DensGlass Silver® wall sheathing can be used in place of Oriented Strand Board (OSB), foam sheathing, cement board, 1/8" foil-faced sheathing, or 1/2" fiberboard sheathing in residential wall construction when applied in compliance to model building codes. 1/2" DensGlass Silver is a structural wall sheathing when using fastener and fastener spacing as listed in IRC Section R 602.10.3, method 5. It is backed by a 90-day in-place exposure warranty unmatched by paper-faced sheathing.
When tested, as manufactured, in accordance with ASTM D 3273, DensGlass Silver® paperless gypsum sheathing panels score a 10, the highest level of performance for mold resistance under the ASTM D 3273 test method.
The score of 10, in the ASTM D 3273 test, indicates no mold growth in a 4-week controlled laboratory test. 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, DensGlass Silver sheathing provides increased mold resistance compared to standard paper-faced wallboard products. |
