Gypsum board PCRs, decoded

PCRs for gypsum boards in plain English

A PCR is the rulebook of Monopoly. Ignore it and the game falls apart. For gypsum boards, the PCR defines the functional unit, stages to model, which impact indicators to report, and what scenarios are allowed so your EPD can be compared apples to apples.

Two reference standards sit behind nearly every gypsum board PCR. ISO 14025 governs how Type III EPDs are created and maintained. EN 15804 or ISO 21930 provide construction‑product specifics that PCR authors build on.

Who publishes what, where

North America typically uses a “PCR for Gypsum Panel Products” under operators such as UL, ASTM International, NSF International, and Smart EPD. Many branded and industry‑wide drywall EPDs cite one of these documents today.

Europe sits on EN 15804. You will see Part B PCRs for plasterboard from IBU and EPD Hub, plus country or operator variants that align to the same core rules. A cross‑sector c‑PCR for gypsum‑based construction products has also been under development in the EN system, which some operators reference as they transition.

If your team sells in multiple regions, choose a program operator and PCR that match where specifications and credits are pursued. Being comparable to peers in that market matters more than theoretical purity.

Functional unit and declared product

Most gypsum board PCRs define the product as factory‑made boards used for walls, ceilings, shaftliner, or exterior sheathing. The functional unit is usually one square meter of board at a stated thickness with declared performance classes. If your portfolio spans Type X, Type C, moisture‑resistant, glass‑mat, and abuse‑resistant boards, the PCR will tell you whether a family EPD with variants is acceptable or whether separate EPDs are needed.

Which life‑cycle stages to model

Expect cradle‑to‑gate A1 to A3. Many PCRs allow or require A4 transport, A5 installation, selected B use‑stage scenarios, and C end‑of‑life. Under EN 15804+A2 you must report 13 core environmental indicators so results line up across brands (CEN EN 15804+A2, 2019). EPDs are generally valid for five years before review or renewal, which should be planned into your roadmap to avoid expiries mid‑bid (ISO 14025, 2024).

Data that actually moves the number

Think of the gypsum board factory as a playlist. Change the loudest tracks first.

• Gypsum source split by mass and moisture content, natural vs synthetic FGD.
• Calcination and dryer fuels by energy and higher heating values.
• Board density, weight per square meter, and line speed.
• Paper facers by grade, supplier region, and recycled content.
• Internal recycle loop, edge‑trim and board break rates.
• Electricity mix at plant and quarry, on site generation if any.
• Inbound raw material and outbound finished goods logistics.
• Installation waste and end‑of‑life scenarios allowed by the PCR.

Solid primary data here shortens verification and avoids rework later.

Picking the right PCR without second‑guessing

Start with the geography where you compete. Next, scan competitor EPDs and note the PCR, operator, and version. Aligning with the common PCR in that market increases comparability and reduces questions in review. Check the PCR’s revision date and whether it points to EN 15804+A2 or ISO 21930. Then confirm whether the operator accepts your preferred verifier and whether digital publication timelines match your launch window.

Finally, pressure‑test scope. If exterior sheathing or shaftliner is in play, make sure the PCR’s product defintion covers those subtypes or allows a family approach.

What if the exact PCR seems missing

Operators often offer a generic building products PCR that allows plasterboard as a subcategory. This is a valid on‑ramp when a gypsum‑specific Part B is being revised. Some manufacturers also collaborate through trade associations to refresh or create a gypsum‑specific Part B when market needs shift. It is rare you must invent from scratch.

Verification, publication, and timing

Operators will require third‑party verification before publication. Plan backward from bid dates so there is time for data collection, modeling, internal review, verification, and operator checks. Keep your bill of materials, monthly energy data, and production volumes organized by reference year to avoid scrambles late in the process. Renewals are faster if you preserve that thread across years.

The phrase you might be looking for

Yes, the wording “PCR for gypsum boards” or “gypsum panel products PCR” is what most declarations in this category will cite. Use the operator and version as your North Star in all templates, from the goal and scope to the declared unit section.

Your next right step

Pick the market, pick the operator, then lock the PCR version and build your data plan against it. Treat the PCR like a spec sheet and your EPD writes itself. If internal bandwidth is tight, work with a partner who can own the hunting and gathering so engineering and plant teams stay focused on production. The result is a clean, comparable gypsum board EPD that lands on time and holds up under review.
