Concern with allegations regarding wood fiberboard
The North American Fiberboard Association (NAFA) would like to point out it has provided new information that renders unnecessary the warning given in NRCA Associate Executive Director of Technical Services Mark Graham's March column, "A concern with fiberboard insulation," page 12.
Specifically, I informed Graham that in my capacity as NAFA executive director I have visited the plants and questioned production personnel and members of NAFA's board of directors for each company and learned that at each location, cane fiber is not and has not ever been used as a raw material.
The few allegations of corrosion that have been made only involved cane fiberboard. NAFA's members have not received any such allegations against wood fiberboard. This has been true for decades of wood fiberboard production and use.
