Curtain wall EPDs in the United States, a data guide
Planning a curtain wall or glazed façade EPD in 2026? This market snapshot shows who is publishing, which PCRs they use, and where expiries cluster so you can time renewals and position products to win specs. The data reflects current public registry records for the United States, with the latest curtain wall EPD appearing on Nov 14, 2025.
The 2026 snapshot at a glance
Curtain wall EPDs remain a focused but active niche. Across the United States, there are 17 current EPDs from 9 manufacturers, issued through 4 program operators and based on 8 distinct PCRs. The most recent entry is Hydro Building Systems Curtain Wall and Facade Systems Implemented with Hydro CIRCAL 75R, published Nov 14, 2025 by EPD Hub under EPD Hub Core PCR v1.1 and valid to Nov 13, 2030.
Why this matters commercially is simple. When owners and design teams must report embodied carbon, a product without a product‑specific EPD often carries a penalty in models and specs. With an EPD, your system is in play on more projects and you do not have to compete on price alone.
Who is publishing, and how much
Nine manufacturers hold current EPDs in the category. Kawneer leads with 4. Arcadia Inc., EFCO Corporation, Permasteelisa North America, YKK AP America, and Allegion each have 2. Hydro Aluminum, MiTek Inc., and Saint‑Gobain North America each show 1. Together this forms a representative cross‑section of unitized and stick‑built curtain wall producers, plus adjacent façade system brands.
Program operators show healthy diversity. UL accounts for 8 EPDs across 3 manufacturers. ASTM International hosts 5 across 3 manufacturers. EPD Hub has 3 across 2 manufacturers. Smart EPD LLC shows 1 across a single manufacturer. No single operator monopolizes the category, which keeps publishing options open for new entrants.
Issue cadence over five years
Momentum peaked in 2021 and has settled into a steady rhythm. Here is the year‑by‑year view for current EPDs.
| Year | EPDs issued |
|---|---|
| 2021 | 6 |
| 2022 | 4 |
| 2023 | 3 |
| 2024 | 2 |
| 2025 | 2 |
If you are timing a first release, this cadence suggests there is still room to stand out with a well scoped system EPD in 2026.
PCRs in play, from broader to bespoke
Think of a PCR as the rulebook of Monopoly. Ignore it and the game falls apart. The category uses eight PCRs, ranging from broad construction part A frameworks to very specific “curtain walling” part B documents.
The most commonly seen rulebooks in current US declarations are the European‑origin Part B texts for curtain walls. Five EPDs cite Part B: Requirements on the EPD for Self supporting facade elements based on glazed curtain walls. Two more use Part B: Requirements on the EPD for Curtain Walling. These have expiries clustering on Oct 1, 2026 and Jul 1, 2027, with additional items on Dec 1, 2027.
On the North American side, legacy Earthsure Windows 30171600 and Earthsure cradle‑to‑gate references appear across multiple 2021 to 2023 EPDs, expiring Mar 14, 2028 and Jun 11, 2028. EPD Hub Core PCR v1.0 supports two EPDs expiring Apr 12, 2029. The newest footprint is EPD Hub Core PCR v1.1, visible in the Nov 2025 Hydro Building Systems EPD, with a long runway to Nov 13, 2030. Smart EPD Part A v1.0 appears in one EPD with expiry Mar 3, 2030.
What this means for a 2026 project is straightforward. If you are starting from scratch, favor a PCR that will remain stable through your first renewal cycle, and align with what competitive systems use so your numbers compare apples to apples.

The expiry cliff to watch
Renewal timing affects sales pipelines, so plan ahead. Looking five years out, 6 curtain wall EPDs expire in 2026. Another 4 expire in 2027. Three more age out in 2028. Two expire in 2029, and 2 in 2030. The earliest 2026 expiries arrive in April for older window and Earthsure references, followed by a block in October for self supporting glazed curtain wall part B items. Start renewal scoping 9 to 12 months ahead of those dates so submittals never stall.
A simple rule of thumb helps. If your EPD sits within six months of expiry, specifiers may ask for a renewal plan during pre‑submittals. Having draft LCA updates ready keeps projects warm and avoids substitution risk.
How much are EPD consultants involved
Sixteen of the seventeen current curtain wall EPDs list an external EPD service provider or consultant. That aligns with what we hear in the market. Teams want speed and complete data capture without pulling engineers off core work. If you prefer a white‑glove path, an EPD service provider like Parq handles data requests, LCA modeling, and operator coordination while your product and operations teams stay focused on production.
Program operator choices, decoded
UL and ASTM are the two most common homes for curtain wall EPDs in the US. Both are well understood by procurement teams and plug neatly into design tools. EPD Hub is gaining visibility, including the latest Hydro Building Systems EPD grounded in CIRCAL 75R content. Smart EPD shows up once in this category, although it is frequently used for other product families.
Operator selection tends to follow three checks. Does the operator support the PCR you plan to use. Does the operator’s process fit your internal review calendar. Do your top specs show a clear preference in prior submittals. If all three align, you are set.
Manufacturers to watch
- Kawneer remains the volume leader by current count, which often translates into smoother renewals since internal teams already know the drill.
- EFCO Corporation, YKK AP America, Arcadia Inc., and Permasteelisa North America show consistent publishing, which suggests curtain wall EPDs are now table stakes for national and large regional bids.
- Hydro Aluminum’s Nov 2025 entry highlights recycled billet strategies like Hydro CIRCAL 75R being brought directly into system‑level EPDs. Expect more recycled‑content storytelling inside façade system declarations.
Notably absent or adjacent
Based on the public registry as of Jan 17, 2026, several sizable US market names are not showing current curtain wall system EPDs.
- Oldcastle BuildingEnvelope (OBE). No current curtain wall EPDs are visible under their corporate domains. If OBE has published, it may be under a different category or entity, so do check internal libraries before bid day.
- Tubelite. No current curtain wall EPD appears under Tubelite. Other Apogee brands do show activity, including EFCO and Wausau.
- C. R. Laurence. No curtain wall EPD found. Many CRL entries focus on hardware, glazing, and storefront solutions.
- Wausau Window and Wall Systems. A current fixed window EPD is visible, but not a curtain wall system EPD. If you compete head‑to‑head, this gap can be decisive on projects that require curtain wall declarations.
- Schüco. Group‑level EPDs for aluminum profiles are published in Europe and are sometimes referenced by US teams, yet a US curtain wall system EPD is not visible in the registry.
If your brand sits on this list and you are preparing a 2026 release, locking scope now can let sales invite EPD‑required projects back into the pipeline by summer. It’s definately worth a quick internal check on publishable data maturity before you set dates.
Choosing the right PCR for your next EPD
Start with the competitive map. If most peer systems reference a specific Part B for curtain walling, match it so results compare cleanly. Confirm the part A framework your operator will pair it with, since that choice can affect background datasets and end‑of‑life assumptions. Pick a reference year that reflects stable operations and electricity procurement, then document improvements you expect before renewal.
Teams sometimes ask whether to wait for a brand‑new PCR. Waiting rarely pays off. You can publish now on a widely used rule set, then update at renewal if a superior rulebook arrives.
How to move fast without breaking things
Speed and quality are not opposites. Treat data collection like a product launch. Name a cross‑functional lead. Tie plant utility pulls to month‑end close. Align product BOMs to the exact system variants you will sell and specify. Ask your service provider for a weekly burn‑down report so leaders see blockers and remove them early. Good rhythm beats heroics every time.
One last note, and how to get the full dataset
This guide is built on the global public registry of EPDs that most architects and specifiers use. Because of loading delays, some EPDs from the last half of 2025 may not appear yet even if they have been issued.
