Primacoustic’s new Paintables absorptive clouds include the circular Cirrus, hexagonal Hexus and square Altos, each in 36-inch and 48-inch diameters. Each panel is made from 1-1/2-inch thick high-density six-pound glass wool with resin-hardened edges with micromesh that fully wraps the panel.

All Paintables are factory painted in Absolute White latex; their proprietary surface reportedly enables users to lightly spray paint the panels on-site to color match any decor without affecting the acoustical performance.
