Now a brand under the Horton Pedestrian Access Solutions division of Overhead DoorCorporation following its acquisition in 2021, the company is best known for pioneering the Won-Door FireGuard, the world’s first accordion-type horizontalsliding fire door to achieve a three-hour UL rating. These specialized systems are highly valued by architects for providing immense design flexibility; theyremain retracted in wall pockets until activated by a fire or security alarm, allowing for wide-open floor plans and curved configurations that still meet strictInternational Building Code (IBC) and NFPA safety requirements while ensuring accessibility for individuals with disabilities.Further information can be found at:https://wondoor.com/Limitations, Liability and OwnershipEnvironmental declarations from different programs (ISO 14025) may not be comparable. Comparison of the environmental performance of products usingEPD information shall be based on the product’s use and impacts at the building level, and therefore EPDs may not be used for comparability purposes whennot considering the whole building life cycle. EPD comparability is only possible when all stages of a life cycle have been considered. However, variations anddeviations are possible. Example of variations: Different LCA software and background LCI datasets may lead to differences results for upstream ordownstream of the life cycle stages declared.

Data QualityPrecision & CompletenessPrecision: Inventory data were directly measured, calculated, or conservatively estimated from primary sources using consistent units and QA checks.Background processes from ecoinvent v3 were adopted with their documented uncertainty/precision metadata where available, preserving atransparent record of data quality.Completeness: The product system's mass balance and inventory completeness were thoroughly checked. Some exclusions were made in line with thePCR requirements, such as personnel impacts, R&D activities, business travel, and point-of-sale infrastructure. However, no data were intentionallyomitted.Consistency and ReproducibilityConsistency: Primary data for all modules were consistently gathered aiming at the highest level of detail possible. Background processes weremodeled mainly with the ecoinvent database. The same allocation rules, cut-off criteria, and impact assessment methods were applied throughout,ensuring methodological coherence and consistent data quality across the entire LCA model.Reproducibility: This study ensures reproducibility by providing comprehensive disclosure of input–output data, dataset choices, and modelingapproaches. A knowledgeable third party should be able to approximate the results using the same data and modeling methods.RepresentativenessTemporal: Primary data were collected for a 12-month period representing the 2024 calendar year to ensure the representativeness of post-consumercontent. Secondary data from the ecoinvent v3 database are typically representative of recent years.Geographical: Primary data represent Won-Door's production facility. Where applicable, differences in electric grid mix were considered usingappropriate secondary data. The use of country-specific data ensures high geographical representativeness, and proxy data were only used whencountry-specific data were unavailable.Technological: Both primary and secondary data were tailored to the specific technologies studied, ensuring high technological representativeness.Life Cycle Module DescriptionModules A1–A3: The LCA model covers the production of raw materials and components for commercial steel doors and steel frames (A1), which are thentransported to the manufacturing facility by truck or other relevant modes of transport (A2). The manufacturing stage (A3) begins with receipt of thesematerials, which are cut, formed, welded, finished, and assembled into finished steel doors and frames. When applicable, additional components such asinsulation cores, glazing kits, louvers, vision panels, reinforcements, and hardware preparations are incorporated during fabrication and assembly.Modules A4–A5: Once manufacturing is completed, the finished steel doors and steel frames are transported to the construction site or distribution point andthen to the end user (A4). For installation (A5), material losses associated with installation may be considered where relevant. This module includestreatment of installation waste and disposal of packaging materials generated during delivery and installation.Modules C1–C4 and D: At end of life (C1–C4), the steel doors and steel frames are assumed to be removed from the building, collected, and sent toappropriate waste management processes. Individual material streams, including steel and other ancillary materials, are handled separately for recycling,energy recovery, or disposal as applicable. Loads and benefits beyond the system boundary are considered in Module D, including the potential benefitsassociated with recovery and recycling of steel and the displacement of primary materials.LCA DiscussionAllocation ProcedureAllocation of co-products was avoided, to the extent possible, based on the guidance given in ISO 14044:2006, 4.3. Energy use at the facility level wasallocated by the amount of product produced. The manufacturing process does not consume water or generate wastewater or air emissions, other thanthose from fuel combustion. Solid waste was estimated using packaging masses and material losses and allocated following the polluter pays principle.Standard Won-Door FireGuard™ DoorWon-DoorPage 7 / 13

Scaling FactorsDoor areaWeight1 m213.6 kg3ft x 7ft26.6 kg600 ft2760.kgProduct weights in the table were derived from door area using a constant mass-per-area assumption based on the reference configuration. This approachis applicable only to geometrically similar door variants with the same material composition, thickness, and manufacturing process.InterpretationThe manufacturing of Won-Door products involves the direct procurement of raw materials and their subsequent processing at US-based facilities. TheProduct 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 thatupstream 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 thecurrent environmental profile, evaluating a transition to renewable energy sources for manufacturing is suggested. Additionally, Won-Door should assesssubstituting raw material inputs with alternative options and prioritize collecting primary data from suppliers regarding their specific production techniquesor energy mixes.0%20%40%60%80%100%Standard Won-Door FireGuard™ DoorWon-DoorPage 11 / 13

These are classified as hazardous due to their lead and sulfuric acid content; however,these materials are contained within sealed units and pose no health risk under normal operating conditions. Detailed safety, handling, and toxicologicalinformation is provided in the Product Safety Data Sheet (SDS), available upon request.At the end of the product's life, these batteries must be removed and managed through specialized hazardous waste streams. This requirement is reflectedin the Hazardous Waste Disposed (HWD) indicator reported in Module C4.No other substances included in the REACH Candidate List of Substances of Very High Concern (SVHC) are present in the product above a concentration of0.1% by weight.Further InformationReference Service LifeNameValueUnitRDL30YearsDeclared product properties (at the gate) andfinishes, etc.24-gauge V-grooved steel panels; factory-applied thermal set polyester.Material Specs / GaugeDesign application parametersCompliance with UL 864 and UL 263 and IBC§1010.3.3 for fire-rated openings.Regulatory StandardsAn assumed quality of workInstalled in accordance with manufacturerinstructions, NFPA72 and NFPA 80 by factory-trained technicians.Installation StandardOutdoor environmentNot applicable (Indoor use only).Exposure TypeStandard Won-Door FireGuard™ DoorWon-DoorPage 12 / 13
