Durisol Wall Form systems provide considerable protection against unwanted noise:
STC 54 - 72
NRC 0.70 - 0.95
The sound absorptive properties of Durisol in
combination with the mass of the wall system
provides an ideal combination of sound
absorption and sound transmission properties.
Wall Sound Transmission Coefficient (STC)
ratings can range between 54 and 72, while the Durisol material itself provides Noise Reduction Coefficients (NRC) ratings as high as 0.95.
This means that 95% of the sound that reaches
the Durisol material is absorbed and not reflected back into the airspace.
