Mold Concerns Prompt Product Alert for Georgia-Pacific Exterior Sheathing

In a letter sent Aug. 18 to the Knoxville Association of General Contractors, Georgia-Pacific Corporation announced a product alert for DensGlass Gold. The popular gypsum exterior sheathing is used on many commercial construction projects.

The product was manufactured in Georgia-Pacific's Savannah, GA, plant between April and June 14.

The alert was sent out because the four-foot by eight-foot boards of gypsum sheathing could be susceptible to mold growth along the edge glue lines when exposed to extreme moisture and high temperature weather conditions, Georgia-Pacific said.

The boards — similar in size to wallboard and used as an under-layer for building exteriors such as brick, stucco and stone — were shipped to Tennessee, North Carolina, South Carolina, Florida, Georgia, Alabama and Virginia.

A sales manager for the company said that the problem has been corrected by using a different glue to process the sheathing.

Georgia-Pacific doesn’t know how many projects may be affected, but it is advising contractors with concerns to contact its Atlanta-based headquarters.

Owners of completed buildings containing the defective boards will receive letters of indemnity and warranty from the manufacturer to protect them against possible damage if the boards can't be replaced.

Questions about Dens materials can be answered bya G-P gypsum representative at 866-245-1076.
