It’s a sustainable product that provides superior sound absorbency and fire protection for overall occupant comfort and safety. That’s why AFB® is quickly becoming the insulation of choice for today’s green builders in commercial and industrial construction.  \nAFB® – Acoustically Better  \nSound Transmission Class (STC) values don’t take into account Lower Frequency Sounds (LFS) which can cause vibrations between rooms, negatively affecting the sound environment. The higher density of ROCKWOOL AFB® can reduce sound transmission, helping to create a quiet and comfortable space.  \nSound Control  \nWhen ROCKWOOL AFB® is specified for interior wall or floor assemblies, better overall sound control and fire protection are achieved. Compared to other types of insulation, AFB® provides increased density that effectively reduces airflow and essentially, sound transmissions. Greater noise or sound control is further achieved when thicker AFB® and gypsum board are used together. AFB® thickness ranges from 1.0”  \n(25 mm) to 6”(152 mm) .  \nIn commercial applications, much of the sound to be controlled is in the low frequency or bass ranges. This noise includes conversation, projection/video equipment, mechanical rooms and ventilation systems. In the lower 1/3 octave bands, ROCKWOOL AFB® outperforms glass wool insulation, providing more low frequency absorption when comparing acoustical testing at low frequencies (see chart “Random Incidence Sound Absorption Coefficients, in 1/3 Octave Band”, pg. 3) .  \nRandom Incidence Sound Absorption Coefficients, in 1/3 Octave Band  \n1/3 Octave Band Center Frequency (Hz)  \n65 80 100 125 160 200 250  \nGlass Fiber Sample 1  \nGlass Fiber Sample 2  \nROCKWOOL AFB® Sample 1  \nROCKWOOL AFB® Sample 2  \nGlass Fiber Sample Average  \n3½”  \n3½”  \n3”  \n3”  \n3”  \n0.15 0.15 0.18 0.18  \n0.15  \n0.18 0.17 0.22 0.23  \n0.18  \n0.21 0.19 0.28 0.29  \n0.20  \n0.25 0.22 0.33 0.24  \n0.20  \n0.32028 0.40 0.41  \n0.30  \n0.43 0.37 0.50 0.52  \n0.40  \n0.54 0.48 0.62 0.65  \n0.50  \nROCKWOOL AFB® Sample Average  \n3” 0.18 0.23 0.29 0.34 0.41 0.51 0.64  \n\n|  |  |  |  |  |  |  |  |  |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- |\n\nAcoustical Performance  \n\n| ASTM E 90 | Airborne Sound Transmission Loss | Tested |\n| --- | --- | --- |\n| ASTM E 413 | Rating Sound Insulation | Tested |\n| ASTM C 423 | Sound Absorption Coefficients | Tested |\n| ASTM E 1050 | Impedance and Absorption of Acoustical Materials | Tested |\n\nASTM C423  \nCoefficients at Frequencies  \n\n| Thickness | 125 Hz | 250 Hz | 500 Hz | 1000 Hz | 2000 Hz | 4000 Hz | NRC |\n| --- | --- | --- | --- | --- | --- | --- | --- |\n| 1.0” | 0.14 | 0.25 | 0.65 | 0.90 | 1.01 | 1.01 | 0.70 |\n| 1.5” | 0.18 | 0.44 | 0.94 | 1.04 | 1.02 | 1.03 | 0.85 |\n| 2.0” | 0.28 | 0.60 | 1.09 | 1.09 | 1.05 | 1.07 | 0.95 |\n| 3.0” | 0.52 | 0.96 | 1.18 | 1.07 | 1.05 | 1.05 | 1.05 |\n| 4.0” | 0.86 | 1.11 | 1.20 | 1.07 | 1.08 | 1.07 | 1.10 |\n| 6.0” | 1.11 | 1.28 | 1.15 | 1.06 | 1.03 | 1.01 | 1.15 |\n\nROCKWOOL  \nFeatures and benefits that set AFB® apart.  \nFire Resistant  \nROCKWOOL AFB® is non-combustible and will not develop toxic smoke or promote flame spread, even when directly exposed to fire. AFB® will therefore not add fuel to an existing fire, making it ideal for use in high occupancy buildings. Studies have shown that mineral wool insulated rooms provide a 54% increase in overall fire resistance rating compared to non-insulated rooms. Since stone wool does not contribute to a fire, it can provide valuable extra time for people to reach safety, a critical factor especially in health and education facilities","cbCaibXMwckpL95A","https://ap.wps.com/l/cbCaibXMwckpL95A","pdf",1048661,12,"English","# Acoustical Fire Batt Insulation\n## Sound Control and Performance\n## Features and Benefits","[{\"question\":\"What types of walls and floors is ROCKWOOL AFB® designed for?\",\"answer\":\"ROCKWOOL AFB® is designed for interior wall and floor applications using steel stud and wood stud assemblies.\"},{\"question\":\"How does AFB® help reduce sound between rooms?\",\"answer\":\"AFB® focuses on controlling lower-frequency sounds that can cause vibration, using higher density to reduce sound transmission and improve the overall sound environment.\"},{\"question\":\"What fire performance characteristics are claimed for ROCKWOOL AFB®?\",\"answer\":\"ROCKWOOL AFB® is described as non-combustible, with test results indicating no flame spread or smoke developed in referenced CAN/ULC and ASTM fire-performance standards.\"}]","Acoustical Fire Batt Insulation - ROCKWOOL AFB® | PDF"]
