV INSULATION - Great for large panels. Perfect for pulling apart and stuffing. USE A BASIC MASK! Review: Effective for sound panels - These make very effective sound deadening panels, and are stiff enough to make construction very easy ## Features - 6 pieces of 24" x 48" x 2" acoustical fire batt mineral wool - It is mineral wool at a density of 2.5 pounds per cubic foot. - AFB acoustic insulation batts are flexible, like dense household insulation batts.
