Flat Glass EPDs in the US: The Data Guide
The 2026 state of play for flat glass panes, float glass, and architectural glazing in the United States. We combed the public EPD registry most specifiers use and translated the moving parts into a practical roadmap you can act on this year.
The 2026 snapshot in one read
Flat glass manufacturers in the US published 28 currently valid product‑specific EPDs over the last five years. Those came from 5 manufacturers, issued through 4 program operators, and based on 4 distinct PCRs. The most recent EPD in the dataset was issued by Vitro Architectural Glass on Mar 12, 2024 through SCS Global Services using the NGA Flat Glass PCR and is valid until Mar 16, 2028.
Every one of these 28 EPDs lists an external EPD consultant or service provider. If you are building your first glass EPD, plan on partnering with a specialist. It saves weeks of internal back‑and‑forth.
Who is publishing EPDs today
Pilkington leads with 14 EPDs. Saint‑Gobain GLASS follows with 8. Vitro Architectural Glass holds 3. Guardian Glass shows 2. Vetrotech Saint‑Gobain appears with 1, focused on fire‑rated glass. The picture is concentrated but not a monopoly. For search terms, you will also see these under float glass, monolithic glass, and glazing panes.
What this means if you make flat glass: buyers can already compare multiple branded EPDs on broadly similar rulesets. If your product line is missing, you risk being filtered out early when project teams pre‑screen for product‑specific EPDs.
Program operators US teams choose
Four operators appear in the US flat glass set. EPD International AB hosts 16 EPDs across 3 manufacturers. Smart EPD LLC lists 7 EPDs from a single manufacturer. SCS Global Services carries 3 from one manufacturer. UL appears with 2 from one manufacturer. That mix shows both breadth and some one‑to‑one pairings. Operator choice affects template, review cadence, and publishing speed. The best choice is often the one most competitors already use, unless you have other priorities like portfolio scale or multilingual publishing.
The PCRs that matter in 2026
Two rulebooks dominate. The EN‑anchored c‑PCR for flat glass products used in buildings and construction works shows the highest count. The NGA Flat Glass PCR (UN CPC 3711) is the second workhorse and aligns neatly with North American practice. Less common entries include a Core PCR and one EPD filed under a generic EN 15804 reference plus a single unknown PCR. PCR selection sets scope and comparability, so match your main competitors unless there is a strong reason not to.
PCRs used and latest expiries
| PCR | EPDs | Latest expiry |
|---|---|---|
| PCR 2019:14‑c‑PCR‑009 Flat glass products used in buildings and other construction works (EN 17074) | 14 | Jan 23, 2029 |
| Product Category Rule for Environmental Product Declarations NGA PCR for Flat Glass (UN CPC 3711) | 11 | Mar 1, 2029 |
| Core Product Category Rules | 1 | Feb 25, 2029 |
| CEN standard EN 15804 | 1 | Oct 13, 2026 |
| Unknown PCR | 1 | Mar 1, 2029 |
A PCR expiring does not instantly invalidate an already‑published EPD. It simply means the next renewal must align to the updated rulebook. Plan your refresh window accordingly.

Release pace since 2021
Issuance has spiked, then steadied. The registry shows a single release in 2021. A jump to 16 in 2023. Eleven more in 2024. No entries are recorded for 2022 or 2025 in this set. The curve suggests competitive activity concentrated around 2023 and 2024, which tracks with a broader wave of material EPDs entering specs.
EPDs issued per year
| Year | EPDs issued |
|---|---|
| 2021 | 1 |
| 2022 | 0 |
| 2023 | 16 |
| 2024 | 11 |
| 2025 | 0 |
Renewal cliffs to watch
The next five‑year horizon is manageable if you schedule early. Only 1 EPD expires in 2026. None in 2027. The first busy year is 2028 with 17 expiries across the EN 17074 c‑PCR and the NGA Flat Glass PCR. Another 10 roll off in 2029 spanning the NGA PCR, the c‑PCR, one Core PCR, and a single unknown. Nothing lands in 2030. If your EPD aligns with those clusters, budget time 6 to 12 months before the date on the cover.
Consultants are doing the heavy lifting
All 28 EPDs in this category list an external EPD consultant or service provider. That mirrors what we see in practice. Manufacturers want speed, a light touch on internal teams, and dependable review outcomes. An experienced partner handles data wrangling, site questionnaires, and program operator coordination. If you want a simple, high‑quality path, consider an EPD service provider like Parq that pairs efficient data collection with white‑glove delivery.
Notable moves and gaps among big US names
Cardinal Glass Industries now shows 3 current EPDs, including a Flat Glass declaration valid until Jan 15, 2031. That is a meaningful shift for residential and mixed‑use glazing supply in 2026. It also raises the bar for competitors who sell into window fabricators.
AGC Glass North America does not appear with a current US flat glass pane EPD in the public registry as of Jan 22, 2026. If AGC supplies your projects, confirm whether a product‑specific declaration exists under a different category, or plan for project teams to substitute with brands that publish today.
How to pick the right lane in 2026
If your competitors cluster on the NGA Flat Glass PCR, follow that rulebook to keep comparisons clean. If they cite the EN 17074 c‑PCR, match it unless your products target a different use case. Choose a program operator familiar to your specifiers and verifier. Aim to refresh well ahead of the 2028 wave of expiries so reviews do not stack up.
One more tip. Use 2024 operations data if your 2025 record set is incomplete. It is better to publish an EPD with solid, auditable data than wait another year. When your throughput changes or you add a coater line, you can schedule an update that reflects the new baseline.
Data notes and how to go deeper
This analysis uses the global public registry of EPDs that most architects and specifiers rely on. Due to loading delays, some EPDs from the second half of 2025 may not yet appear.
