Insulating Concrete Form Structures are Comfortable & Quiet

When planning a new house, consider the greater well-being that comes from living with more even temperatures, sharply reduced drafts, noticeably greater quiet, and healthier air. That’s what you get with an insulating concrete form home. When surveyed, over 80% of ICF homeowners mentioned the great comfort of their home, compared with just 22% of wood-frame homeowners.*

Healthier Air


Indoor air quality is often something that people don’t think about until it goes bad. Maintaining a healthy environment is essential in any indoor space and ICFs provide a wall system that greatly assists in this effort.

BuildBlock ICF walls provide a tight exterior building envelope. Walls that are “tight” (meaning they have low air infiltration) is the first step in controlling the indoor air environment. Due to the dense foam insulation that makes up ICFs, BuildBlock buildings have high R-values and low air infiltration rates. The solid concrete core provides superior thermal mass, meaning a lot of energy is required to change its temperature and eliminates the potential for outside air leakage. Compare that to a traditional wood framed home with loose cellulose or fiberglass insulation. Despite best practices and skilled labor, a wood home will almost always have voids in the wall especially around doors, windows, plumbing, and electrical outlets. 

Lasting Results

  • ICF walls reduce air infiltration by 75%.
  • Eliminate dust mites.
  • Prevent dangerous and costly mold.
  • The effects of hay fever, asthma, and other airborne allergies can be greatly alleviated as a direct result of the reduced leakage of outside air, which brings dust, pollen, and other pollutants.
  • Indoor air pollution is a great health concern today. ICF walls are non-toxic. The measurement of air contents of actual ICF houses shows an almost complete absence of any emissions.

Insulating concrete form homes provide unparalleled peace and quiet and true protection from outside noise. In sound transmission tests, ICF walls allow less than one-third as much sound to pass through than regular frame walls.
