What are problems with ICF construction?

ICF construction foundations usually cost more to complete versus the standard wood form and pour. ICF forms require extra support during setup to ensure the forms remain in place before and after pumping the concrete into the ICF forms.

Can you screw into ICF walls?

Drywall is fastened to an Advantage ICF wall the same way as it would be in a wood frame house except that I recommend you use drywall screws rather than nails. When you screw it on make sure you hit one of the plastic webs or ties spaced at 8” on center for 6” ICF walls or 6” on center for 8” ICF walls.

Do termites eat ICF blocks?

One advantage of building with ICF is that the structure of the ICF foundation or wall will not be affected by termites, unlike wood-framed homes. Neither the EPS foam nor the polypropylene webs are a food source for termites.

How long will ICF home last?

ICF longevity The foam in ICF walls does not degrade, and reinforced concrete is used for some of the strongest buildings around. So you can expect an ICF construction to last well over 100 years. We've already seen how they perform well in storm-hit areas (high winds and flooding) and even in earthquake zones.

Can you nail into ICF walls?

Any type of siding can be applied to ICF by screwing or nailing it directly to the embedded webs. Textured acrylic finish systems (TAFS) are one of the most common, and also most cost-effective to apply.

Are ICF walls fireproof?

ICF Walls Have a 4-Hour Fire Rating ICF walls have been tested up to 2000° Fahrenheit for up to four hours in fire conditions. Wood-framed walls usually collapsed within 60 minutes, but the ICF wall did not experience any structural damage. Wood does burn, however, concrete does not.

How strong are ICF walls?

Homes made with ICF are sometimes called “1,000-year homes” because there's little to prevent them from surviving intact for hundreds of years. The walls are strong enough to withstand up to 250 mph hurricane winds and tornadoes, earthquakes, and are fire-resistant for up to 4 hours.

Can an ICF house withstand a tornado?

Homes built with insulated concrete forms (ICF), like Fox Blocks, maintain their integrity during the high winds of a tornado. Insulating concrete forms can withstand winds of over 200 mph.

What is the fire rating of an ICF wall?

As a reference point, Logix ICF homes have a four-hour fire rating. In fact, ICF walls have been tested up to 2000 degrees Fahrenheit (typical in a common house fire) while wood walls typically collapse within an hour. Essentially, walls made out of concrete prevent fire from spreading to the inside of the home.

Why is freight important in molding?

Freight is a significant factor in pricing, which is why the chart notes the location of molding facilities. Panel systems (knockdown forms) reduce shipping, but require more labor as jobsite assembly. Reversible interlocks and specialty forms can make installation go faster and reduce waste. Even more important than cost is the installer’s experience and familiarity with the forming system.

How much does a 48x16 block weigh?

They’re considerably denser—and heavier—than regular ICFs; a 48”x16” block weighs nearly 50 lbs. and larger ones need to be craned into place. This typically means higher shipping costs in locations outside the southwestern U.S.

What is vinyl form?

Vinyl Forms: These are best suited for projects where the form will double as a final finish, such as fish farms, car washes, and wastewater tanks . Vinyl is a poor insulator, but EPS inserts can be added to one side of the cavity if needed.

What is a screen grid block?

All are screen-grid blocks, meaning the concrete forms a series of columns and beams (usually every 16 inches on center).

How wide is a 6 inch concrete wall?

Actual core widths vary widely; a six-inch nominal wall may vary from 5.5 to 6.75 inches, which accounts for the variability in the “Sq. Ft. per Cubic Yard of Concrete” column. The thickness of the foam sidewalls, which affects form strength, insulation value, and amount of raw material used, also varies.

When does ICF compare?

Every year, ICF Builder publishes an ICF comparison chart in the January/February issue. As in past years, this will also include comparisons of EPS decking systems and non-traditional stay-in-place forming systems.

Is ICF decking popular?

How thick is a reinforced concrete wall?

Several instances were cited where structural engineers had designed reinforced concrete walls well in excess of four inches thick for ordinary home construction. Yet the same engineers might allow a four inch wood frame wall.

What is the purpose of a concrete roof?

Properly tied together with a concrete roof, the structure no longer consists of walls only but becomes a structural shell or box with expon entially greater strength because of the rigid diaphragm action of the roof elements providing support to the tops of the walls in both the x and y directions.

What happened in 1995?

In the major Kobe, Japan earthquake of 1995, the world saw photos of extensive damage to buildings and transportation structures and learned about the deaths attributable to the event. Thirty-nine mid-rise box-frame precast reinforced concrete apartment buildings were located within the zone of influence of the 6.8 Kobe trembler. There was no structural damage to a single apartment building from the quake and they were all green-tagged for immediate occupancy the day after the shake – confirming the viability of the box-frame structural solution.

How fast can a tornado wind go?

As a possible worst-case scenario, we have calculated the lateral loads which might be applied to a house by a tornado wind velocity of 350 mph (5 63 kph). Although the U.S. National Weather Service has estimated that tornado winds may reach a velocity of 500 mph (800 kph), the highest tornado wind speeds ever documented, 318 mph (516 kph), were measured using Doppler radar during a tornado in Oklahoma in 1999.

What is the Saffir-Simpson scale?

The Saffir-Simpson scale is a standard scale for rating the severity of hurricanes as a measure of the damage they cause and it is based upon observations of numerous North Atlantic Basin hurricanes.

What was the worst thing that happened in Guam in 1993?

Even though damage to some structures from the 1993 Guam Earthquake was severe, little human injury and no fatalities occurred. Hardest hit were the island’s hotels, which had the same design weaknesses typical to many high-rise hotels damaged in earthquakes worldwide.”

Is there a trend for concrete roofs?

There is not yet a sufficient number of concrete roofs to set a trend, but the authors believe that as ICF technology for concrete roofs matures that such roofs will become competitive with wood truss roofs when life costs are compared.

What is the minimum length of a jog in an ICF?

ICF construction eliminates cuts and reduces waste. Jogs in the wall should be a minimum of 18”. Also, adding the length of two corners together (long side + short side) in addition to 4-foot block lengths is the most efficient increment for working with ICFs and eliminates most cuts.

How thick is a plumbing vent?

Plumbing locations and venting need to be considered. Typically 2.5” of foam thickness is available to run water pipes, electrical wire or conduit, and plumbing vents. Water closet vents require a pipe with a larger diameter than the ICF foam thickness. Install vents in an interior wall partition or in the concrete core itself.

What is an ICF wall?

ICF walls are thicker than wood or metal stud framed walls. If redesigning a plan for ICFs, the wall thickness will affect the interior and/or exterior dimensions. The preferred strategy is to place the inside edge of the ICF block on the inside edge of the framed wall so the growth in the thickness of the wall is moved to ...

How thick is a header?

Header thicknesses are typically 12-inches or larger, and often 16 or 24-inches. Working in increments of 8-inches will reduce waste and using 16-inches matches the full BuildBlock ICF block height, keeping the process simple.

How many inches between concrete openings?

We recommend that spacing between openings be 12-inches or greater. This ensures proper flow and consolidation of concrete and the creation of a structural column.

How high should a wall be?

Wall heights should be based on 8″ or 16″ increments and adjusted based on floor system thickness.

What is the minimum offset for a facade?

If the feature is architecturally, stylistically, or aesthetically desired, a minimum of an 18” offset is recommended. Additionally, you can build features as a facade, using brick, block, or lumber.

What is the IRC code for concrete?

For one and two family dwellings, the International Residential Code (IRC) addresses foundations and below grade walls in Section R404 and above grade walls in R611 for homes up to two stories plus a basement. For larger buildings like multi-family and commercial structures, an engineer is typically required for structural design and an Evaluation Service Report documenting approval of the ICF for the type of construction mandated for the project will often be needed to finalize approval.

Why are ICFs used in construction?

Over time, some ICF manufacturers consolidated, leading to a smaller number of larger companies. Because insulating concrete forms systems offered performance benefits like strength and energy efficiency and were initially more expensive to construct, the first target market was high end home construction. Custom home clients were willing and able to pay extra for the premium quality. As word of ICFs grew and innovations reduced manufacturing and installation costs, builders began using the forms for mid-price-range homes. Some production builders now create entire large developments using insulating concrete forms.

What is the difference between a post and beam and a flat?

The wall produced by "grid" systems has a waffle pattern where the concrete is thicker at some points than others. "Post and beam" systems have just that – discrete horizontal and vertical columns of concrete that are completely encapsulated in foam insulation. Whatever their differences, all major ICF systems are engineer-designed, code-accepted, and field-proven.

What can be recycled to make concrete?

Concrete can be made using supplementary cementing materials like fly ash or slag to replace a portion of the cement. Aggregate can be recycled (crushed concrete) to reduce the need for virgin aggregate. Most steel for reinforcement is recycled. Some polystyrenes are recycled.

What is the R value of concrete insulation?

Some estimates place the savings at 20 percent or more. The R-value for a typical Insulating concrete form is about 20. The walls can often have high air tightness 10 to 30 percent better than frame-with compatible windows, doors, and roof.

Why were concrete forms more expensive than frame construction?

Although there were some obstacles—costs could be greater than frame construction because people didn’t understand the system, builders had to work closely to get code approval, and materials were proprietary— the number of insulating concrete forms producers grew. As a result, competition increased and costs moderated.

What was the purpose of the ICFA?

By the mid-1990s, the Insulating Concrete Form Association (ICFA) was founded to do research and promotion of the products, working toward building code acceptance. They also worked with the Portland Cement Association to build awareness of this type of construction. Although there were some obstacles—costs could be greater than frame construction because people didn’t understand the system, builders had to work closely to get code approval, and materials were proprietary—the number of insulating concrete forms producers grew. As a result, competition increased and costs moderated.

What is ICF Construction?

Building with ICF walls involves dry-stacking ICF blocks, like building with Lego bricks. An ICF block is two rigid insulation panels ( often 2.5" or more thick of expanded polystyrene) held together with plastic cross-ties. The ICF blocks are available in various concrete core widths and the cross-ties support the installation of rebar horizontally and vertically. Once the interlocking ICF blocks form the wall, concrete is placed and cures, resulting in a permanent exterior framework, ready for finishes, plumbing and electrical.

How much more is ICF than wood frame?

While ICF construction may cost 3 to 5 percent more than wood-frame construction up front, the long-term financial advantages of building high-performance ICF walls can more than make up for the higher construction costs. ICF construction provides life-time savings with lower utility bills and HVAC operating costs, reduced labor costs, higher rents, improved occupancy, and added long-term value to a building project over similar wood-frame projects.

How do fox blocks help with earthquakes?

Steel reinforcing bars att ach the Fox Blocks ICF shear walls to the foundation. When an earthquake occurs, the design of Fox Blocks effectively resists severe sideways (lateral) in-plane forces that push the top of the wall one way while the bottom stays either stationary or is forced the other way (racking the wall).

What is an ICF building?

In addition, ICF is easy to cut and shape and can include customized designs, such as large openings, cathedral ceilings, curved walls, long ceiling spans, and custom angles. Once complete, an ICF building can look just like a wood-framed structure.

What finishes are compatible with ICF?

ICF walls are compatible to any exterior finish - stucco, siding, masonry, simulated stone, etc. All finishes can be directly installed to the ICF following manufacturers specifications.

Can ICF walls be used during a hurricane?

This statement is partially correct. A more accurate statement is that ICF construction can outperform traditional wood-frame construction during a severe hurricane event or seismic activity. Importantly, a report by the Portland Cement Association found that ICF walls have more structural amplitude and stiffness to weather the in-plane shear forces, during severe winds or an earthquake than wood- and steel-framed walls.

Is Fox Blocks ICF fast?

The opposite is true. ICF construction is typically fast and easy, which saves contractors time and money. For instance, Fox Blocks ICF is an all-in-one wall assembly that combines five building steps into one, including air barrier, vapor retarder, structure, insulation, and attachment. Combining five steps into one, with one contractor accelerates project delivery by eliminating the need to coordinate multiple trades while achieving all of the wall assembly’s goals. A faster weather tight building with ICFs, means faster project completion and occupancy.

What is the minimum thickness of a concrete wall?

Below grade walls must have a minimum 6" (150 mm) concrete core. In some regions, an 8" (200 mm) concrete core is the minimum allowed thickness for below grade walls. The 4" (100 mm) form cannot be used below grade as a foundation wall.

How tall is a 6" wall?

The 6" (150 mm) form, above grade, is limited to approximately 14' (4.2 m) in height. Walls higher than 14' (4.2 m) must use an 8" (200 mm) or larger form.
