What is expiring and when
As of 21 May 2026, EC3 shows a set of Knauf UK/I gypsum boards with EPDs maturing on 23 January 2027. Grouped by product family, the eight affected lines are:
- Fire Panel (12.5 mm and 15 mm)
- Performance Plus 12.5 mm
- Moisture Panel 12.5 mm
- Sound Panel 12.5 mm
- Soundshield Plus 12.5 mm
- Windliner 12.5 mm gypsum sheathing
- Core Board 19 mm for shaftwall systems
- Wallboard, Baseboard and Plank in multiple thicknesses
These are EN 15804 EPDs under The International EPD System. Several earlier issues used A1 rules, while others already moved to A2, which matters at renewal because impact indicators and reporting sharpen under A2.
Are replacements already live
Knauf’s own UK site states that all UK produced plasterboard EPDs have been renewed and that the new set shows a material CO₂ reduction versus the previous generation. See Knauf Gypsum’s sustainability hub for the announcement and links to the files, plus an explainer for specifiers: Knauf Gypsum sustainability and Understanding EPDs. We also found new PDFs published in 2026, for example Performance Plus, that cite PCR 2019:14 v2.0.1 with a gypsum c‑PCR reference, aligning to EN 15804 A2 (sample Knauf EPD PDF).
If your internal libraries or procurement portals still surface the 2022 issues, update the bookmarks now. The risk window is not the technical renewal itself. It is findability for busy specifers.

What specifiers will see in common databases
Many teams check EC3 first when assembling submittals. New EPDs sometimes lag in third‑party directories during indexing or mapping to the exact product names users search. If the renewed Knauf files are not yet visible in your go‑to portal, point project teams to the Knauf sustainability page above or to the operator library. For legacy context, the earlier Core Board listing remains in the Environdec library here (EPD International record).
If a visibility gap persists, who stands to gain
Comparable plasterboard products with clearly current EPDs are easy to find, which is why timely publishing matters commercially.
- British Gypsum Gyproc FireLine 12.5 mm has validity through 10 March 2029 under the International EPD System. This competes head‑to‑head with Knauf Fire Panel 12.5 mm.
- British Gypsum Gyproc SoundBloc 15 mm is valid through 10 March 2029 and maps well to Knauf Sound Panel use‑cases.
- British Gypsum Gyproc Moisture Resistant 15 mm runs until 15 January 2030 and is a direct alternative to Knauf Moisture Panel.
- James Hardie Europe fermacell gypsum fibre board stays current to 16 October 2027 and can substitute standard wallboard or heavy‑duty applications where fibre‑reinforced boards are acceptable.
Those dates are sufficient for most public and private tenders now moving on LEED v5 style material credits that require product specific EPDs, not just generics. EPD validity is normally five years under program operator rules, so teams expect a clean runway when they select a board for multi‑year frameworks (EPD International, 2025).
Renewal mechanics that matter this cycle
Think of A2 as the upgraded rulebook. It keeps the playing field fair by expanding indicators and clarifying carbon accounting. If your last EPD was A1, the renewal must use A2 aligned PCRs, which can shift reported numbers. That is normal and, when documented clearly, builds trust. For a refresher on A2’s indicator set and reporting quirks, this plain‑English primer helps (EPD Guide, 2025).
Practical moves to protect specification
Two actions close most gaps fast.
- Publish updated PDFs on a stable, public URL and reference the exact product names that estimators type into search boxes. Consistency wins.
- Coordinate with your operator and the major databases so the new EPD IDs are mapped to your SKUs. A short checklist and a single owner keep this tidy.
If your product marketing team has not prepared fresh submittal packs with the new EPDs, prioritize that now so sales can share a single, definitive link in every quote. Small housekeeping. Big impact.
What this means for bid outcomes
When current, product‑specific EPDs are one click away, your boards are eligible without penalty in most low‑carbon procurement screens. When documents are missing or appear expired, estimators will often choose a comparable board with a live EPD because it avoids extra paperwork or conservative default factors. The cost of an EPD is quickly offset by a single mid‑sized project win, and the admin lift to keep links current is minor compared with the revenue risk. It is definately worth the hour to align systems before autumn.
Bottom line for Knauf UK/I watchers
The eight plasterboard families above hit a renewal date of 23 January 2027. Knauf indicates the replacements are already published and A2 aligned on its UK site, which means specifiers should not lose access to valid data if they look in the right place. Close the loop by ensuring those fresh EPDs are mapped in your preferred databases, because visibility is what keeps a trusted board in the spec. And yes, set a five year timer on the new set too [(EPD International, 2025)].
