Product description
The Won-Door FireGuard™ is a versatile fire-rated accordion folding door designed to provide secure solutions for various architectural openings, including narrow corridors, short ceilings, and large spans up to 200 feet wide and 30 feet tall. It serves as a fire-protected opening in egress paths, is ADA compliant, and offers fire ratings ranging from 20 to 180 minutes. The doors feature smoke and draft seals, curved track options, and customizable designs to match adjacent finishes. They are engineered to meet regulatory standards such as IBC, NFPA, and UL, ensuring safety and reliability. Additional options include key switch controls, backlit exit hardware, infrared obstruction detectors, vision panels, and air pressure resistance levels. Made in the USA, these doors are ideal for applications requiring fire safety, security, and sound control.
Interpretation
The manufacturing of Won-Door products involves the direct procurement of raw materials and their subsequent processing at US-based facilities. The Product Stage (A1–A3) is the primary impact driver due to the energy required for raw material extraction and assembly. A limitation of this study is that upstream impacts are based on industry-average profiles rather than specific supplier data.
The 30-year Reference Service Life is contingent upon standard indoor use and adherence to the manufacturer's maintenance schedule. To modify the current environmental profile, evaluating a transition to renewable energy sources for manufacturing is suggested. Additionally, Won-Door should assess substituting raw material inputs with alternative options and prioritize collecting primary data from suppliers regarding their specific production techniques or energy mixes.
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.
