_{*The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting. No material can be considered mold proof. When properly used with good design, handling and construction practices, DenGlass® Shaftliner provides increased mold resistance compared to paper-faced panels.}
