Congrats, Visqueen: first EPDs land for membranes and DPC

What Visqueen published

Visqueen released its first wave of EPDs starting in August 2025, then added more in September and November. The set covers three cornerstone lines many projects ask for by name:

• Vapour control layers: Visqueen Vapour Barrier and Vapour Check captured together under one declaration, covering the 300 micron and 125 micron AVCL family scope.
• Ground gas protection: Visqueen Radon R400 Membrane as a product‑specific declaration.
• Damp proof courses: Visqueen Zedex Non‑Combustible DPC as a product‑specific declaration.

All three are published with EPD Hub under the EPD Hub Core PCR 1.1, giving designers a clear, comparable rulebook for A1–A3 and beyond. The first EPD in the set went live in August 2025, with two more following that fall.

Why the categories matter right now

AVCLs, radon membranes, and DPCs sit in the critical path of envelopes and slabs. When a product lacks an EPD, project teams often model with conservative defaults that can push a material out of contention. With these declarations in hand, Visqueen reduces that risk and keeps price from becoming the only lever. It’s the difference between playing with a taped‑over stat line and playing with a full box score.

Program operator and scope notes

• Program operator: EPD Hub using its Core PCR 1.1 (EN 15804 A2 aligned). That common baseline helps apples‑to‑apples reads across competitive membranes and barriers.
• Scope nuance: the Vapour Barrier EPD covers a family of AVCL products rather than a single SKU. That’s useful where a spec alternates thickness without changing the system intent. The Radon R400 and the Zedex Non‑Combustible DPC are product‑specific, which many public clients prefer for audit trails.

Competitive snapshot in membranes and barriers

Here is how the field looks for closely competing categories, based on EPDs visible from major operators:

• SIGA Cover AG has EPDs for Majrex and Majpell vapour control layers with IBU. That means established AVCL coverage in the channel, so Visqueen’s AVCL family EPD closes a real gap rather than inventing a new requirement.
• DuPont’s Tyvek air and water barrier systems are covered by program‑operator EPDs and widely referenced by specifiers, so transparency expectations extend to walls and wraps across many markets.
• Dörken Systems lists membrane underlay EPDs with EPD Hub. While underlays differ from AVCLs and DPCs, the presence of membrane EPDs in the ecosystem raises the bar across adjacent categories.

Net read for buyers and estimators. Visqueen has entered the transparency arena where key rivals already show their numbers, particularly on AVCLs and wraps. That lets teams compare on performance and logistics instead of only on list price.

Company context in one minute

Visqueen manufactures building membranes for housing, commercial, and civil projects, with a portfolio spanning damp proof courses, radon and gas barriers, vapour control, and site protection films. These product lines are often bundled with groundworks or envelope packages, so a single missing EPD can slow a bid even when the rest of the bundle is compliant. Publishing here is timely and definately commercially relevant.

Website visibility check

We found the Zedex Non‑Combustible DPC EPD live on Visqueen’s site in the product downloads. It is published by EPD Hub in 2025 (EPD Hub, 2025). As of January 19, 2026, we did not locate the Vapour Barrier or Radon R400 EPDs on the site’s product pages. Adding those PDFs to each product’s Downloads section will help sales teams and specifiers surface them faster. Visibility counts when submittal windows are tight.

What this changes in specs and bids

• Faster pre‑qual and substitution approvals. Teams can attach a third‑party verified EPD instead of emailing back and forth about proxies.
• Cleaner portfolio storytelling in pursuits. A consistent operator and PCR make the set easier to defend across multiple product lines.
• Better insulation against last‑minute swaps. When projects track embodied carbon, products without EPDs often carry a penalty in models. Having an EPD removes that handicap so the product competes on merit and availability.

Quick next steps for the manufacturer playbook

• Ensure every product page that now has an EPD includes the PDF in the Downloads and Third‑Party Certification sections. Mirror the file naming convention that already works on Zedex DPC.
• Brief channel partners and estimators with a one‑pager linking all three EPDs. That keeps them out of inbox archaeology during bid week.
• Track competitor updates quarterly. AVCLs and wraps are active categories for EPD publishing, so keeping parity prevents surprise hurdles in public tenders.

The takeaway

Visqueen’s August 2025 debut puts verified numbers behind three high‑leverage building‑envelope lines. In a category where several peers already publish, this looks like a smart catch‑up that removes friction and expands the set of projects willing to consider the brand. That is how transparency turns into spec wins.
