Standard mountings include impaling clips with perimeter adhesive, Z-clips, wall bars, concealed kerf/splines, and hook-and-loop. Standard ceiling mountings include wall bar to wall bar or lay-in. Cloud mounting is accomplished with acoustical anchors — eyelet or D-ring — embedded in resin spots on the back. A white fiberglass scrim is recommended for the backs of clouds to eliminate any possibility of airborne migration of particulates.
