What’s actually set to expire in December 2026
The Magnetron coated glass on PLANICLEAR or DIAMANT declaration in the International EPD System is valid through 2026‑12‑14. Scope covers sputter‑coated flat glass on Saint‑Gobain’s PLANICLEAR and DIAMANT substrates for architectural glazing. See the program listing and the manufacturer PDF for details (EPD International, 2021) (EPD International, 2021).
We did not find a second Saint‑Gobain EPD with a December 2026 validity date in EC3 on April 21, 2026. A second item referenced by some trackers likely renewed early, moved under a different Saint‑Gobain entity, or shifted scope. If your bid package cites a different document ID, pull the current file to confirm the final validity date.
Is a replacement already live for the same product family?
A like‑for‑like renewal for magnetron coatings on PLANICLEAR or DIAMANT beyond 2026‑12‑14 is not visible today in EC3. However, Saint‑Gobain has current EPDs for magnetron coated glass on ORAÉ, its low‑embodied‑carbon substrate, with validity running into late 2028. That gives specifiers a near‑drop‑in pathway on Saint‑Gobain glass, provided the project accepts ORAÉ as the specified substrate instead of standard clear. Reference the ORAÉ overview and EPD library links here: ORAÉ product page and coated‑ORAÉ EPD (Saint‑Gobain Glass, 2023) (Saint‑Gobain Glass, 2023, EPD International, 2023).
Will specifiers lose EPD coverage in December?
If the PLANICLEAR or DIAMANT coated‑glass EPD lapses without a renewal, teams that require a current, third‑party verified EPD would treat the document as out‑of‑scope for credits and many owner requirements. EPDs are typically valid for five years under EN 15804 rules and the International EPD System’s GPI, after which they must be renewed to remain current (EPD International, 2025).

Competitor options with current EPDs if a gap opens
If a like‑for‑like Saint‑Gobain renewal is not posted before 2026‑12‑14, expect specs to lean toward coated or flat‑glass competitors with fresh declarations:
- Guardian Glass sputter‑coated and unprocessed flat glass, North America, current EPDs renewed in March 2024 and running to March 2029 (UL Solutions, 2024) (UL/Guardian, 2024).
- Pilkington Mirai annealed glass, validity into January 2029 under the International EPD System, widely positioned for low‑embodied‑carbon façade work (EPD International, 2024) (EPD International, 2024).
- Vitro Architectural Glass processed glass, SCS‑verified, valid through March 22, 2028, covering coated and heat‑treated configurations common in IGUs (SCS Global Services, 2023) (SCS, 2023).
These are indicative peers within the same MasterFormat family. Always align on local supply, coating stack performance, and optical targets before proposing an alternative.
Business impact for product and bid teams
A short EPD blackout can snowball. Sales will quietly skip EPD‑required projects, marketing loses proof points, and estimators spend cycles defending exceptions. Renewals keep the door open to LEED v5 materials credits and public‑sector RFPs that call explicitely for current Type III EPDs. The five‑year clock is generous, but the last six months are where schedules slip and data gaps appear (EPD International, 2025).
What to do now if you ship coated glass under PLANICLEAR or DIAMANT
Confirm which SKUs your top 10 customers actually specify and map them to the exact EPD IDs in their submittals. If the December‑dated declaration still anchors those bids, start the renewal workstream now. If customers are already pivoting to ORAÉ, align marketing claims and cut sheets so submittals match the coated‑ORAÉ EPDs one‑to‑one. Keep your internal reference year data tidy so verification doesn’t drag on and cause a gap.

The takeaway for spec and sustainability leads
Treat December 2026 as a soft deadline. One Saint‑Gobain coated‑glass EPD definitly times out on 2026‑12‑14, and a rumored second December item does not appear in EC3 today. Either renew PLANICLEAR or DIAMANT coated‑glass coverage on time or align bids to the already‑current ORAÉ coated‑glass EPDs. That keeps your sales path clear and your product submittals clean.
