ICF Advantages For The Homeowner

Greater Comfort & Lower Energy Bills

Energy savings and comfort are built into every ICF system. ICF’s start with a high R-Value. Five inches of polystyrene foam insulation, combine with a six inch concrete wall in an AMVIC 6" ICF system – are rated above R-25 at 75o mean test temperature.


ICF Homeowner Interview Perspectives

Air infiltration in an ICF Home is minimal due to the continuous air barriers provided by the foam insulation and the concrete. Likewise, there are no convection currents within wall cavities.


The concrete walls of an ICF home have high thermal mass, which buffers the interior of a home from the extremes of outdoor temperature during every 24-hour cycle. This reduces both peak and total heating and cooling loads.


This combination of high R-values, low air infiltration, and high thermal mass accounts for the amazing 50% or greater energy savings of ICF versus wood or steel-framed homes. It is suggested that an ICF wall has the thermal effect equivalent to a wood-framed wall built to meet an R-50 standard.


Peace & Quiet

New ICF homeowners almost always remark on how unbelievably quiet their new house is, compared with their old stick-build home. They expect the new-found comfort and energy efficiency, but the peace and quiet – the protection from outside noise – never fails to surprise and delight them.


In sound transmission tests, ICF walls allowed less than one-third as much sound to pass through as do ordinary frame walls filled with fiberglass. With double-glazed windows in ICF walls and beefed-up roof insulation, you will rarely hear street noises or airport traffic.


Solid & Lasting Security

The high-mass walls of an AMVIC ICF home not only give it a remarkably solid feel, but they also make it safer for the family. And make it a remarkably solid and secure investment, too. Concrete homes have a proven track record of withstanding the ravages of hurricanes, tornadoes and fires, when all the stick-build houses around them are in ruins.


In fire wall tests, ICF’s stood exposure to intense flame without structural failure longer than did common frame walls. The polystyrene foam used is treated so it will not support combustion. Also, tests show that its tendency to transmit an outside flame source is less than that of most wood products. [Some insurance carriers are now offering a discount on a home owner’s policy for an ICF home.]


Less Repair & Maintenance

With ICF homes, the equation is simple. No Rot = Less Repair and Maintenance. Neither polystyrene nor concrete will ever rot or rust. Concrete can even be exposed to the elements for centuries with few ill effects. Reinforcing steel, buried deep inside and protected by concrete’s alkalinity, does not corrode.


A Healthier Home & Environment

Building with ICF’s is healthier for the environment in a number of ways: by minimizing the number of different building products involved in construction, by reducing the amount of waste generated on the construction site, and by lowering energy requirements for heating and cooling.


ICF homes provide a healthy indoor environment, too. Nothing held within or ordinarily emitted by an ICF wall is toxic. The measurement of the air contents of actual ICF houses shows an almost complete absence of any emissions.
