Product description

Stonres is a seamless, resilient floor that combines distinctive design elements with performance and function, using intricate patterns in a smooth, stain-resistant, ergonomic and noise-reducing system. Stonres RTZ is frequently specified for Operating Rooms due to its durability, stain-resistance and easy-to-clean properties. It also meets the challenges of many commercial markets, such as education, stadiums and retail spaces

Interpretation

Raw materials are sourced from suppliers, transported to manufacturing facilities, and mixed to produce products. The product stage (A1-A3) has the highest environmental impact, especially due to raw material production and energy use, impact amplified in the use phase (B4) from recoatings. The Market scenario shows higher use-phase impacts due to a shorter estimatedservice life (ESL). End-of-life impacts are relatively low, as products are assumed to be landfilled with building demolition waste. Switching to renewable energy is advised for products with high manufacturing energy demands. The manufacturer should explore lower-impact raw materials and work with suppliers using sustainable methods or renewable energy to enhance product sustainability.

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.
