There are many benefits to using ICFs in the construction of a new home, commercial structure or specialty building

1. Energy Efficient:

One of the primary elements driving modern buildings and appliances is energy efficiency. The standard R-rating of our ICF forms is 27. In a properly constructed building, independent test results have measured as high as R50+. Every year more and more homes are being awarded with the LEED Platinum Rating, the highest rating available today for sustainable building. The ENERGY STAR Qualified Home can attain a 5Star + rating as well. ICF’s contribute significant points towards this prestigious award.

Look at the difference in heat loss between these two homes taken with an infrared camera. One home is constructed with Insulated Concrete Forms, the other is a traditional stick built home. Notice that on the stick built home you can see outline of the 2×6 frame construction where the wall insulation is the weakest. Which home would you rather heat in the winter, or cool in the summer?


2. Sound Insulation

The mass and sound insulating qualities of ICFs cannot be overlooked for occupant comfort and peace of mind. A 2 x 6 wood framed house has 32 ft/lbs of mass for an 8ft wall and a Sound Transmission Class (STC) rating of 32, whereas an ICF wall has 440 ft/lbs and an STC rating as high as 70. With a decibel rating of more than twice conventional framing 49/50 it is easy to see why using this type of construction would be highly desirable.  For some commercial applications, such as apartments, condominiums, hotels or even home theaters where keeping noise from traveling from one residence to another is equally important, ICFs are the logical choice.

3. Comfort

Building comfort is measured by the comparison of the temperature difference between the floor and ceiling. According to ASHRAE, (American Society of Heating, Refrigerating and Air-Conditioning Engineers) "A person’s body may feel thermally neutral as a whole, but may not be very comfortable, if one part of the body is warm and another part is cold.” In buildings constructed of conventional materials, the temperature difference between the floor and ceiling can range from as much as 10 degrees Fahrenheit. By comparison, the temperature difference from floor to ceiling in an ICF building is typically something less than 3 degrees Fahrenheit.

4.  Safety

ICF construction can withstand winds in excess of 200 mph.
They withstand fire up to 4 hours.
They ensure excellent seismic performance.

5. Air Quality

Properly constructed ICF homes and offices have been proven to reduce by at least 75%, the amount of infiltration and leakage found in conventionally constructed buildings. In fact, the reduced air leakage of an ICF home or office, when used in conjunction with properly installed fresh air exchangers and electrostatic air filters, can result in the best possible living environment available for respiratory allergy sufferers.


Benefits of the ICF Building Systems ...

This super insulated concrete building system is energy efficient and cost effective. It is designed to provide benefits for contrac­tors and property owners alike. It can be used above grade as well as below, and is perfect for residential, commercial or industri­al construction.

·       The insulation value of this system has measured as high as R-32 by the thermographic test. Equivalent R values

can exceed 50 due to Thermal Mass Performance.

·        Heating/cooling system size can be reduced as much as 50%.

·        The standard design can withstand sustained winds greater than 160 m.p.h.

·        Construction costs can be less than that of wood or concrete block.

·        The finishing materials used inside and out can be identical to that used with wood frame and masonry construction.

·        These super insulated systems do not support combustion.

·        The walls provide superior soundproofing, with a sound transmission class (STC) rating of 48.

·         This block can be installed at temperatures down to OOE
