AZEK: product range and EPD coverage, decoded
AZEK sits at the center of premium outdoor living with TimberTech decking and railing plus AZEK Exteriors trim, moulding, siding and cladding. If you compete in these categories or sell into projects that prefer verifiable environmental data, knowing where AZEK has Environmental Product Declarations (EPDs) today, and where gaps remain, helps you plan bids and protect specability without last‑minute scrambles.
Who AZEK is and what they sell
The AZEK Company builds a broad portfolio of exterior materials under TimberTech and AZEK Exteriors. Core lines include PVC and composite decking, deck railing, porch boards, trim and moulding, and increasingly cladding and siding that repurpose deck board tech for facades. It is not a pure play. Think of AZEK as an outdoor platform with multiple product families rather than a single hero SKU.
How wide is the catalog
Across colors, board profiles, lengths, railing kits, trim dimensions, and accessory parts, AZEK likely sells in the hundreds of SKUs. That breadth is a commercial advantage on design flexibility, but it also multiplies the work required to achieve comprehensive enviromental coverage across the range.
Where AZEK has EPDs today
AZEK has a product‑specific, third‑party verified EPD for TimberTech Advanced PVC Decking, issued in 2025 and published by Smart EPD (Smart EPD, 2025). The company also signals EPD availability for TimberTech decking and AZEK and Versatex Trim on its corporate sustainability materials, with EPDs accessible on the Smart EPD site.

Notable gaps to watch
Based on public listings, coverage appears focused on the Advanced PVC Decking and selected trim. Common project asks where we see potential gaps include composite decking lines, cladding systems using deck boards as rainscreen, deck railing systems, and certain siding SKUs. If your product line overlaps those areas and a spec calls for product‑specific EPDs, expect added friction or the risk of being swapped for an alternative that has one.
Why EPD gaps matter in specs
On many commercial jobs, product‑specific, third‑party verified EPDs remove penalties in carbon accounting and smooth submittals. Teams chasing LEED or firm‑level carbon targets often set internal rules that prefer products with published EPDs. Showing up with a current declaration keeps the conversation on performance, aesthetics, and lead time rather than exceptions and substitutions.
Competitive pressure AZEK meets most often
Decking and cladding: Trex, Fiberon, MoistureShield, Envision, Wolf, and Zuri frequently appear in the same bids. Among these, Fiberon publishes product‑specific EPDs across several decking families through SCS Global Services, which can make them spec‑ready out of the box when a project requests declarations.
Trim, siding, and cladding swaps: On facades, fiber‑cement from James Hardie is a common alternative with multiple current EPDs through European and international operators, which can simplify documentation on institutional projects. PVC trim competitors such as Westlake Royal and Versatex often compete feature‑for‑feature, so an EPD can be a tiebreaker when sustainability paperwork is weighted in the scorecard.
A quick play if you sell against AZEK
If a best‑seller in your lineup lacks an EPD and you face TimberTech or AZEK Exteriors, pick one representative SKU per family first, then expand per color or thickness only when the spec mix demands it. That keeps the first wave fast while preserving the option to scale. The right PCR choice matters. Good practice is to align with the PCR used by the dominant competitors in that exact application so reviewers can compare apples to apples.
What would move the needle for AZEK
One EPD per major decking family (PVC and composite), one for railing systems, and one for exterior trim would cover most project requests. A cladding‑specific EPD for rainscreen applications using deck boards would further reduce substitution risk on education, healthcare, and civic work. Smart sequencing and tight data collection are the unlocks here. The faster teams can pull utility, resin, and scrap data from plants, the faster declarations get published and into submittal packages.
Bottom line for 2025 specs
AZEK already has credible coverage on Advanced PVC Decking and signals EPDs for trim, yet material gaps remain in categories that are frequently spec‑critical. Competitors like Fiberon and James Hardie can exploit those openings where EPDs are table stakes. Closing the remaining gaps would let AZEK defend design intent more often and keep the spec intact from DD through buyout.
