Congrats, Daiden: first EPDs open the door
Daiden just stepped into the transparency arena. In January 2026, they released two product‑specific Environmental Product Declarations for steel doors under EPD Hub, giving specifiers verified numbers instead of guesswork. That moves everyday openings from datasheet talk to submittal‑ready data and keeps bids from stalling where product‑specific EPDs are preferred.
What just launched
Daiden published two first‑ever EPDs in January 2026 that cover core steel door models used on commercial projects: Single‑Sided Steel Door and Double‑Sided Steel Door. The program operator on record is EPD Hub. Both declarations read as straightforward, product‑specific documents that align to EN 15804, which helps reviewers compare apples to apples inside building LCA tools.
Where Daiden plays (and why it matters)
These doors serve entrances, utility access, and fire‑rated applications in offices, education, retail, and light industrial. Doors are a small line on a schedule, yet missing EPDs can trigger conservative defaults in whole‑building models that make products less competitive. With verified declarations live, Daiden’s openings stay in the running when projects request product‑specific EPDs.
Operator context buyers ask about
The EPDs were issued through EPD Hub, recognized as an Established ECO EPD Programme Operator in December 2025, which means eligible EN 15804 EPDs appear in the ECO Portal (EPD Hub press release, 2025) (ECO Platform, 2025). That governance detail helps acceptance across EU‑aligned specs and gives procurement teams confidence in cross‑market use. As of July 1, 2025, ECO Platform lists EPD Hub with 3,301 ECO‑listed EPDs, a useful signal of program scale (ECO Platform, 2025).
At Daiden or competing against them?
Follow us for a product-by-product analysis to see how Daiden's new steel door EPDs stack up against Steelcraft, Curries, and Ceco Door.
Competitive snapshot
Steel doors are a crowded aisle. Steelcraft, an Allegion brand, lists current EPD coverage for several hollow‑metal door families under UL with validity extending into 2029, which shows established transparency in this category. Curries appears with related entries but without clearly current product‑specific EPDs in public registries. Ceco Door shows no current EPDs at the time of writing. Net effect, Daiden just caught the train, matching Steelcraft on verified documentation while gaining an edge where coverage is thin among brands like Ceco and Curries.
Scope notes worth flagging
Daiden’s two documents focus on single‑sided and double‑sided steel constructions. That maps cleanly to common specs for utility access, meter boxes, and standard entrance doors. If a project needs tested assemblies or frame pairings, pairing these EPDs with hardware and frame documentation will keep reviewers from hunting for proxies.
What this unlocks in specs and bids
Product‑specific, third‑party‑verified EPDs reduce back‑and‑forth in submittals and keep price from being the only lever. Teams can now model Daiden’s declared impacts directly instead of defaulting to conservative averages that add a hidden penalty. For distributors and GCs, faster approvals mean fewer late swaps and smoother closeout.
Website visibility check
We looked for a public sustainability or downloads page on Daiden’s website and could not locate these EPDs. Publishing the PDFs and a short explainer on product pages makes discovery easier for architects and procurement, which improves submittal speed and visiblity. A simple “Environmental Declarations” link in the main nav usually does the trick.
Keep the momentum
Two smart next steps stand out. First, extend coverage to adjacent door variants that show up often in schedules, for example insulated cores or standard fire‑rated options, so estimators are not forced to guess. Second, add a one‑page “How to specify” explainer that bundles the EPDs with test reports and frame pairings. Small moves, big payoffs when deadlines get tight.
Bottom line
Daiden’s debut is timely and market‑relevant. Two steel‑door EPDs in January 2026 put verified numbers behind everyday openings, which raises confidence with design teams and keeps options open on projects that now expect product‑specific declarations. Nice work, and now is the moment to scale coverage while the story has momentum.
Frequently Asked Questions
How many EPDs did Daiden publish and when were they issued?
Two product‑specific EPDs for Single‑Sided Steel Door and Double‑Sided Steel Door, issued in January 2026.
Which program operator verified Daiden’s EPDs?
EPD Hub, which is recognized as an Established ECO EPD Programme Operator and lists eligible EN 15804 EPDs in the ECO Portal (EPD Hub press release, 2025) (ECO Platform, 2025).
Did Daiden name an external LCA consultant in the public record?
We did not see a developer organization named in the public entries reviewed. If one is added later, that note can be updated on product pages.
Who are the nearest competitors for these door types and do they have EPDs?
Steelcraft shows current steel‑door EPDs under UL with validity into 2029. Curries and Ceco Door show limited or no current product‑specific EPDs visible at publish time.
