Solid and Lasting Security
"The high-mass walls of an ICF home not only give it a remarkably solid feel,
but they also make it safer for the family. And make it a remarkably solid and

withstanding the ravages of hurricanes, tornadoes and fires, when all the
stick-built houses around them are in ruins.

"In fire wall tests, ICFs stood exposure to intense flame without structural
failure longer than did common frame walls... it will not support combustion.
Also, tests show that its tendency to transmit an outside flame source is less
than that of most wood products."
