Energy Efficiency - The most common sited benefit of ICF wall systems is that it is superior in energy efficiency. Not only does it keep the cold or hot outside air from coming in, it keeps your air conditioned or heated air from going out. Suddenly, your air conditioner and heater barely have to run to keep your interior air at your optimal temperature. What does this mean for you? You can save 50-80% on your energy bill, depending on the doors, windows, roofing, etc.
Strength - ICF wall systems are rated to withstand extreme weather conditions, including tornados and hurricanes. They can endure winds in excess of 140 miles per hour. In addition, they are rated safe for earthquake zones (up to zone 4), as well.
Durability - These walls will not settle, crack, warp, rot, mildew, rust of even vibrate when you slam a door. They do not provide food for insects (like termites, for example), mold, or vermin.
Quiet - ICF wall systems decrease the amount of sound that comes in from the outside by over half. It is the quietest building material on the market.
Comfortable - ICF wall systems result in an even temperature distribution throughout the house from floor to ceiling. There is less than two degrees Fahrenheit variation in an ICF home, compared to conventional homes that vary anywhere from five to ten degrees Fahrenheit. According to ASHRAE (American Society of Heating, Refrigerating, and Air Conditioning Engineers) points to uneven temperature distribution as a leading factor in people feeling uncomfortable. The "feel" of an ICF home is unsurpassed in comfort.
Cleaner Air - ICF systems prevent draft and air infiltration, meaning they prevent airborne contaminants. This is great for a homeowner because not only does it reduce allergens but dust, as well.
Environmentally-Friendly - Aside from it reducing energy consumption due to heating and cooling, it also reduces construction waste. Each and every form will remain on the home or building. There is no construction waste resulting from this system whatsoever aside from the small amounts of packaging. So, not only are they a pleasure to you, but they are a benefit to the environment.
Fire Retardant - ICF systems can resist fires for up to four hours. Even when it starts to burn, the smoke is less toxic than burning wood.
Bullet Proof - Standing behind a concrete wall will shield you from any flying objects, including bullets. Sure, the chances are slim, but this is an added bonus.
Possible Premium Reductions - Many insurance companies offer a premium reduction for homes with ICF system walls.
