Congrats Westaflex: first EPDs put flexible ducts on spec
Westaflex just entered the transparency arena. In April 2025 the company’s first product‑specific Environmental Product Declarations arrived for flexible aluminum ducts, then more followed in May. For sales and spec teams, that means fewer speed bumps on low‑carbon projects and a cleaner path through submittals where verified data beats generic assumptions every time.
What Westaflex just published
Westaflex now lists four product‑specific EPDs covering ventilation components in Division 23. The set includes Compact and Compact MM flexible aluminum ducts, an insulated flexible duct designed for sound attenuation, and a PE insulation sleeve for ducts. The first EPDs posted in April 2025, then two more landed in May 2025. All are issued by program operator EPD Hub under ventilation‑focused PCRs and appear to cover product families rather than single one‑off SKUs, which is the smarter play when variants share materials and processes.
Why this matters for their catalog
Westaflex builds air‑distribution essentials used across residential and light‑commercial ventilation. Think flexible connection pieces, bendable aluminum runs that fit tight spaces, and sleeves that keep condensation and heat loss in check. That is exactly the tier of hardware that gets value from product‑specific EPDs because these parts often appear repeatedly across a project’s plans.
Can we see the EPDs on their site today
Yes. Westaflex’s Swedish catalog flags EPDs on product pages, including Compact MM flexible duct and its Compact base hose, plus the insulated flexible duct Aku‑Comp and the duct insulation sleeve. See the product pages for details and EPD IDs: Compact, English, Aku‑Comp, English, and Insulation sleeve, SE. A single, centralized EPD hub on the main site would make life even easier for specifiers who prefer one bookmark.

The operator behind the PDF
The declarations are verified and published by EPD Hub, a program operator recognized across EN 15804 markets for construction EPDs. If your buyers ask where an EPD lives, pointing to a known operator answers that in seconds. Learn more about operator context here: EPD Hub overview.
Competitive snapshot in ventilation
Three peers define the benchmark today. Systemair shows a strong catalog of EPDs across fans and AHUs with current validity windows into 2029 under EPD Norway, which signals mature coverage in equipment but not necessarily in flexible ducting. Lindab has select EPDs for air distribution products, for example ceiling diffusers published with EPD Hub, and continues to expand its materials strategy on steel backed by public disclosures. See our quick take here: Lindab. Aldes lists multiple ventilation‑unit EPDs through the PEP program. In short, equipment is well covered among incumbents, while product‑specific EPDs for flexible ducts and sleeves are still rare. Westaflex’s move puts tangible, spec‑ready data where many alternates still rely on generics.
What this unlocks in bids
A verified EPD lets project teams model the actual product rather than a conservative default. In Norway’s framework, for example, using generic values triggers a 25 percent uplift, which can quietly penalize products that lack product‑specific EPDs in tender scoring (DiBK TEK17 §17‑1, 2024). The same dynamic shows up in many European specs and in owner requirements tied to whole‑building LCA. Westaflex’s new set helps keep their parts on lists without extra debate.
Timing note many teams overlook
These EPDs first appeared in April 2025, and it is now February 2026. There is often a delay of weeks to months between program‑operator issuance and visibility in global directories that architects and engineers search first. Reducing that lag matters. If your team wants playbooks to get future EPDs listed within a day or two, reach out and we can share options.
Our take, simply put
This is a smart, surgical debut. Starting with Compact, Compact MM, the insulated flexible duct, and the insulation sleeve gives Westaflex enviromental coverage where their SKUs repeat most in schedules. It also narrows a gap where several big names emphasize equipment EPDs over connection pieces. That is how you take more of the spec pie without trying to boil the ocean on day one. And yes, adding a simple EPD hub page on the corporate site would definately help buyers find the right PDF in seconds.
Frequently Asked Questions
Which product families are covered by Westaflex’s first EPDs and who issued them?
Four declarations cover Compact and Compact MM flexible aluminum ducts, an insulated flexible duct for sound attenuation, and a PE insulation sleeve. All are issued by EPD Hub under ventilation‑related PCRs.
When did Westaflex’s first EPDs go live?
The first wave published in April 2025, with additional entries appearing in May 2025.
Do close competitors already have similar EPD coverage for flexible ducts?
Major peers like Systemair and Aldes show robust EPD libraries for equipment such as AHUs and fans. We did not find broad, product‑specific EPDs for flexible ducts and sleeves among them, which gives Westaflex an early advantage in that subcategory.
Are the EPDs easy to find on Westaflex’s website?
Yes on product pages for Compact, Aku‑Comp, and the insulation sleeve. Creating a single EPD hub page would further improve discoverability for specifiers.
