Product description

CertainTeed Type X Infinaé™ CarbonLow™ 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 Infinaé™ CarbonLow™ 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.

Interpretation

Based on the results of the life cycle assessment model, the environmental impacts are primarily driven by the manufacturing stage and its associated upstream and downstream activities. The largest contributors to the overall cradle-to-grave impacts are installation, raw material transportation, and raw material production. Installation is a particularly significant contributor to the overall environmental impact results for gypsum board products.

The PCR requires the application of a 10% installation waste scenario when actual installation data are unavailable. Since no site-specific installation data currently exist and installation practices can vary considerably among contractors, CertainTeed has limited influence over installation-related impacts. The use of internally recycled gypsum material helps reduce overall environmental impact potentials by decreasing the need for virgin raw materials and reducing associated upstream environmental burdens.

Although the manufacturing stage (A3) contributes a relatively small portion of the product's cradle-to-grave Global Warming Potential (GWP), it represents the primary opportunity for impact reduction because it is directly controlled by the manufacturer. The reduction in environmental impacts is primarily driven by the transition from fossil fuel-based manufacturing to electrified production powered by renewable electricity. By replacing natural gas with renewable hydroelectricity in Québec, the project significantly reduces direct (Scope 1) emissions associated with energy-intensive manufacturing processes. In addition, the implementation of multiple heat recovery systems, enhanced energy-efficient plant design, and improved process control strategies further reduces overall energy demand and improves operational efficiency. Together, these measures are expected to improve manufacturing energy efficiency resulting in substantial reductions in environmental impacts while maintaining product quality and production performance.

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.
