Safer Fiberglass Duct Board

Fiberglass duct board is avoided by most builders of low-toxic buildings for two reasons: 1) concern that glass fibers will be released from the exposed rigid fiberglass into the forced air stream; and 2) concern that mold and other microbial agents might grow in the fiberglass media and introduce contaminants into the forced air stream. Two of the leading manufacturers of fiberglass duct board now offer a product that reduces this risk.

Schuller International introduced SuperDuct™ in January 1993, and CertainTeed Corporation introduced ToughGard™ this past January at the NAHB Builder’s Show in Houston.
