Often any higher costs are due to shortages of qualified labor at a particular time in a particular area. Since ICF buildings are so tight, unhealthy indoor air quality can develop. These include curved ICFs as well as the plaster coatings used to finish the pool interior.
Plan 1952
Common configurations of ICF walls and foundations are flat wall, waffle-grid and screen grid. Interestingly, ICF patent-holder Werner Gregori did not foresee the use of insulated concrete forms in residential construction. He initially believed that ICF construction would be too expensive for home builders. However, the cost of lumber and skilled labor rose precipitously in the years following Gregori’s patent application. Today, ICF construction is fairly competitive and can be very affordable, especially when one considers energy savings over time.
Plumbing and Electrical in ICF Construction
When you realize the lifespan of an ICF structure reaches into hundreds of years as opposed to an average of 80 years for a wood structure; the savings really add up. Multiple floors are easy to install using special embedments made specifically for ICF construction. This keeps the floor system inside the envelope eliminating cold and hot spots.

This results in cheaper HVAC equipment and lower energy bills for the entirety of the home’s life. When you couple that with lower maintenance costs and often lower insurance premiums, ICF homes start to make a lot of economical sense. A few years ago, 75 ICF homeowners were surveyed about the features they appreciated most in their ICF homes. It’s no surprise that energy efficiency and disaster resistance topped the list.
ICF homes actually use more and better materials when building the home. While the larger amount of higher grade materials adds to the cost, ICF blocks are so easy to work with that the labor savings are substantial and will help offset the material cost. Of all construction materials, concrete is one of the most fire-resistant materials available which means it makes for a great fire barrier. In fact, ICF walls can attain up to a 4-hour fire rating using a flat wall system.
Our Experience with Heating and Cooling
The ICF forms are simple to cut and shape and may include customized architectural effects, such as curved walls, large openings, long ceiling spans, custom angles, and cathedral ceilings. Common features of a modern ICF house plan include tall and large windows, open floor designs, asymmetrical shapes with unique angles, and flat, multilevel rooflines. Modern insulated concrete form (ICF) homes create energy-efficient, disaster-resistant, and durable houses.
With additional reinforcement appropriate to the level of seismic activity in your area, ICF construction is highly resistant to earthquakes and other shifts. The core also prevents fire by slowing the conduction of heat from one side of the wall to the other. In testing, ICF wall segments didn't allow enough heat through to start a fire on the cool side of the wall for 2 to 4 hours. SPAN TABLES are based on Vibration-Control, this is an important feature for making floors more comfortable for the occupants.
"We have been extremely happy with every step of the process of the design and construction of our home with Jenkins."
Building an ICF home requires qualified professionals that understand the complexities and challenges of constructing an ICF home. A properly built ICF home has a tight building envelope and strong structural integrity. Building an ICF home saves energy, money, and improves the safety and comfort of its occupants.
What Exterior Finishes Can You Use?
Efficiency experts use a blower-door test to determine how drafty a house is, measured in air changes per hour (ACH). The increasing threat of wildfires in California calls for the use of fire-resistant products, like ICFs, in all new construction. Whether you’re looking for a starter home or plenty of room to grow, this 2926-square-foot ICF home plan has everything you need and more. The second story features 4 bedrooms and 4 baths with a void and a multi-purpose family room. ICF walls serve as vapor retardants, and as a result, do not need a vapor barrier.
Now that its benefits become better known, it’s becoming more widely used, especially in areas that are prone to tornadoes or hurricanes (more on that in a bit). There was no difficulty in obtaining financing or special permitting required, as the use of ICFs is an approved building method. The Fox Blocks Series blocks include two pieces of 1.5 pcf density modified two ⅝ inches expanded polystyrene (EPS) foam panels. The panels are locked six to eight inches apart with molded plastic ties made of polypropylene (PP) regrind resin. Fox Blocks is here to make sure you can make your ICF home a reality. Their easy to use Estimator Pro lets you quickly estimate what a project might cost.
Insulated concrete forms use expanded polystyrene foam panels reinforced with steel cables and rebar and filled with concrete, which makes a house extremely strong. On average, you will have to pay between $300,000-$320,000 for a 2,000-square foot insulated form house. Unless you reside in a region with a warmer climate, many home builders use ICF for all concrete construction. Dave Phelps of ICF Homes of Virginia has witnessed similar results in building ICF homes.
For below-grade basement applications with a backfill on a single side, the rebar is typically placed on the tension side of the wall. This application results in higher strength from the pressure of the backfill on the wall. Make sure to follow local codes or site-specific engineering to allow for proper and adequate reinforcement placement. There are two levels defined by building codes to safeguard a structure from water.
Some builders use only insulated concrete foundation forms and combine them with other building methods above ground. This image of a fire ravaged suburb of San Diego with three homes still standing caught his eye. These homes were built with insulating concrete forms and not with wood.
This two-story ICF farmhouse plan is the perfect home for a growing family. The first floor features a kitchen, utility room, dining room, living room, 1 bathroom, an office, shop, and garage. It is also important to remember that the amount of time required to compile all of the necessary permits for an ICF home will likely take longer than for a conventional home. Since this is not the standard in the residential construction industry, the permitting process can be a bit more arduous.
