ARE ICFS SAFER THAN WOOD?
Yes, ICF walls are significantly safer that wood-frame walls.
ICF walls can be engineered to be wind-rated to over 300 mph. A traditionally built 2×4 or 2×6 framed offers little resistance to debris impact and hurricane wind loads – traditionally built framed walls require considerable improvements to match the strength and resistance of ICFs.
An ICF wall with a 6.25” concrete core has a 4 hour fire rating. A traditionally built 2×4 or 2×6 wood frame wall has a 45 minute fire rating..
Plus, ICF walls are inorganic in nature and do not support mold growth or rot, wood-frame walls will.
