ECHO Acoustic Panels

Type ECHO acoustic panels are fabricated of various thicknesses and materials depending
on the level of noise control required for a particular application. ECHO Acoustic panels are fabricated
with an outer solid shell of 0.5 – 1 mm and inner perforated shell of 0.5 mm stainless steel. Panels are stiffened with 1 mm gage internal channels and edge rails. The acoustic grade fill is long strand fiberglass or mineral wool or ArmaSound orArmaPhonic elastomeric sound absorber product, depending on the application, are inert, mildew resistant, vermin proof and incombustible. Standard panels are 4″ thick, but optional 2″ and 6″ panels are available to meet special requirements
