Acoustic Fiberglass Insulation – 3.5" x 15" x 48" – 110 sq ft

This flexible fiberglass acoustic insulation batt is designed to reduce sound transfer through interior walls, ceilings, and floors. At 3.5" thick and 15" wide, each batt fits standard 2x4 wall cavities without trimming. The sound-absorptive material dampens vibrations before they pass through assemblies, improving acoustic comfort between rooms. It is also permitted for installation within various fire-rated wall, ceiling, and floor assemblies to maintain or achieve a fire resistance rating. Each package covers 110 sq ft, making it a practical choice for residential and light commercial interior framing projects.
