Congrats, Tammer on your first EPDs

What just launched

Tammer has published eight first‑ever Environmental Product Declarations in May 2025 for single‑ and double‑leaf metal doors. The set covers galvanized and stainless sheet‑metal door families, including fire‑rated models at EI30, EI60, and EI120. These read as product‑family declarations rather than single SKUs, which is exactly what design teams want when specs flex by size and finish.

Who they are and why this matters now

Tammer is an Estonian manufacturer of sheet‑metal and steel‑profile doors used in residential and public buildings, with a strong footprint across the Nordics and Baltics. Doors are often a small line on the schedule, yet they can derail submittals if environmental data is missing. With current EPDs in the library, Tammer removes that friction and keeps attention on performance, delivery, and total cost instead of paperwork.

Program operator and LCA partner

The EPDs were verified and published with EPD Hub. Modeling and documentation credit on the records goes to LCA Support as the developer organization. The rule sets cited include EN 17213 for windows and pedestrian doorsets as well as the operator’s Core PCR v1.1. Validity runs into 2030, which keeps submittals clean for the next cycle.

The spec math, simplified

Product‑specific, third‑party verified EPDs remove the conservative “penalty” teams apply when they lack declared data. For projects chasing LEED, Option 1 typically seeks at least 20 distinct products with compliant EPDs, and a product‑specific Type III counts as 1.5 entries toward that tally (USGBC, 2025). That weighting can tip close bids when everything else looks even.

Competitive heat check

Here is how the field looks for comparable door categories in Europe.

• ASSA ABLOY Mercor Doors has current, product‑specific EPDs covering steel doors and fire gates under the Polish program operator ITB. Coverage is active across multiple fire classes, which keeps them visible in public tenders.
• JELD‑WEN publishes a broad suite of door EPDs, including interior door families and steel frames, with several entries issued in 2025 and valid into 2030. That makes them a known quantity in submittals.
• Daloc AB shows past activity but no current EPDs visible at the time of writing. For Nordic projects that insist on product‑specific EPDs, that gap hands Tammer a near‑term edge in like‑for‑like steel fire doors.

Takeaway, Tammer has entered the transparency arena in a category where leaders already use EPDs to streamline approvals. They instantly catch up to the front pack and gain ground where a rival has yet to refresh declarations.

Scope notes buyers will care about

• Family coverage matters. Tammer’s documents bundle single‑ and double‑leaf variants with finish and hardware scope typical for doorsets. That reduces the risk of late‑stage rework when an architect swaps a brushed stainless finish for powder‑coat.
• Fire ratings are explicit. EI30, EI60, and EI120 listings map neatly to common project asks and help avoid interpretive debates during review.

Where to find the documents

Tammer has public posts confirming publication and pointing readers to the operator library. See their news update, “Tammer’s First EPDs for Single‑ and Double‑Leaf Metal Doors are Completed,” which links to the live records on EPD Hub and references a documentation section on their site. If the PDFs are not yet centralized on a single documentation page, doing so will make submittals faster and reduce email ping‑pong. Visibility is key for spec teams.

What smart next steps look like

• Extend coverage to steel‑profile doors and any glass‑lite variants that ride the same schedule. That keeps one product line from triggering generic fallbacks in a whole‑building LCA.
• Mirror the operator PDFs on a clearly labeled Documentation page. Many buyers bookmark once and return often.
• Align renewals with sales pushes. Teams that plan six months ahead of expiry avoid last‑minute updates that can stall a bid.

The bottom line

Tammer’s May 2025 EPD wave turns reputation into verifiable data. It levels the field against established names and, in specific door classes, may even create an advantage where others are still catching up. Small move on paper, big move in the room where specs are decided. It is definately the right signal at the right time.
