An acoustic ceiling cloud has two possible thicknesses, 1 in. or 2 in. Options like our AcoustiCloud are only available in a 1 in. thickness, while others like the Anchorage and Whisper Ceiling clouds come in both thicknesses. The best thickness for your space will depend on the noise level you are trying to control. A thicker panel is ideal for noisier environments for more effective sound absorption.
