Insulating Concrete Form Installers, Insulating Concrete Form Contractors, Insulating Concrete Form Design

Foundation Masters, LLC is the most experienced I.C.F Contractor in Florida!  Insulated Concrete Form (ICF) is a system of Pre-engineered foam blocks that stays in place as a permanent interior and exterior substrate for walls, floors, and roofs.  The forms are interlocking modular units that are dry-stacked and filled with concrete.  The units lock together somewhat like Lego blocks and create a form for the structural walls or floors of a building.  ICF construction has become commonplace for both low rise commercial and high performance residential construction as more stringent energy efficiency and natural disaster resistant building codes are adopted.

Energy efficiency

  • Minimal, if any, air leaks, which improves comfort and reduces heat loss compared to walls without a solid air barrier
  • High thermal resistance (R-value) typically above 3 K·m²/W (in American customary units: R-17); this results in saving energy compared with uninsulated masonry.
  • Continuous insulation without thermal bridges or “insulation gaps”, as is common in framed construction
  • Thermal mass, when used properly and combined with passive solar design, can play an important role in further reductions in energy use, especially in climates where it’s common to have outside temperatures swing above inside temperatures during the day and below at night.
  • With I.C.F. construction and proper attic insulation you will have a complete return on your investment in Five years.


  • Insulating concrete forms create a structural concrete wall, either monolithic or post and beam, that is up to ten times stronger than wood framed and block unit structures.
  • Structural integrity for better resistance to forces of nature, compared to framed and block walls, like wind loads up to 300mph.
  • The components of ICF systems — both the poured concrete and the material used to make the ICF — do not rot when they get wet.

Sound absorption

ICF walls have much lower rates of acoustic transmission.  Standard thickness of 6″ ICF walls have shown sound transmission coefficients (STC) between 46 and 72 compared to 36 for standard fiberglass insulation and drywall.  The level of sound attenuation achieved is a function of wall thickness, mass, component materials and air tightness.

Fire protection

ICF walls can have four- to six-hour fire resistance rating and negligible surface burning properties. It is worth pointing out that the International Building Code: 2603.5.2[ requires plastic foam insulation (e.g. Polystyrene foam, Polyurethane foam) to be separated from the building interior by a thermal barrier (e.g. drywall), regardless of the fire barrier provided by the central concrete. Forms.

Indoor air quality

Because they are generally constructed without a sheet plastic vapor barrier, ICF walls can regulate humidity levels, mitigate the potential for mold and facilitate a more comfortable interior while maintaining high thermal performance.

Environmental sensitivity

ICF walls can be made with a variety of recycled materials that can minimize the environmental impact of the building. The large volume of concrete used in ICF walls has been criticized, as concrete production is a large contributor to greenhouse gas emissions.
