Is an ICF home tornado proof?
A. An ICF wall, when properly built, will with stand 250 MPH winds. It will take a projectile hit of a 2 x 4 at 100 MPH ( this is what it estimated the debris inside a tornado will be flying around at). There are many photo documentation’s showing an ICF home, or commercial building still standing after a tornado has wiped out every thing around it. Most of the time, the limitation to an ICF home in a storm is the roof and windows. If a person wants to maximize there protection, then an ICF safe room should be designed into the home or building. Amvic offers an entire foam formed system for the walls and roof, making an entire room that is safe. To say anything is tornado proof is a large step, but a proper built ICF safe room will offer you the most protection available. I have never heard of one failing when tested by man made created environments, or mother nature’s wrath.
