Mammoth™ NOVAhush Duct Liner is designed to absorb noise and thermally insulate HVAC ducts. This ensures the reduction of sound transfer along the duct and that air of the desired temperature is delivered at the outlets. Mammoth NOVAhush Duct Liner comes in a plain white sheet or a white sheet with a black face. Independent testing shows that it gives exceptional performance at the low end frequencies (125 – 500 Hertz).
