Aluminum outer shell—extremely lightweight and rustproof means easy hanging or fan attachment.
Glass fiber instead of acoustical foam —glass fiber has a Noise Reduction Coefficient (NRC) of 85% versus 50% for foam.
End flanges with inner taper of 45 degrees versus a flat 90 degrees with other brands to further eliminate sound. The inner taper of the flanges helps prevent sound waves from escaping.
Inner mesh holding with expansive open-air perforations—allows the maximum amount of sound waves to enter the thick bed of glass fiber where the sound is transformed into heat as it passes through each glass fiber.
Comes in large and mini sizes—mini sizes give you an option in a tight space where you don’t have enough room for the standard size, and are twice as Phat as the standard models, giving you more sound attenuation in a small package.
