Safe rooms are created by building any room with ICF walls, pouring a "concrete lid" on top, and installing a steel door. Recent hurricanes and tornado attacks have proven that only cinder blocks or insulated concrete forms have enough strength to withstand such raw power. Insulated concrete forms (ICFs), like Fox Blocks, offer a third and better wall system, capable of maintaining its integrity during heavy winds of over 200 mph.
