Product description

CertainTeed Type X Gypsum Board is specifically engineered for fire-resistive applications, boasting exceptional fire resistance due to its special gypsum core that outperforms standard drywall in heat and flame resistance. Its increased thickness enhances fire protection. This versatile product finds common usage in commercial structures such as hotels, offices, and schools, and also extends its utility to residential settings like basements and garages. It facilitates the creation of fire-rated walls and ceilings that comply with or exceed relevant building codes. Among the notable advantages of CertainTeed Type X Gypsum Board are its high fire resistance, superior thickness, and durability. This makes it an ideal choice for fire-rated applications in both residential and commercial buildings. Installation follows the same methods as traditional drywall, ensuring ease of use. Furthermore, CertainTeed Type X Gypsum Board contributes to sound reduction through its thick gypsum core, enhancing acoustic comfort. It also improves thermal insulation, aiding in energy cost reduction and enhancing overall comfort levels. Its moisture resistance makes it an optimal choice for areas prone to flooding or condensation. CertainTeed Type X Drywall is a sustainable option made with 100% recycled paper and meets In addition to its superior performance, CertainTeed Type X also meets GREENGUARD® Gold for low emitting VOC content. This makes it an environmentally friendly choice for green building projects.

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 48% of the cradle-to-grave environmental impact potentials for CertainTeed Type X 5/8” Gypsum Boards at the Montreal, QC 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.
