Resists Rot, Mold and Mildew
Wood framed walls are typically susceptible to wood rot, mold, fungus, and bacterial growth.
- High air infiltration allows moisture to collect in the hollow cavities. In fact, a typical electrical outlet absorbs 30 quarts of water per heating season in a wood frame wall1
- Secondly, wood studs and OSB sheathing are all food sources for mold.
Unlike wood frame walls, CELBLOX Insulating Concrete Forms (ICF) do not support wood rot, mold, fungus, or bacterial growth2
1. ICF resists water infiltration:
- Low air infiltration
- EPS is non-hydroscopic and is commonly used in Minnow Buckets
- No hollow cavities to collect water
2. EPS, concrete, and rebar are not a food source for mold, fungus, or bacterial growth.
It is important to remember that buildings breathe similar to living organisms, and just like in living organisms, the air movement needs to be managed. Unmanaged air infiltration though wood framed and steel stud framed walls:
- Is not filtered or dehumidified
- Can bring in moisture which results in condensation, encouraging mold growth
- Carries dirt and pollutants
- Can penetrate deep into the building space through ceiling spaces, wall cavities and other unintended plenums
CELBLOX ICFs virtually eliminates unmanaged air infiltration, mitigating these issues.
Restricts Pest Infiltration
Because CELBLOX ICFs are a concrete, monolithic structure, there is no stud wall cavity that will allow for infestations to harbor colonies of pests and insects.
CELBLOX 6” ICF walls have a Sound Transmission Coefficient (STC) of 51, up to 8X quieter than conventional wood framed or steel stud framed structures3. This makes CELBLOX the ideal application for movie theaters, schools, hotels, hospitals, and urban infill developments.
