If you’re a resident of Hawaii and are looking for a stronger, more comfortable, efficient home, we offer you leading edge advanced technology that make this possible.  Our insulating concrete form homes provide you the safety and security you need, along with design flexibility to easily meet any of your custom requirements.

     A recent Insulating Concrete Forms (I. C. F.) home of ours, constructed in the Makiki community, was featured locally on KITV Channel 4.  This report stated that ICF (Insulating Concrete Forms) construction is the new trend in concrete home building in Hawaii.  This featured project may well be the first home in America which boasts a cast in place concrete 4/12 full pitch roof with three different ridge elevations.

The multitude of advantages of Insulating Concrete Forms (ICF) construction are well documented on the web and in building industry literature.  This proven technology has a successful track record that spans over thirty years.  The insulated concrete forms, ICF, method of construction provides cost effective and energy efficient homes.  Expect to save big time on your air conditioning bills.  For instance you will need AC units only half the size required for a typical house.  Furthermore the energy portion of your monthly electric bill will also be cut in about half!  Insulating Concrete Form construction is also one of the most environmentally friendly construction techniques available.  This construction method also results in very quiet and very comfortable living spaces.  On top of all this, these homes are incredibly safe.  There is a documented true story about a house that was hit by a car moving at 90 miles per hour and then shortly afterward it was pounded with 165 mile per hour hurricane gusts with virtually no significant damage.  Since these homes are so more structurally resilient than other house construction, most home owner’s insurance companies will offer discounted rates for ICF house construction.  What is even more amazing is that this house construction is cost competitive with other types of construction.  There is absolutely no question about it, the insulating concrete forms, ICF, construction method is a better way to build homes!

ICF, technique is clearly the winner.  For instance standard timber or wood construction is low cost … but these buildings are not built to last, they have high maintenance costs, and they are vulnerable to termites, rotting, fire, hurricanes, flooding, severe weather and age.  Metal stud construction will not be hurt by termites and it does better with fires, but the metal stud method is still relatively vulnerable to hurricanes, flooding, and tropical weather.  In certain cases, rust can also be a real problem.  Building with concrete, without the insulating forms, results in a expensive water absorbing structure, that can deteriorate more readily over time, the living spaces are uncomfortable and clammy since heat and cold can pass through (it is a bad insulator) and this method hinders the installation of mechanical systems like piping and electrical lines.  The ICF, insulating concrete forms, method of building is nine times stronger, four times more fire resistant, three times more sound resistant, two times more energy efficient, offers nine times greater comfort, it is low maintenance, provides even temperature distribution and offers flexibility in the house’s design.
