WebOwens Corning® SOFTR® Duct Wrap is a blanket of glass fiber insulation factory-laminated to FRK vapor retarder facing. It is used for external insulation of commercial and residential heating, air-conditioning and dual-temperature ducts. R-Value Ranges: 4.2-8.3. Thickness Ranges: 1.5-3". The noise reduction coefficient (commonly abbreviated NRC) is a single number value ranging from 0.0 to 1.0 that describes the average sound absorption performance of a material. An NRC of 0.0 indicates the object does not attenuate mid-frequency sounds, but rather reflects sound energy. … Meer weergeven The noise reduction coefficient is the arithmetic average, rounded to the nearest multiple of 0.05, of the absorption coefficients for a specific material and mounting condition determined at the octave band … Meer weergeven Mounting type The NRC is highly dependent on the type of mounting, which, if not specified, is usually a Type A mounting (ABPMA mounting #4) where the material is placed directly on the floor, wall, or ceiling.
