Why this debut matters
AZEK builds outdoor living systems for homeowners, multifamily, and light commercial projects, from TimberTech decking and railing to AZEK and Versatex trim and exterior cladding. When a product family carries a third‑party verified EPD, design teams can document embodied‑carbon choices without detours, which keeps preferred SKUs in play instead of getting swapped late in buyout.
What AZEK published in June
The company’s first EPD covers TimberTech Advanced Polyvinyl Chloride (PVC) Decking. Publication month is June 2025. Scope reads as product‑specific for Advanced PVC decking boards under MasterFormat Division 06. The declaration is listed with the program operator Smart EPD.
Who issued it, and the rulebook behind it
The EPD is published by Smart EPD. If you want a plain‑English primer on that operator, see Smart EPD in our program‑operator series here: Smart EPD, Untangled. Smart EPD states conformance with ISO 14025 and EN 15804 conventions, which are the core standards specifiers expect (Business Wire, 2023) (Business Wire, 2023). The EPD document does not name a separate LCA consultant, so developer attribution is not publicly listed.
Work for AZEK or competing against them?

The competitive picture
Composite and PVC decking is a tight race on design and durability. Transparency now shapes shortlists too.
- Fiberon shows multiple product‑specific EPDs for decking and for Wildwood composite cladding verified by SCS Global Services. For a quick overview, see our snapshot: Fiberon in brief: products, rivals, and EPD coverage.
- Trex remains a heavyweight in composite decking. As of December 2025 we did not find public, product‑specific EPDs for Trex in major registries. See the drill‑down: Trex: product lineup and their EPD reality.
- MoistureShield competes in similar specs. As of December 2025 we did not locate public, product‑specific EPDs for its decking or railing. Details here: MoistureShield: products and EPD coverage snapshot.
Takeaway for project teams is simple. AZEK now matches a key Fiberon advantage on transparency while gaining an edge over Trex and MoistureShield when a product‑specific EPD is a documented requirement. That reduces substitution risk on carbon‑accounted projects, so sales do not hinge on price alone.
What specifiers get now
With TimberTech Advanced PVC Decking carrying an EPD, estimators and sustainability leads can plug verified A1–A3 results into their models without defaulting to generic values that often come with penalties. That small paperwork shift shortens submittal back‑and‑forth and can shave precious time in purchasing cycles. We see this as a springboard, not a checkbox.
Visibility check on AZEK’s site
As of January 28, 2026, we did not find the TimberTech Advanced PVC Decking EPD linked on AZEK’s public sustainability pages. If it is posted behind a portal, consider surfacing a direct link on the corporate sustainability or product literature pages so specifers grab it in two clicks rather than hunting through registries. That single change typically boosts download and reuse rates in proposals.
What to watch next
- More coverage in the same ecosystem. Railing systems, trims, and cladding built from the same materials are common asks in commercial and multifamily scopes. Extending EPDs to those families keeps design intent intact from DD to buyout.
- PCR alignment across portfolios. Picking the same operator and compatible Part B rules where feasible makes portfolio growth faster and audits simpler, especially when several plants feed one family.
Bottom line
AZEK has entered the transparency arena with a June 2025 EPD for TimberTech Advanced PVC Decking, published by Smart EPD. In a category where Fiberon already shows product‑specific declarations and Trex and MoistureShield are still ramping public coverage, this debut puts verified numbers behind a flagship board and opens doors in specs that increasingly ask for them.
