Designed to provide stronger, more comfortable, quiet and highly energy-efficient structures. It shall be apparent to the Rater that the exempted areas are intentional designed details or the exempted area shall be documented in a plan provided by the builder, architect, or engineer. The Rater need not evaluate the necessity of the designed detail to certify the home. A flat ICF wall system is a solid concrete wall of uniform thickness with sheets of insulation forming the interior and exterior surfaces of the system.

In addition the 30-70% savings in energy costs and consumption offsets some of the first costs required to build an ICF home. ICF walls are high-quality and ICF homes require small mechanical systems. These both contribute to lower monthly operational costs to the homeowner.
Reduce Building Steps with an ICF Wall System
We noted in previous posts that the Element Homes team has years of experience working with California homeowners to protect their properties from earthquakes, floods and wildfires. Our staff not only understands the ins and outs of ICF construction, but is also well-educated in all California building codes -- even the newest energy standards. Schedule a consultation with our design-build team or learn more about our process by filling in the form here. California homeowners who choose ICF construction can expect impressive cost savings -- even during the summer and winter when external temperatures are extreme. The ties that interconnect the two layers of insulated forming material can be plastic, metal, or additional projections of the insulation. There are advantages to each type of material, but one current trend incorporates hinges into the ties that allow pre assembled forms to fold flat for easy, less costly shipping.
Energy Comparison of ICF vs. Wood-Frame Homes
The forms are insulated on the inside and the outside, providing high level of wall insulation uncommon in standard home construction. Because the ICF blocks fit together virtually seamlessly, there is very little air infiltration, increasing the effective insulation value. Exterior walls are built using the forms, which go together like Lego blocks, the steel is placed in the built-in slots inside the ICF blocks, and then they’re filled with concrete. ICF blocks are usually 96 inches long and 16 inches high, but they come in varying shapes and sizes to accommodate corners and other needs. An independent study conducted by CLEB Lab concluded that an ICF wall provided 58% greater R-value and 43% energy-savings compared to the wood-frame wall. Rastra walls, made from rastra blocks, are an innovative alternative to conventional construction materials.
WHAT CAN I BUILD WITH BUILDBLOCK INSULATING CONCRETE FORMS?
The popularity of building homes with Insulated Concrete Forms (ICF) is surging. Of course, for home builders, erecting forms and pouring concrete walls is nothing new, at least below grade. But the advent of lightweight, stackable, interlocking forms that also incorporate interior and exterior insulation has opened the market for ICF for virtually all exterior wall applications.

However, there are significant savings realized from using ICF, and that will be discussed later. The ICF construction of this home makes it incredibly energy-efficient and durable. With its spacious and open layout, this floorplan is perfect for families who love having friends and family around.
Completed Projects and counting
Historically most commonly used for foundation walls, many builders are now taking ICF further and using them for above-grade walls of 1, 2, and 3 story homes. One of the primary reasons we chose Insulated Concrete Form construction was for its energy efficiency. Because the walls are uniformly insulated with a solid sheet of foam inside and out, there are no channels for air to seep through.
The reinforced concrete adds thermal mass for buffering excessive temperatures and provides additional resistance to strong winds, storms, and fire. Insulated Concrete Form, or ICF house plans provide a solid, long-lasting home that resists fire, wind and time. Better than even plain concrete block walls, house plans with ICF walls give two built-in layers of foam insulation for added energy efficiency.
ICF Construction: Everything You Need To Know
It will melt if exposed to high heat, but it will not contribute any fuel to the fire. In fact, it is virtually “self-extinguishing,” thanks to a flame retardant all of the leading ICF manufacturers add to the EPS foam. When a raging wildfire swept through the suburbs of San Diego in the fall of 2007, it forced more than half a million people from their homes and destroyed more than 2,000 residences. Still, many experts believe ICFs are the most cost-effective—and aesthetically pleasing—way to protect occupants and their belongings from natural disasters. Efficiency experts use a blower-door test to determine how drafty a house is, measured in air changes per hour (ACH). Due to increased overall dimensions, the roof system will be bigger for an ICF home.
The construction involved with building ICF walls is meant to create a long-lasting product. Resistant to mold, mildew, rust, rot, etc. equals less repair and maintenance fees. Further cost-savings is experienced from the minimal long-term maintenance requirements of an ICF home. ICF walls require about 44% less energy to heat and 32% less energy to cool than similar frame houses.
These homes perform well in flooding, so they are appropriate for coastal areas. The reinforced concrete also makes them suitable for highly seismic zones. If you live in an area prone to natural disasters, an ICF home could give you peace of mind.

Are you building multiple projects, large commercial projects, developing multifamily housing, schools, or other structures? Connect with the resources and information you need to astound your customers and make your next ICF project a success.
If additional steps are taken, such as adequate attic insulation, quality windows and doors, and a properly-sized high-efficiency HVAC system, the savings could be even more. EPS foam, from which ICFs are made from, is one of the best insulating materials yet invented. Imagine a disposable foam cup, where 1/8 inch of EPS foam is all it takes to comfortably separate your hand from a scalding drink.
BuildBlock designs products that naturally work together and eliminate the need for costly accessories such as clips or zip ties. The unique web design allows for better concrete flow and improved strength, and superior service, training, and support ensure you can make your project a success. Home plans using ICF can be designed to reflect an assortment of features. An open floor plan, two master suites, a walk-out basement, a wraparound porch, a fireplace, etc. are all popular features. Aware of the value of an ICF structure in hurricane prone areas of Florida, insurance companies increasingly encourage these types of homes by offering rate reductions.
