Product description

Spray-Applied Fire-Resistive Materials (SFRM) (UN CPC 54650) are composed primarily of binding agents such as cement or gypsum and may incorporate supplementary materials including quartz, bauxite, and other additives. These additional components are used to reduce density and enhance insulating properties by introducing entrained air. Chemical hardeners may also be included to accelerate curing or to improve the mechanical strength of the final product.

Passive fire protection materials (commonly referred to as fireproofing) are designed to prevent or delay the structural failure of steel and concrete elements when exposed to fire. These materials function by insulating structural members, thereby slowing heat transfer and preserving structural integrity for a defined period. A variety of fireproofing materials are available depending on the application requirements. Applied fireproofing systems are typically available in both wet-mix and dry-mix formulations and are most commonly spray-applied, although trowel application is also used in certain cases.

SFRM products are generally supplied as dry powder in bags and mixed with water at the point of application. Modern formulations are asbestos-free and do not contain intentionally added free crystalline silica, aligning with current health and safety standards. This Environmental Product Declaration (EPD) specifically covers standard-density SFRM products.

This report serves as the basis for a company-specific EPD representing a range of SFRM products manufactured at three GCP Applied Technologies facilities in North America, produced in accordance with varying product specifications.

Interpretation

The cradle-to-gate production (A1–A3) of Medium density Spray Applied Fire-Resistive Materials (SFRM) requires approximately 4.8 GJ of total primary energy (LHV) and results in about 423 kg CO₂e per metric ton of product (GWP, excluding biogenic carbon, IPCC AR6).

Across the life cycle stages, Module A1 (raw material extraction and upstream processing) is the dominant contributor, accounting for roughly 92% of total GWP. This confirms that the environmental profile of SFRM is primarily driven by raw material production.

Module A2 (transportation) contributes approximately 8–9% (~32 kg CO₂e), driven by the transport of raw materials to the manufacturing facility. Transportation also plays a notable role in impact categories such as photochemical ozone creation potential (POCP).

Module A3 (manufacturing) contributes a relatively small share at ~9.2 kg CO₂e (~2–3%), associated with on-site energy use and operational processes.

The environmental profile of standard-density SFRM-Medium Density is overwhelmingly influenced by raw material production, with transportation as a secondary contributor, while manufacturing impacts remain relatively limited. This suggests that the greatest opportunities for impact reduction lie in raw material optimization and upstream supply chain improvements.
