How an ICF House is Built

Learn about the different components of an ICF house.


“Building with ICFs decreases your utility bills 40%-60% each month and makes your home quiet, comfortable and disaster resistant.”

Choose BuildBLock ICFs,  the ultimate in energy-efficiency and safety for your family.


Build an ICF Safe Room & Foundation

ICF Safe Rooms are like any other room in your home: master bathroom, bedroom, closet, pantry, media room and more.

A temperature controlled room that isn’t musty or damp inside your home for your family’s safety. No worries about moving cars and climbing down into a hole in your garage, ICF safe rooms can be above ground or in your basement. ICF safe rooms also prevent you from being trapped under debris in your garage waiting for rescue.


Build an ICF Basement and Foundation

Build your crawlspace or basement with ICFs and create a safe place for you and your family. ICF basements let you maximize the square footage of your home regardless of your lot size.

Highly energy-efficient ICF basements typically are drier with lower humidity than standard basements. ICF basements are insulated, waterproof, quiet, and an excellent value.

ICF basements create additional insulated living space and provide more comfort for the entire home.


Build all the outside walls of your home using ICFs for maximum benefit.

Build all outside walls of your home using ICFs. The insulation below ground in your foundation or basement are even greater above ground.
Any cost difference is recouped within the first 3-5 years of owning your home. The actual out of pocket cost difference is offset by energy savings alone compared to wood frame construction.
Benefits such as safety from disaster, noise reduction, improved indoor air quality, and peace of mind begin immediately and never stop.”



Insulating Concrete Forms (ICFs)?

You should think of Insulated concrete forms (ICFs) as giant building blocks for adults. They are hollow foam blocks that are stacked into the shape of the exterior walls of a building, reinforced with steel rebar, and then filled with concrete. The foam holds the concrete in and stays in place providing the highest level of insulation. Insulated concrete forms combine one of the finest insulating materials, Expanded Polystyrene (EPS), with one of the strongest structural building materials, steel-reinforced concrete. The result is a wall system of unmatched comfort, energy efficiency, strength, and noise reduction.

Insulating Concrete Forms are easy, affordable, and unbeatable.

The model below shows you how the outside walls of your home look when you build with ICFs. The blocks are stacked to the height of your walls, reinforced with steel rebar, filled with concrete, and then brick, stucco, rock, or siding is attached to the outside. On the inside, your plumbing and electrical are run through the foam itself after the walls are poured. Drywall, plaster, or stucco is attached to the inside, then finished with trim, flooring, and other finishes. In the end, your home looks like any other but performs 1,000% better.

ICF Home Advantages

Insulated Concrete form structures are much more comfortable, quiet, and energy-efficient than those built with traditional construction methods. Use the menu on the right for more details about the advantages of insulated concrete form homes and buildings.

Congratulations on deciding to build your new home. As you begin formulating the plans for your new home, there seems to be no end to the number of choices you have to make. It’s natural to pour hours of time and effort into choosing the right paint, wall coverings, exterior finish, and other aesthetics for your new home. But first, take some time to decide what will be inside those walls.

Traditional wood-frame construction can’t compare to the safety, permanence, and energy efficiency of walls built with insulating concrete forms.

A common question home buyers ask is,
“If ICFs are so great, why isn’t everyone using them?”

Benefits of an ICF Home:

  • 30-70% savings in energy consumption and costs (good for your pocketbook and the environment)
  • Tornado, hurricane, and earthquake resistant (keeping your family and belongings safe and sound)
  • 75% reduction in outside air infiltration (less dust and allergens)
  • Five times quieter than a wood-frame home
  • Building with ICFs saves at least 10 trees per home
  • ICFs can be used to build virtually any home plan, using any finish – brick, stucco, siding, and more
