Better Physical Performance
Tested in accordance with ASTM C 1177, and applicable CAN/CSA-A82.27, ASTM C 931
and C 79 requirements, GlasRoc® Sheathing meets or exceeds all physical property requirements. Results showed improved physical performance compared to glass-faced gypsum sheathing products including:
| • |
Reduced humidified deflections |
| • |
Superior flexural strengths |
| • |
Excellent nail-pull resistance |
Enhanced Dimensional Stability
GlasRoc® Sheathing will withstand normal exposure to UV, rain, wind, ice, and
snow.
It is dimensionally stable under changes in temperature and relative humidity. To back it up, CertainTeed provides a 12 month limited exposure warranty.
Excellent Fire Protection
Testing in accordance with ASTM E 136 proved that GlasRoc® Sheathing, with its acrylic coating, is noncombustible and offers superior fire performance compared to paper-faced sheathings. It has a zero flame spread and zero smoke developed index when tested per CAN/ULC-S102 and ASTM E 84 for surface burning characteristics.
Easy to Handle and Install
GlasRoc® Sheathing is handled and installed like regular paper-faced sheathing. In addition, it:
| • |
Can be scored and cut with a standard utility knife. No special tools required. |
| • |
Snaps free after scoring only one face. |
| • |
Attaches to framing with the same fasteners used for paper-faced gypsum. No special fasteners required. |
| • |
Is easier to handle because skin irritations are minimized due to the fully-embedded glass mats and our innovative acrylic coating. |
| • |
Has uniform field and edge hardness, making trimming & fastening quick and easy. |

Long Term Protection to Weather Exposure
GlasRoc® Sheathing, with its homogenous water resistance throughout the board, offers
superior freeze/thaw resistance. It will withstand exposure to UV, rain, wind,
ice and snow. To back it up, CertainTeed provides a 12 month limited exposure warranty.
GlasRoc® Sheathing provides enhanced surface liquid water resistance while allowing the building’s vapour drive to be unimpeded.
Mould and Mildew Resistance
Because GlasRoc® Sheathing contains no starches, sugars, paper facing or pulp, it will resist mould and mildew growth. When tested in accordance with ASTM D 3273, GlasRoc® Sheathing exhibited no evidence of mould or fungal growth after a period of 28 days of exposure, yielding a rating of 10.
Increased Durability
GlasRoc® Sheathing resists delamination because the glass mats are fully-embedded into
the panel, creating a more durable, dimensionally stable panel.
Standards and Code Compliance
GlasRoc® Sheathing conforms to ASTM C 1177 standard, applicable CAN/CSA-A82.27, CCMC, ASTM C 931, and C 79 requirements. Installation standards, where applicable, are Gypsum Association Publication GA-253, GA-216 and ASTM C 1280 for gypsum sheathing and soffits.
