Designed to improve the sound quality in a room by absorbing sound echoes and reverberation. Audimute panels are composed of eco-C-tex, which is Audimute's recycled sound absorption material that is effective, non-toxic, and requires less energy to produce than traditional fiberglass and foam acoustic products. The surface of each panel is a graphic printed on acoustical fabric. Each size contains (40) 1"x2" pieces of double sided 3M tape. We recommend using 2 pieces of tape on each panel, one centered on the top and another centered on the bottom. Cleaning Instructions: Clean with water based cleaning agents, foam or pure, water free solvents. Vacuuming or light brushing is recommended to prevent dust and soil buildup. Note: Due to the variations in recycled material, the eco-C-tex sides of each panel may vary in color tones, but will typically have a neutral speckled light grey appearance. Features: Designed for sound absorption, NOT sound blocking. Lab tested - 0.55 NRC Rating High-quality, durable, safe for your health, & "green" Fire safe materials - class A fire rated (ASTM E-84).
