Choosing superior, environmentally friendly materials likeNexcem ICF insulated concrete formsfor your design will guarantee that your building will endure for generations, while having minimal impact on the environment around us.
Nexcem Insulated Concrete Form ICF Comparison
When designers and builders make cost-effective and technically superior decisions in a manner that is environmentally responsible, they are providing the best design solution for both the owner and the environment
ICF Performance Benefits
- Fireproof (4 hr Fire Rating, 0 Smoke Spread, 0 Flame Spread)
- Moisture Resistant
- Promotes Healthy Interiors (breathable / inhibits mold)
- More Energy Efficient (Insulation on Exterior of Thermal Mass)
- Impact Resistant
- Termite/Vermin Proof
Please click on the following link for a detailed comparison of Nexcem vs other ICF systems:
STC 54 – 72 andNRC 0.70 – 0.95
The sound absorptive properties of Nexcemincombination with the mass of the wall systemprovides an ideal combination of soundabsorption and sound transmission properties.Wall Sound Transmission Coefficient (STC)ratings can range between 54 and 72, while the Nexcemmaterial itself provides Noise Reduction Coefficients (NRC) ratings as high as 0.95.This means that 95% of the sound that reachesthe Nexcemmaterial is absorbed and not reflected back into the airspace.
More information is available in our Technical Guide.
The Nexcem ICF wall system has a 4 hour fire rating.The surface burning characteristics of Nexcemfarsurpass all other types of ICF products. Nexcem has a flame spread and smoke spread ratingof zero. Unlike foam, Nexcemwill not ignite, melt, sustain fire or release toxic smoke in the eventof 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 NexcemICF 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 stuccosand other finishes with the Nexcem wall system are contained in the Technical Guide.
While the NexcemICF material is inert with no VOCs or off-gasing, the cement content of the Nexcemmaterial 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, NexcemICF provides effective resistance to termite attack. A number of testing programs have been conducted by independant agencies such as the U.S. Forestry Service. Nexcemsamples were placed in termite infested areas for as long as six years without any destruction of the Nexcemmaterial.
