Frequently Asked Questions
1. Question:
How
much more do ICF homes cost to build than a conventionally constructed home?
Answer: The
national average says that ICF homes cost approximately 3-5 % more to build
than conventionally constructed homes.
There are, however, many factors that determine the cost incurred to
build any given home. One of the main
reasons that ICF construction is more expensive is that most sub contractors
have no experience in dealing with the system and, therefore, the increase in
cost is generally in labor. We have found
that by using craftsmen who have previously worked with ICF construction we can
actually build ICF homes at about the same cost as conventional construction on
the local level. Material cost is
another very important factor in the cost of building a new home. In the wake of numerous disasters such as
hurricanes and forest fires in the recent past, conventional building materials
price has risen substantially. While
many materials such as lumber have increased in price in recent years, ICF
materials and concrete have remained relatively stable in comparison. This further brings the cost of building a
fundamentally superior ICF home more in line with conventional construction
methods
2. Question: How
does the appearance of an ICF home differ from that of a conventionally
constructed home?
Answer: There
is so little difference in appearance that you may have actually been in an ICF
home and not even known it. There is no difference in the exterior appearance
and the interior only bears one small characteristic that would tell you that
you were in an ICF home. The only
noticeable interior difference is in the window sills – ICF homes have window
sills that are 9-14 inches deep because of the thickness of the exterior
walls. Actually, every ICF homeowner
with whom I have spoken prefers the deep window sills because they provide more
possibilities for window treatments and interior decorating. Our

3. Question: Why
don’t I see more ICF homes on the market?
Answer: That
is a difficult and multi-faceted question to answer, but I will do my
best. ICF construction has been around
for almost 40 years. At first, just as
with any new technology, the cost to build an ICF home was much higher than the
cost to build a conventionally constructed home. Over time, however, ICF building costs have
come down. The majority of the existing
ICF homes are on coastal areas prone to hurricanes because of the strength
offered by ICF construction. While
strength has long been considered the most important advantage to ICF
construction, with energy costs on the rise and resources dwindling daily, the
energy efficiency of ICF homes has become as important, if not more important,
than their strength. Finally, there is
the building industry. The building
industry is hard to change due to the people who work in it. Most builders have been building the same way
for generations and they are pretty set in their ways. Although they can build a better, safer, more
efficient home using ICF construction, most won’t even consider it because it
is new to them. If you lived in another
