Whole Building ICF

Whole Building Construction

ICF’s are not just for foundations. Many of our projects use ICF’s for all the exterior wall construction, both above ground and below. Reinforced concrete is one of the strongest building products available and coupled with the EPS foam insulation, it is also one of the most energy efficient. ICF Construction is in line with the cost of traditional construction and ICFs are used to build small and large homes, schools, churches, and other commercial buildings.

Advantages of ICF Construction 

High Performance Building Envelope

With the thermal mass of the concrete and the high insulating properties of the EPS foam, your ICF home can reduce heating and cooling costs by over 50% compared to conventional construction.

ICFs work to provide energy efficiency in the three categories of thermal transfer:

  • Conduction (R-Value). With 5” of EPS, this gives walls a high R-Value of 22.
  • Convection (air infiltration). With a monolithic concrete wall, air infiltration is dramatically reduced from a stick frame/fiberglass insulated wall.
  • Radiation (thermal mass) – The thermal mass of the concrete in the wall will help maintain a consistent temperature of the structure and help to alleviate temperature fluctuations, improving structure energy efficiency.

All the above categories work together to achieve an “effective R” of around a 45 in our Maine climate for the whole structure. What this means, is that a traditional stick built home would have to be insulated to an R-45 to achieve the same energy efficiency as an ICF structure. This makes ICF costs comparable to traditional building methods with better results. 

Safer Longer Lasting Structure

ICF structures will stand the test of time. The EPS foam will not breakdown over time which provides the structure with consistent insulation protection for the life of the structure. ICF structures can withstand fire for up to 4 hours, winds up to 200+ MPH and seismic activity. Insect, such as ants, are not attracted to the foam as a food source. There is no food value in the foam and with the foam properly covered there are not any access points for insects or ants.

Eco – Friendly and Healthy Living 

  • ICF contain 50%+ by weight of recycled content. 
  • Reversible forms lead to reduced construction waste and it’s 100% recyclable. 
  • ICF structures are sustainable and require less energy so the life cycle cost of the structure is less than traditional construction. 
  • No CFCs, HCFCs are used during production and no formaldehyde is generated. There is no off gassing from forms. 
  • Mold, Mildew and dust particles are blocked, creating a cleaner indoor air.

Quiet, Peaceful Home

  • ICF construction cuts sound transmission by 75% over standard construction practices leaving the structure quiet and comfortable. 

Design Flexibility

  • ICF construction allows for almost any home design. Curved walls and corners as well as various wall heights are achievable with ICF construction. 
  • With furring strips every 6″, there is plenty of attachment points for any type of interior or exterior coverings. 

Cost Effective 

  • For about the cost of granite counter tops, you can have an ICF home that will save you money month after month, year after year with reductions in utility bills and reduced maintenance.
