Myths of Insulating Concrete Form Construction Technology

The Insulating Concrete Formwork (ICF)  Construction Technology manufacturing thrives with imprecise material. Some have been pass down by members of the industry, while others represent simple misconceptions about technology. Most of this misinformation is do by people who simply lack the correct knowledge behind the information. The hardest part of examining ICFs is not finding the information, but rather sorting out all the technology hub

Almost every aspect of the Insulating concrete Construction Technology industry is affect by misinformation, but the most common topics involve discussions of R-value, waterproofing, and termites and insects. To blow this myth up and get a clearer understanding of this myth, you need to have a solid understanding of the R-value and the difference between PERFORMANCE and TRUE R-values.

Myth About insulting concrete in construction

Myth 1: R value

An R value is the measure of resistance (R) to heat flow. Heat flow can be fight by insulating resources such as malleable foam or inorganic threads or it can be reserve by thick solid materials such as dense stonework or concrete. The higher the R value, the higher the resistance and the better the insulation value.

All building materials transfer heat to some degree. Heat transfer can be measure using one of the following: 1. Conductivity (k); Conductivity (c); 3. Transmission (U); 4. Resistance (R).

When it comes to stating R-values ​​in residential concrete construction technology, insulation concrete values ​​on a wall or ceiling generally refer to the R-value of the installed insulation material, not the wall or ceiling. For example, when a 2×4 stud wall is insulate with R-11 block insulation, the developer says the wall is R-11. This is not completely accurate and IS NOT TRUE, as approx. 20% of the wall is not insulate at all. The wooden frame and cladding have an R value, but for insulation reasons they contribute very little. The actual R-value or R-value for PERFORMANCE ends between R-3 and R-9. Add to this, the fact that the wall is full of penetrations, such as electrical plugs, etc., and the fact that the wall itself is basically hollow in nature. This additional thought leads to another discussion about air leakage through the wall.

Insulting concrete walls In Construction Technology

The claim that Insulating concrete Construction Technology walls are an R-50 start a few years ago after the Insulating Concrete Formation Association (ICFA) and several members commission CTL labs in Chicago to perform some R-value testing and analysis. The report summary basically said that depending on the climate zone. The PERFORMANCE R values ​​for Insulating concrete Construction Technology are as high as an R-52 compare to typical timber frame and slat construction. For the comparison to be correct, one must ensure that the comparison.

It is made in relation to the alternative to Insulating concrete Construction Technology in the project in question. On average, the performance R-value is much less than the declared R-50. Consumer research should be done to clarify the current project comparison. In short, Insulating concrete Construction Technology performs PERFORM to an R-50, but this statement is not accurate when it comes to insulation value.

It is worth noting that there are many research opportunities on the Internet. I do not own or control any of the proposed research links listed in this article.

Myth 2: waterproofing

Yes, concrete construction of this class must always be waterproof and this includes Insulating concrete Construction Technology.. In some jurisdictions in the United States, a combination of dimple membranes and peel and stick membranes or spray / spray products must be use to comply with local building codes. It is best to check with your local building registration staff and your local Insulating concrete Construction Technology supplier to ensure that you meet the minimum code requirements and use only EPS compliant products.

Myth 3: termites and insects

Conferring to the Insulating concrete Construction Technology Association, the Global Covering Code has supplies. In the IRC to permit foam to be secondhand under class. In addition to chemical soil treatment, the IRC determines that low-quality foam. It can be use on the exterior of the wall if one of the following requirements is met:

  1. All interior partitions and roof rails are construct of a non-combustible material, such as steel bolts or pressure-treat wood.
  2. An approve method will be use for the protection of the foam and the structure
