Dr. Hahn’s first EPDs land hinges in specs
Door hardware gets swapped fast when paperwork lags. With its first Environmental Product Declaration published in October 2025, Dr. Hahn moves hinges from a quiet component to a verified line item buyers can check and trust. That change matters on projects tracking embodied carbon and following LEED v5 material rules, where product‑specific, third‑party verified data is increasingly a ticket to entry.
What just launched
Dr. Hahn GmbH & Co. KG has published its first product‑specific EPD covering lift‑off hinges for metal doors. The declaration reads as a product family rather than a single SKU, which makes it useful across common configurations. Scope includes cradle‑to‑gate with options for A1–A3, plus A4, A5, B2–B7, C and D, so specifiers can reference impacts beyond manufacturing when needed.
Why it matters in the hardware aisle
Hinges sit in every door schedule, yet they often lacked project‑ready environmental data. An EPD defuses that friction. Teams no longer lean on pessimistic defaults that can nudge a swap to a brand with verified numbers. When hinges carry their own third‑party verified table, bids move faster and substitutions slow down.
Who issued and verified it
The EPD was published with ift Rosenheim GmbH, a German institute and EPD program operator focused on windows, doors and facades. Their program follows ISO 14025 and EN 15804 with external verification, and is widely recognized across European procurement. Learn more about their role here: ift Rosenheim GmbH.

A quick look at Dr. Hahn’s core business
Dr. Hahn designs and manufactures hinges for metal and PVC profile doors used in commercial and residential buildings. Think screw‑on hinges, butt hinges, clamp hinges and concealed hinges that keep heavy entrance doors aligned and serviceable over years. That footprint puts the brand in frequent contact with architects, fabricators and hardware distributors where paperwork can tip the spec.
Competitive snapshot
What we see in public EPD catalogs today. Door‑hardware majors like ASSA ABLOY and dormakaba already publish multiple product‑specific EPDs across locks, closers and access systems under European operators such as IBU and the International EPD System. Hinge specialists are a different story. We did not find current hinge‑focused EPDs for SIMONSWERK or HOPPE in the sources we checked at the time of writing. Translation. Dr. Hahn has entered the transparency arena in a category where big generalists publish broadly, while pure‑play hinge rivals show thinner public coverage.
How to put the new EPD to work
- Attach the PDF to door schedules and submittals so the hinge line item clears review without back‑and‑forth.
- Align the hinge EPD with locks and closers that already carry EPDs on the same project, so the opening is fully covered.
- If a plant‑specific or concealed‑hinge family carries the volume, plan the next declaration now while momentum is high.
Visibility check on Dr. Hahn’s site
We looked for a dedicated EPD or sustainability page hosting this new document and did not see a live listing at the time of writing. If it is not up yet, add it to downloads and the sustainability section so fabricators dont have to hunt. Visibility is free performance.
The takeaway for specability
A first EPD for hinges is more than a box tick. It turns a small component into a data‑backed choice that keeps projects moving and protects margin. In a market where majors already publish across door hardware and some niche rivals have yet to show hinge‑specific EPDs, Dr. Hahn’s October 2025 debut signals serious, practical transparency. That is how enviromental data earns a seat in the schedule.
