Gentek Canada products and EPD coverage in 2026
Gentek is a household name for Canadian exteriors, with deep lines in siding, soffit and fascia, metals, and windows. For teams chasing low‑carbon specs, the real question is simple. Where do Environmental Product Declarations already exist, and where are the gaps that might slow a submittal or knock a product off a shortlist?
Gentek in one glance
Gentek Building Products Co. operates under the Associated Materials umbrella, supplying residential exterior materials across Canada. The lineup spans vinyl and composite siding, aluminum siding, vinyl and PVC soffit and fascia, eavestrough and coil, plus vinyl and aluminum windows, patio and entry doors. It is not a pure play. They compete across several adjacent categories and show up often in single family, low rise multi, and light commercial work.
Product range and scale
Across siding alone Gentek carries multiple families and profiles, with color palettes running wide. Add soffit, fascia, trims, metals, and windows, and the catalog reaches into the hundreds of SKUs. Exact counts vary by region and season, so think dozens per line and hundreds overall rather than a tight number.
What is covered by EPDs today
Two composite and vinyl cladding systems under Associated Materials have current, program‑operator verified EPDs. ALIGN and ASCEND are listed by NSF International with validity through April 15, 2029 (NSF listings, 2024). Gentek’s Canadian ALIGN page even surfaces an Environmental Product Declaration Summary in its technical resources, a helpful signal for specifiers who need documentation on day one.
Where coverage looks thin
Most legacy vinyl siding families, specialty vinyl shakes, aluminum siding, soffit and fascia, rainware, and windows do not show a public, product‑specific EPD as of January 23, 2026. That does not mean EPDs are impossible for these lines. It simply means project teams may default to conservative assumptions when a declaration is missing, which can drag on approvals or push a swap to a product with ready paperwork.

Likely best seller without an EPD, and why that matters
Take a mainstream vinyl siding line like Fair Oaks. It targets broad, price sensitive segments and appears frequently in distributor catalogs. Without an EPD, it risks losing out when owners or GCs prioritize materials with verified declarations, especially on projects aiming for modern sustainability goals where EPD backed products keep submittals moving. No drama here, just practical math that favors documented options.
Who Gentek runs into on bids
Competitors vary by region and building type, yet a familiar cast shows up repeatedly.
- CertainTeed for vinyl siding and polymer shakes, plus broad interiors coverage. They publish product specific siding EPDs.
- Westlake Royal Building Products for vinyl and composite options in similar price bands.
- James Hardie on fiber cement cladding that often subs in for higher impact zones and institutional work.
- KP Building Products and Mitten on vinyl across Canadian channels.
This mix means spec fights do not always stay vinyl versus vinyl. Fiber cement or engineered alternatives appear as substitutes in education, healthcare, and municipal work where durability and documentation carry weight.
The fast path to close the gap
If the goal is to unlock more specifications in 2026, start with one or two high volume SKUs in vinyl siding and one aluminum profile, then expand to soffit and fascia. Pick the prevailing PCR that competitors use for cladding so results compare cleanly. Lock a recent manufacturing year and collect plant data once, wiht a ruthlessly organized request list that covers energy, materials, scrap, and logistics. Good partners will do the heavy lifting on data collection and project management so in‑house teams can stay focused on operations while the EPD proceeds.
A small sustainability signal worth amplifying
Gentek already highlights an EPD summary for ALIGN on its Canadian product page. Link that in submittals and distributor portals so it does not get missed by reviewers. For teams that want a quick hand‑off, point directly to the technical tab on the ALIGN page as your living source.
What this means for specs in 2026
Gentek serves many categories and has momentum in composite cladding with two verified EPDs on the books (NSF listings, 2024). The commercial upside is clearest if marquee vinyl lines add product specific EPDs next. That move turns everyday catalog workhorses into low friction choices on EPD‑required jobs, which keeps bids competitive without racing to the bottom on price. For context and a useful technical doorway, see Gentek’s ALIGN page, which includes an Environmental Product Declaration Summary in the resources section.
Frequently Asked Questions
Does Gentek publish any current, program‑operator verified EPDs for cladding?
Yes. Associated Materials lists two cladding EPDs, ALIGN and ASCEND, verified by NSF and valid to April 15, 2029 (NSF listings, 2024).
Are Gentek’s vinyl siding families broadly covered by EPDs today?
Not broadly. As of January 23, 2026 we do not see public, product‑specific EPDs for mainstream vinyl lines. That gap can slow approvals on EPD‑preferred projects.
Which competitors most often show up against Gentek in siding specs?
CertainTeed, Westlake Royal Building Products, James Hardie, KP Building Products, and Mitten are frequent comparables in residential and light commercial work.
Where on Gentek’s site can specifiers find a sustainability‑oriented resource?
The Canadian ALIGN Composite Cladding page includes an Environmental Product Declaration Summary under Technical Information, which is useful for submittals.
