<br /> 'ASTM D3273 Mold Resistance Testing:In independent tab tests conducted on USG Securock°Brand Gypsum-Fiber Roof Board
<br /> and USG Securock°Brand Ultralight Glass-Mat Roof Board at the time of manufacture per ASTM D3273 Standard Test Method
<br /> for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber,both panels scored a 10.The
<br /> ASTM lab test may not accurately represent the mold performance of building materials in actual use.Given unsuitable project
<br /> conditions during storage,installation or after completion,any building material can be overwhelmed by mold.To manage the
<br /> growth of mold,the best and most cost-effective strategy is to protect building products from water exposure during storage and
<br /> installation and after completion of the building.This can be accomplished by using good design and construction practices.
