What just launched
Dutch Environment Corporation BV released a product‑specific EPD for Sonodec 25, covering an insulated flexible duct with a perforated inner liner, mineral wool blanket, and laminated outer jacket. The declaration is published with the program operator EPD Hub, aligning with EN 15804 and ISO 14025. Scope reads like a focused product entry rather than a broad catalog umbrella, which keeps comparisons clean in whole‑building models.
Who they are, and why this matters now
Under the DEC International brand, Dutch Environment Corporation makes flexible ducts, ready‑made connectors, and sound‑attenuating links used between air handlers, main duct runs, and terminal devices. These are small in size but big in impact on comfort and commissioning. With the EPD, everyday HVAC links move from datasheet talk to third‑party verified impacts that fit modern submittals and carbon accounting.
Category fit
Sonodec 25 lives in the ventilation components universe many teams tag under Division 23. It shows up wherever designers need bendable connections that add acoustic control and help manage condensation. An EPD here helps estimators drop conservative defaults and model the real product instead of a generic.

Competitive picture
Two European names already publish EPDs for similar flexible duct and sleeve solutions: Westaflex and REC Indovent. Their public records span insulated flex ducts, connectors, and compact silencers, which means spec teams can already compare like for like. On the broader ventilation side, Lindab shows wide EPD coverage for circular ducts, fittings, attenuators, and plenum boxes. That breadth sets buyer expectations even if a flexible insulated flex‑duct EPD has been rarer to see. Dutch Environment Corporation now meets that bar in its core SKU and puts its name on shortlists where product‑specific declarations are non‑negotiable.
What changes in bids and submittals
When a team must model embodied carbon, products without a product‑specific EPD often carry a penalty in calculations. A verified declaration replaces that penalty with the manufacturer’s measured impacts, which keeps the conversation on performance, delivery, and price instead of assumptions. For HVAC packages that bundle lots of small parts, one missing EPD can drag the whole schedule back into manual edits. This launch removes that friction for a common connector.
Program operator choice
Publishing with EPD Hub gives buyers a familiar verification route and makes future renewals predictable. That matters for multi‑year frameworks where renewal timing and rule updates can otherwise create last‑minute scrambles.
Website visibility check
We looked for the new EPD on decinternational.com and did not find it on product or sustainability pages at the time of writing. Visibility is key. Adding a prominent EPD link on the Sonodec 25 page and a central “Environmental Declarations” hub will help distributors and MEP engineers grab the right file fast. It is definately a low‑effort, high‑return update.
The takeaway for manufacturers watching
Dutch Environment Corporation has moved first on the flexible insulated duct in its lineup and joined a peer set that already treats ventilation parts as EPD‑ready. For competitors without a product‑specific declaration in this niche, the risk is simple. Specs with strict documentation will gravitate toward the options that keep models clean and approvals quick. For anyone planning their first wave, pick the category your sales team touches most, make data collection painless across plants, and publish with an operator your buyers already recognize.
