What are Insulating Concrete Forms (ICFs)?

Insulated concrete forms (ICFs) are hollow foam blocks which are stacked into the shape of the exterior walls of a building, reinforced with steel rebar, and then filled with concrete. 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.

ICF is perfect for that secure storage or basement under your new Yurt!

Insulating Concrete Forms… Easy. Affordable. 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 it attached to the outside. On the inside your plumbing and electrical are run through the foam itself after the walls is 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.


What’s the difference between insulating concrete forms and insulated concrete forms?

Insulated and insulating concrete forms are the same. We generally use insulating because the insulation is continuous and ongoing throughout the life of the home.


Why Choose Insulating Concrete Forms (ICFs)? What are the advantages of an Insulating Concrete Form (ICF) home or building?

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.

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



Ballistic ICF Safe Rooms

Protect valuable assets with an ICF Safe Room.

BuildBlock ICF Safe Room

An ICF Safe Room provides protection from winds as high as 250 mph and can be engineered to stop almost any small arms projectile. These safe rooms are created by building any room (such as the master bedroom closet) with ICF walls, pouring a concrete “lid” on top, and installing a steel door. Not only does it keep your family safe, a closet Safe Room is a fire-resistant storage area for your valuables and heirlooms. Integrating a safe room in to your new home design, adding to an existing home, or retrofitting current home are all affordable and straightforward.

Looking for a home plans with a safe room or a safe home?

BuildBlock has partnered with Nelson Design Group, a national home designer. Their entire catalog of 2,500 home plans are available to you. Find one you like and BuildBlock will discount the cost of ICF conversion when you purchase your block. Visit Nelson Design Group and see their home designs – Every year, tornadoes, hurricanes, and other extreme windstorms injure and kill people, and cause millions of dollars worth of property damage in the United States. Even so, more and more people build homes in tornado- and hurricane-prone areas, possibly putting themselves into the path of such storms. Having a safe room built for your home or small business can help provide “near-absolute protection” for you and your family or employees from injury or death caused by the dangerous forces of extreme winds. – FEMA 320


Safe Room Options

Safe Room can be used as another room in your home. Make your safe room a closet, bathroom, bedroom, office, or pantry. The safe room can even encompass the entire basement if needed.

ICF Safe Rooms are like any other room in your home. Master bathroom, bedroom, closet, pantry, media room and more. Building a safe room doesn’t mean building an ugly bunker. Using ICFs, you can finish this room however you would like and use it as a part of your home each day. Depending on the size and scope of your individual project, you can almost break even in costs and enjoy your Safe Room each and every day as a new addition to your home and a safe haven in inclement weather.

Fire Resistance of Concrete Homes

Of all construction materials, concrete is one of the most resistant to heat and fire. That fire resistance gives houses built with insulating concrete forms certain safety advantages. And those advantages give builders and buyers yet another reason to consider using ICFs for their next project.

ICF Fire Ratings

How well do ICF walls hold up in a fire?

Unlike wood, concrete does not burn. Unlike steel, it does not soften and bend. Concrete does not burn until it is exposed to thousands of degrees Fahrenheit — far more than is present in the typical house fire.

This has been confirmed in so-called “fire-wall” tests. In these tests, ICF walls were subjected to continuous gas flames and temperatures of up to 2000°F for as long as four hours. None of the ICF walls ever failed structurally. All of the ICFs tested were of the “flat” or “uninterrupted grid” type, having no significant breaks in the concrete layer [like BuildBlock ICFs]. In contrast, wood frame walls typically collapse in an hour or less.

ICF Flame Spread

Do they stop fire from spreading?

Concrete walls have also proven more resistant to allowing fire to pass from one side of the wall to the other. This is especially of interest in areas with brush fires that could spread indoors.

The fire wall test confirms this rule for ICFs once again. Part of the test measured how well the wall slows the passage of heat and fire from the side with the flame to the other side. The ICF walls tested did not allow flames to pass directly through. They also did not allow enough heat through to start a fire on the cool side for 2-4 hours. In contrast, wood frame walls typically allow both flame and fire-starting heat through in an hour of less.
