Durisol ICF 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.
More information is available in our Technical Guide.

The Durisol ICF wall system has a 4 hour fire rating.
The surface burning characteristics of Durisol far
surpass all other types of ICF products.Dursiol
has a flame spread and smoke spread rating
of zero. Unlike foam, Durisol will not ignite, melt, sustain fire or release toxic smoke in the event
of a fire.
- Over 4 hour Fire Resistance Rating
- 0 Flame Spread
- 11 Smoke Spread
- 0 Fuel Contributed to fire.
Test Reports are available upon request.

Standard stuccos applied directly to the Durisol ICF substrate result in a finish that is less expensive and more impact resistant than conventional EIFS systems (polystyrene and stucco). Detailed information regarding the use of stuccos and other finishes with the Durisol wall system are contained in the
Technical Guide.

While the Durisol ICF material is inert with no VOCs or off-gasing, the cement content of the Durisol material creates an above average pH environment at the wall surface , that inhibits the growth of fungi and mold. Furthermore, the hygroscopic nature of the material moderates relative humidity levels (65% RH maximum) and provides an inherent moisture regulator that keeps humidity low and further serves to repress any type of fungal growth.

Unlike wood and other non-hygroscopic material, Durisol ICF provides effective resistance to termite attack. A number of testing programs have been conducted by independant agencies such as the U.S. Forestry Service. Durisol samples were placed in termite infested areas for as long as six years without any destruction of the Durisol material.
