Product description

M2Tech® Shaftliner for use in Shaftwall and Area Separation Firewall Systems is a 1" (25.4mm) thick drywall panel with a specially formulated fire resistive, noncombustible gypsum core, enclosed in a heavy moisture and mold resistant, blue gray colored, 100% recycled paper. M2Tech Shaftliner gypsum panel is designed and engineered for use in constructing lightweight Shaftwall and Area Separation Firewall assemblies. M2Tech Shaftliner gypsum panel is UL/cUL Classified and ULC Listed in fire resistance designs and features double beveled edges for ease of installation. In addition to its fire resistive properties M2Tech Shaftliner gypsum panel is also designed and engineered to provide added protection against mold when exposed to incidental or intermittent moisture during and after construction. When tested for mold resistance by an independent lab at the time of manufacturing, M2Tech Shaftliner achieved the best possible score of 10 per ASTM D3273.

Interpretation

Based on the results from the life cycle assessment model, the life cycle impacts are strongly driven by the manufacture. The impacts of the manufacture are primarily attributed to the natural gas usage needed for the ovens to dry the boards. The natural gas usage in the manufacture accounts for as much as 40% of the cradle-to-grave environmental impact potentials for CertainTeed M2Tech Shaftliner Gypsum Boards at the Nashville, AR facility.

The manufacturing of gypsum board (A3) has the highest contribution to Global Warming Potential impacts. The use of internally recycled gypsum material helps to reduce the overall environmental impact potentials by reducing the amount of external raw materials needed for the process.

Another potentially significant contributor to the overall environmental impact results is seen in the results for the installation of the Gypsum Boards. The installation waste accounts for the majority of the impacts for installation. The PCR requires the use of a 10% installation waste scenario in the absence of actual data. As there is currently no actual installation data available, and because installation techniques may vary widely among installers, CertainTeed has little to no influence on the installation impacts.

LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
