Fiberglass insulation board is not used to isolate sound, but to absorb sound. This product used to reduce boundary reflections, control excessive room reverberation, and elminate slap-echo between parallel surfaces for easier listening or recording. Most often used in commercial/industrial assemblies, as well as DIY projects in home theaters, recording studios, and office spaces. Leave this material exposed or wrap it in an acousticall transparent fabric (Guilford of Maine fabric or similar) for a more attractive finish.

INSTALLATION

Acoustic fiberglass board is a great choice for custom installations or DIY acoustics. Our fiberglass insulation boards are easily cut to size with a utility knife or shears and can be mounted into wall or ceilings using perforated base insulation hangers or similar. Wall installations should connect at 5 points (each corner and the center). Ceiling installation should connect at 6 points (each corner and two on the perimeter at the midway point).
