What is this ICF everyone is talking about?
ICF stands for Insulating or Insulated Concrete Forms. These are 2 to 4 inch insulation forms on each side of middle used to build the outside walls of homes or buildings, as well as metal bars in the middle for strengthening the concrete that will be poured into the forms. The forms are mainly used for the exterior walls, which then have the traditional finish of brick, rock, stone, etc. applied, making the home look like all others except for the thickness of the outside walls.
Benefits of building ICF
Superior Energy Efficiency – By keeping the cold or hot outside air from coming in, and keeping your air conditioned or heated air from going out. Your air conditioner and heater won’t have to run as much so your inside temperature will be optimal. This results in typical energy savings of about 50-80% depending on your doors, windows and roofing.
Extreme Weather Resistant – ICF wall systems are rated to withstand extreme weather conditions, including tornadoes and hurricanes. They can endure winds in excess of 140 miles per hour, and are also rated safe for earthquake zones.
Durability – Settlement, cracking, rotting, mildew, and rusting are not a problem for ICF homes. Nor do they provide food for insects, mold, or furry little creatures of the field.
Noise Reduction – Outside noises are decreased by over half because of the insulated wall thickness.
Even Temperature Distribution – ICF wall systems have 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. You just get a more comfortable feeling with the even distribution.
Allergen/Dust Reduction – ICF systems prevent draft and air infiltration, so they prevent airborne contaminants. This is great because it is an allergen as well as dust remover.
Fire Resistant – And how about ICF walls being fire resistant. This could result in insurance companies offering premium reductions. Check with your insurance company.
