Congrats, Lindab Hungary: first EPDs for circular ducts

What just went live

Lindab Hungary’s debut EPD covers SR and SRSS circular duct families. Scope reads product‑family rather than one-off SKUs, which matters for day‑to‑day quoting across diameters and variants. The declaration was issued in March 2025 and is current as of today.

Why this matters in specs

Ductwork shows up early and everywhere in MEP design. Having a product‑specific, third‑party verified EPD lets project teams model real impacts instead of conservative defaults that can penalize a bid. It also makes it easier for distributors and GCs to keep the original submittal intact instead of hunting for alternates late in design.

Lindab Hungary, in brief

Lindab manufactures circular ducts and fittings for commercial and residential ventilation, serving installers, OEMs, and project teams across Central and Eastern Europe. The new EPD lines up with how the product is actually bought and installed on jobsites, which is the point.

Competitive snapshot

Here is how the field looks for the same basket of ventilation decisions:

• Swegon has a broad EPD footprint for AHUs and room products. We did not find duct‑specific EPDs in their set, which means Lindab’s circular‑duct EPD helps close a common gap. See our overview of their coverage for context (Swegon on EPD Guide).
• Systemair also publishes EPDs, especially for AHUs and fans, yet we could not locate a current, metal duct family EPD as of February 10, 2026 in the major listings we checked.
• DuctSox takes a different route with fabric ducting and does list EPDs. For projects fixed on metal ducts, Lindab’s new declaration is the like‑for‑like document decision‑makers expect.

Translation for bids, Lindab Hungary just entered the transparency arena where it counts most for their catalog. In many tenders thats the nudge that keeps the specified brand in place.

Smart material notes engineers will ask about

Lindab flags circular ducts available with high recycled content options that align well with low‑carbon specs, including a GR2 option advertised at up to 75% recycled steel (Lindab SR product page, 2026). If a project is chasing portfolio‑level emissions targets, that pairing with a product‑specific EPD is straightforward to defend.

Where to find it on their site

• Global product catalog entries for SR circular ducts list EPD documentation and related downloads. Start here if you need a quick link for submittals: SR Circular duct page on Lindab’s catalog (global).
• On Lindab Hungary’s sustainability hub we found an EPD explainer but not a direct product‑level download link as of February 10, 2026. Visibility matters. We recommend adding a simple “EPDs and Downloads” panel on the Hungarian site so project teams can grab the PDF without extra clicks.

Timing tip most teams miss

There is often a lag of weeks to months between a program operator issuing an EPD and that document appearing in the databases specifiers use daily. Shortening that lag keeps live bids moving. If learning how to get new declarations listed within a day or two would help, reach out and we can share the playbook.

The takeaway

Lindab Hungary’s first EPD covers the heart of its ventilation offer with a family‑level declaration. That narrows the documentation gap versus established HVAC brands and gives specifiers a clean, defensible choice on circular metal ducts. Keep the momentum by surfacing the download prominently on the local site and lining up the next wave of fittings to round out coverage.
