What Sindal Trappen just published
Sindal Trappen released two product‑specific EPDs in April 2026 covering half‑turn wooden staircases with and without risers, each offered with or without a railing on one side. The declarations are verified under EPD Norway using the NPCR 015 Part B for Wood and wood‑based products for construction. In plain words, buyers now have third‑party numbers for a core stair family, not a generic proxy.
Program operator and rulebook, translated
The program operator is EPD Norway, a long‑standing European operator that follows EN 15804. The PCR behind these EPDs is NPCR 015 Part B, which spells out what counts, what to measure, and how to report for wood products so results are comparable rather than apples to spaceships. That rulebook clarity helps teams move faster in LEED v5‑oriented bids where product‑specific EPDs are increasingly expected.
Scope notes that matter in bids
These are product‑specific EPDs for a defined staircase geometry and options. That precision helps design teams model embodied carbon without the guesswork multipliers that often come with category averages. Less guesswork means fewer last‑minute swaps for “the one with an EPD” and more predictable bid outcomes for everyone.

Quick company backdrop
Sindal Trappen manufactures custom and series‑produced staircases for residential and small commercial projects. Think modern home renovations, townhome infill, and boutique mixed‑use where design, function, and schedule all have sharp elbows. Publishing now aligns the portfolio with how specifiers work today, not yesterday.
Competitive snapshot
In Nordic and Northern European stair and access systems, a few names set the pace. Weland AB carries a multi‑product EPD that includes galvanized steel stairs under EPD International AB, which signals mature coverage across ramps, railings, and trappor. Dolle A/S has an EPD for its CLICKFIX loft ladder under Danish Technological Institute, so access solutions from that brand are already on the board. Brødrene Midthaug AS shows expired EPDs and no current listings right now, which means project teams still need product‑specific data when shortlisting there. Net effect. Sindal Trappen just moved from “may be considered” to “easy to consider” on projects that screen by EPD first.
Why this helps on day one of LEED v5 conversations
Project teams increasingly treat a product‑specific EPD like a passport to enter the room. It reduces the carbon accounting penalty that hits products without verified data and saves coordination time across design, contractor, and supplier. That is especially true on residential blocks and light mixed‑use where staircase packages get locked early while structural and MEP dance continues.
What we don’t see yet
We did not see a dedicated EPD download page on sindaltrappen.dk at the time of writing. If it is not there yet, visibility is key. Add the PDFs to product pages and a central sustainability hub so estimators and architects can grab them in one click. If these declarations need to land in the global directories specifiers use quickly, reach out and we can share how to get listed within a day or two for future EPDs.
From first to full coverage
First EPDs are the on‑ramp, not the finish line. Many manufacturers expand to adjacent stair geometries, alternate materials, and common options next. The easiest way to keep momentum is to tighten data collection at the plant and avoid one‑off spreadsheets. Teams that treat LCAs as a repeatable workflow, not a heroic sprint, typically publish faster with fewer do‑overs. It’s definately worth it.
The takeaway
Two staircase EPDs in April 2026 put Sindal Trappen squarely in the consideration set for transparency‑driven projects. Against competitors with broad or partial coverage, this debut closes a credibility gap and opens doors where verified numbers are mandatory. Keep publishing across top sellers, keep the files easy to find, and the spec math starts working in your favor.
