What makes A-One Forms better than the competition?

The A-One Form is the only in-house manufacturer of ICF forms in the industry. This allows us to maintain strict quality control standards as well as on time delivery. Our brackets are the toughest on the market, made of regrind polypropylene, which eliminates the thermal bridging and corrosion concerns. Our brackets are molded 1/2" below the surface of the block eliminating any shadowing concerns when finishing with stucco or EIFS products on the exterior of the building. In addition, our brackets run the full height of our blocks which eliminates the guess work when attaching dry wall or siding. The width of the bracket is a full 2 1/2" which is unique in the industry. Again, making it much easier to attach both external and internal wall products.

How high can you pour at one time?

We recommend that you pour one story at a time. The pour rate should not exceed four feet per hourThe A-One Form has been used in many multi-story residental and commercial structures, including a 4 and 5 story project in Minnesota. 

What is the R-value of A-One Forms forms?

The A-One Form has an R-Value of R-28 to R-32 using Thermographic Testing.

What kind of wall coverings can I use with A-One Forms?

The A-One Form comes with a full 2 1/2" bracket located every 8" on center making it easy to attach any type of wall covering including stucco, siding, or brick ties. The interior walls will easily accept sheet rock screws for attaching standard sheetrock.

How much rebar will I need?

This is determined by the design of the building and your local building codes. Our Online Estimator can also help you determine how much rebar is required.

What is LEED?

LEED stands for Leadership in Energy and Environmental Design. It is a green building rating system developed by the U.S. Green Building Council (USGBC). The purpose of LEED is to promote buildings that are environmentally responsible, profitable and healthy places to live and work. The LEED system was developed for designing, constructing and certifying the greenest and best buildings possible.

Is the A-One Form considered a green building material?

The A-One Form is extremely energy efficient. Since energy efficiency is a major component of green building, the A-One Form certainly fits into this criteria.

Are ICF’s resistant to mold and rot?

Yes. With traditional stick building moisture can become trapped within the open cavity of a wood stud wall, causing mold, mildew and rot problems. Since ICF’s are closed cavity construction, there is no place for moisture to accumulate. In addition, foam, rebar and concrete are resistant to mold and mildew.

Can an ICF home be remodeled?

Yes. Most contractors have the ability to create openings in ICF walls and concrete cutting tools are available at most rental centers.

Is the A-One Form code approved?

Yes. Every major code body in North America, including ICC and CCMC, has approved ICF’s. 

How quiet are A-One Form walls?

A-One Form walls have a sound transmission classification of STC 48, which is twice as high as a wood-framed wall. Structures built with ICF’s provide a super quiet interior.

Are termites a problem for ICF’s?

Just like wood frame construction, local building codes do require methods for protecting foam below-grade in high termite areas. However, ICF’s do not provide any food value for insects or rodents and termites cannot affect the structural integrity of an ICF wall because it is filled with concrete.

Are vapor barriers needed with ICF construction?

No. ICF’s provide a natural barrier against air and moisture because of the concrete and two layers of foam.

Do ICF structures provide extra safety?

Yes. ICF structures are up to 8 1/2 times stronger than wood framed structures. The standard design can withstand winds greater than 160 m.p.h. and they do not support combustion.

How are doors and windows installed?

A wooden or vinyl buck is built and incorporated into the wall prior to pouring concrete. When the concrete cures, doors and windows can be installed.

Do ICF walls need to be waterproofed?

Yes. As with any below-grade construction, waterproofing is required. There are several products to choose from and we have provided links to some of the most popular products on our accessories page.

Do the forms stay put after the concrete is poured?

Yes. ICF forms are used to allow builders a solid concrete wall. Also, the A-One Form brackets (webs) run the full height of the form so much less bracing is needed during pouring. The majority of ICF’s on the market require major bracing because their forms cannot support the weight of the concrete.
