Are you thinking about using insulated concrete forms (ICF) to build your new home? We’ll cover what ICF is, how it works, and the pros and cons of ICF construction. Here’s what you need to know about this energy-efficient building material.
Pros and Cons of Building ICF Homes in California
Other homes in the neighborhood were completely consumed by flames, but this one, built with ICF, survived. This home built with Insulated Concrete Forms narrowly escaped destruction in 2018’s California’s wildfires, which burned 18,804 structures and took 85 lives.
Plan: #132-1307
The screen-grid ICF wall system is similar to a waffle-grid ICF wall system without concrete webs in between the vertical and horizontal members. The post and beam ICF wall system has vertical and/or horizontal concrete members spaced farther than 12 inches on center. Dave Phelps of ICF Homes of Virginia has witnessed similar results in building ICF homes. ICF construction has two advantages in terms of the energy performance of the building. First, it seals very well, preventing air leakage through the walls.
Reduce Building Steps with an ICF Wall System
Steel rebar is added to the cavities for additional strength (Figure 2). Some ICFs come with plastic nailing strips embedded in their exterior surfaces. Some ICF products use extruded polystyrene (XPS) foam, which is stronger but more costly. Some ICF walls consist of two layers of concrete sandwiching a central layer of foam. Concrete block and ICF (insulated concrete form) house plans offer a number of advantages – like improved energy efficiency – for the eco-conscious homeowner.

The foam forms stay in place, providing permanent insulating foam layers on the interior and exterior of the wall. Foam blocks are typically comprised of two 2-inch-thick, 16 by 48-inch rectangles of foam that are connected by plastic, metal, or foam ties. The ties hold the foam panels 6 or 8 inches apart during the pour and remain in place afterward. The blocks are stacked like bricks to create the wall forms for the concrete.

That’s because ICF saves steps in both the exterior and interior construction. Also, one of the most time-consuming and yet important aspects of wood framing are all the many steps required to protect a wood frame from moisture. So there are dual-layer and even triple-layer protection systems involved in protecting a wood frame from moisture. Plus, the ICF system is designed to allow moisture to exit the frame inherently.

ICF homes offer a level of safety no other building system can match. They are more than 10 times stronger than framed structures, and several times stronger than CMU “cinder block” construction as well. It’s a natural result of having exterior walls with a core of solid, steel-reinforced concrete. Architects can design an ICF home to look just like a wood-frame house and still take advantage of all the added benefits of building with concrete. The floor plan can match virtually any style, and ICFs are compatible with all popular interior and exterior finishes.
Any scraps with at least one web can be integrated into the wall without sacrificing strength. The 1″ repeating pattern lets you cut off as little as 1″ and still be able to fully interlock the block in a wall. BuildBlock manufactures a complete ICF solution for projects of any size or complexity. Form sizes from 4″-12″+, floor and roof decking, bucking, and more.
If you have a home with an extremely tight building envelope, you will likely experience more considerable savings. While you will probably pay 5% - 10% more upfront for an ICF home, your energy bills will be lower each month than if you were to build a wood-frame home built to typical standards. I would not recommend do it yourself ICF construction for the average handy person. It can be done, but you need special equipment and you don't want to screw up.
Our expert team will work with you, give you the knowledge and support that you need, and empower you to build your new home perfect down to the last detail. Plates that connect roof framing to ICF walls must be secured with 1/2-inch anchor bolts embedded a minimum of 7 in. Because of how durable ICF homes are, it does make remodeling difficult. If you foresee wanting to remodel your home in the future entirely, you might want to consider a more flexible building material. You can add more insulation to the outside, especially for a foundation, as Phil Dennis did in his Gaspereau Passive House with four extra insulation inches. Don’t count on natural convection (normal heat/cold airflow) to move air around the house.

Insulated concrete formwork, commonly known as ICF, is a construction method used in home building that utilizes styrofoam foundation forms to create a strong and well-insulated structure. This 4-bedroom, 3.5-bathroom ICF home plan features a spacious and practical layout. The open floor plan connects the kitchen, dining room, and great room, making entertaining family and friends a breeze. The master suite includes a large bedroom, walk-in closet, and private bath. 3 additional bedrooms provide ample space for family or guests, whereas the laundry room and three-car garage complete this functional home design. Apart from the master bath, the floor plan also includes 2 full baths.
The concrete provides exceptional strength and thermal mass; the foam provides a continuous layer of high performance insulation, and doubles as an ideal substrate for many finishes. Industry estimates suggest ICF homes may cost 0% to 10% more to build, depending on the manufacturer and other factors impacting local building costs. Importantly, the increased construction costs may be offset by lower utility bills.
Insulating concrete forms (ICFs) are panels or hollow blocks that are stacked, braced, and then filled with concrete. They are most commonly solid pieces of rigid foam, but some are composites of cement and other insulating materials. This floor plan features 2 bedrooms, 3 baths, 2 walk-in closets, a living room, a dining room, a utility room, a living room, a dining room, a covered porch, and a kitchen. The covered porch provides ample space for relaxing and dining, while the bedrooms are spacious and comfortable, with plenty of storage space. Unlike traditional wood-frame builds that use foam or fiberglass insulation, ICF construction utilizes interlocking forms with a lightweight foam exterior. These forms are available in many sizes and styles, enabling their use in every aspect of a home seamlessly and efficiently.
Dissatisfied with the ICF R-value of 25, she specified the installation of an additional 4 inches of extruded polystyrene on the exterior of the ICF walls to raise their R-value to 45. Another study compared an ICF building to traditional wood-frame construction and a wood-frame building built to higher than average standards. They also found that the operational energy use was responsible for 95% to 97% of the entire environmental impact for all three buildings. The researchers examined two hypothetical homes to address climate differences that can significantly change a building's energy performance. These homes would be built in five geographical locations in the United States and three locations in Canada.
Keeping the walls cooler when the outdoor temperature is hot keeps you and your family comfortable. Due to thermal mass, estimating the size of HVAC equipment for ICF homes is complicated. Simulated prior to construction, HVAC sizing is carefully calculated to produce the most cost and energy-savings.
On the first floor, you’ll find a spacious bedroom, a full kitchen, and a cozy living room. Upstairs, there are two more bedrooms and three bathrooms, giving you plenty of room to spread out. Plus, the family room on the second floor is the perfect place to relax or entertain guests. With its modern design and convenient layout, this house plan is sure to please everyone in the family. Concrete block houses have a number of benefits that make them an attractive option for many homeowners.
