EPDs for Weather Barriers in Europe: the data guide

What counts as a “weather barrier” here

We use the broad construction sense of weather barrier that includes air and water resistive barriers and related membranes used in wall and roof assemblies. Think housewraps and breather membranes that keep water out and let assemblies dry. Adjacent products such as roof waterproofing sheets are noted where they influence competition.

The market in one view

Over the last five years, 19 current EPDs were published for weather barriers in Europe by 8 manufacturers through 6 program operators, using 7 distinct PCRs. The most recent addition is Kliima’s “Sugar green” issued on Sep 26, 2025 with EPD Hub, valid through Sep 26, 2030 under EPD Hub Core PCR v1.1.

Developer support is the norm. 14 of the 19 EPDs involved an external EPD consultant or service provider, about 74 percent. For manufacturers, that lines up with what we see in fast‑moving categories where teams prefer white‑glove data collection and project management while they keep plant and product work on track.

Year‑by‑year issuance

Volume peaked in 2022, then tapered, with no records in 2024. If you are scheduling a release, the cadence below helps with competitive timing and sales enablement.

Year	EPDs issued
2021	1
2022	10
2023	4
2024	0
2025	4

Who is publishing

Eight manufacturers hold current EPDs. Synwer leads by volume with 7. Kliima follows with 4. Isover Saint‑Gobain appears under two label variants (Isover Saint‑Gobain and SAINT‑GOBAIN ISOVER) with 2 each. Don & Low, Draken i Reftele, SIGA Cover, and Stabila 2 round out the set. Name hygiene matters for searchability and comparability, so it is worth aligning variants before your next filing.

Program operators used (and what that signals)

Six operators show up, but their role differs.

• Kiwa accounts for 7 EPDs, all from one manufacturer. High share, low diversity suggests a single‑portfolio cluster rather than a market default.
• INIES and EPD Hub each carry 4 EPDs. INIES spans 2 manufacturers. EPD Hub’s 4 EPDs come from a single manufacturer, yet its Core PCR v1.1 has the longest runway among current filings.
• EPD International AB has 2 EPDs across 2 manufacturers. IBU and EPD Italy appear once each.

For teams choosing an operator, diversity of participating manufacturers is a useful proxy for what specifiers expect in a region. It also hints at reviewer familiarity with your product type, which can shave weeks off back‑and‑forth.

PCRs: what competitors actually used

Seven distinct PCR references appear. Two stand out for future‑proofing and comparability.

PCR (short label)	EPDs	Latest expiry	Notes
EN 15804 (CEN core rules)	3	Dec 31, 2028	Widely recognized baseline for EU projects.
EPD Hub Core PCR v1.1 (Dec 5, 2023)	3	Sep 26, 2030	Long runway, recent methodology update.
PCR 2019:14 Construction products (EN 15804+A2) v1.3.3	2	Dec 12, 2028	Common Part A reference in Europe.
c‑PCR Flexible sheets for waterproofing (prEN 17388, under development)	1	Feb 21, 2030	Adjacent products may land here.
Part B: False ceiling and underlay sheeting	1	Oct 24, 2027	Niche, check fit carefully.
National addition to NF EN 15804+A1 (FR)	2	Jun 13, 2027	Useful for France‑focused specs.
Unknown PCR	7	Nov 7, 2027	Clean up recommended to avoid buyer confusion.

What this means for your next EPD. If you sell across multiple EU markets, aim for EN 15804 with A2 alignment where possible, or a Core PCR that is already seeing uptake in your competitive set. A PCR is the rulebook of Monopoly, ignore it and the game falls apart. Timing also matters because a PCR update does not invalidate your EPD overnight, but your renewal will need to use the newer rule.

Expiry risk map (next five calendar years)

• 2026: 1 expiry on Jul 22.
• 2027: 10 expiries cluster in June through November, including 7 where the PCR is not clearly recorded. Expect a flurry of renewals and re‑issues that year.
• 2028: 4 expiries, concentrated in June and December, mostly EN 15804 and EN 15804+A2 based.
• 2029: none on the books.
• 2030: 4 expiries tied to EPD Hub Core PCR v1.1 and the c‑PCR for flexible sheets.

If your competitors come up for renewal in 2027, publishing fresh in early 2026 can put you in front of specifiers while others pause to rework LCAs. Sales teams feel that gap fast.

Adjacent products that influence bids

Some waterproofing and dampproofing membranes sit next to weather barriers in bids. For example, Norwegian maker Isola holds current EPDs for roof waterproofing under EPD Norway (NPCR 022 Part B), valid into 2028 and 2029. These are not the same functional class as housewraps, but they do shape buyer expectations on documentation in Scandinavia.

Notable absences in the pan‑European weather barrier set

A few large brands that many buyers ask about do not appear in this Europe‑scoped weather barrier subset as of Jan 21, 2026. This includes Pro Clima (MOLL bauökologische Produkte GmbH), Dörken (DELTA membranes), A. Proctor Group, and Rothoblaas. Some may publish EPDs in other product groups or national databases, or under different corporate entities, but they are not visible here. DuPont publishes Tyvek Air and Water Barrier EPDs with UL that remain valid through Feb 27, 2030, which are frequently referenced in North America rather than EN 15804 contexts.

If your brand is on this list, specifiers may assume a penalty in carbon accounting when an EN 15804 EPD is missing, which can push a project team toward a competitor with a product‑specific declaration.

How manufacturers are using EPD consultants

Roughly three in four filings used an external EPD service provider. That aligns with a practical reality. The heavy lift is clean data from utilities, resin and fiber inputs, coating lines, and packaging. A partner that drives that work inside your org is the real time saver. If you prefer a white‑glove approach that removes internal friction, an EPD service provider like Parq is built around speed, ease, quality and completeness rather than a do‑it‑yourself tool. We also stay program‑operator agnostic so you can publish where your market expects it (IBU in DACH, INIES in France, EPD International AB for pan‑EU use, and so on).

Practical playbook for a 2026 filing

Pick your PCR by looking at your closest competitors and target markets. Validate that your operator has active reviewer capacity for membranes and barriers. Lock a reference year for data and prepare a short prospective period only if the product is brand new. Build your release around sales cycles in your top three countries. Squads that ship in Q2 get two full quarters of bid activity before summer slowdowns. Dont overcomplicate the scope unless a specific customer requires it.

A quick note on standards and credits

Most EU project teams now expect EN 15804‑aligned EPDs. LEED v5 drafts continue to value product‑specific EPDs within material credits, and EU public buyers increasingly reference EN 15804 as the baseline for comparability (CEN, 2019). Where numeric thresholds are mandated locally, always confirm whether a national addition applies in France or similar markets (AFNOR, 2024).

Wrap up, plus how to get the full dataset

This guide is based on the global public registry of EPDs that most architects and specifiers consult. Due to publication and indexing delays, some late 2025 entries may not appear yet.
