Congrats, VaproShield’s first EPDs land

What VaproShield just published

VaproShield released its first‑ever Environmental Product Declarations in July 2025. Three product‑specific EPDs now cover PanelShield SA, RevealShield SA, and SlopeShield Plus SA in MasterFormat 07 25 00 Weather Barriers. The program operator listed is EPD Hub, and the documents follow ISO 21930 and ISO 14025. Several declarations note third‑party LCA consultant support, while others list development in‑house.

Why it matters for specifiers

WRB and air‑barrier lines show up in a huge share of envelope specs. Without a product‑specific EPD, design teams often fall back to conservative generics in whole‑building LCA tools, which can tilt comparisons away from otherwise competitive products. Publishing here removes that quiet penalty and makes apples‑to‑apples reviews simpler for LEED v5‑minded projects.

Where this puts them competitively

Two category leaders already bring EPDs to the table. DuPont updated its North American Tyvek wrap EPD in July 2025, signaling active transparency on membranes (DuPont press release, 2025). GCP Applied Technologies lists PERM‑A‑BARRIER air‑barrier EPDs verified by NSF with current validity windows (NSF, 2025) (NSF, 2025). Carlisle CCW also shows multiple air‑barrier EPDs in public operator registries as of January 24, 2026. VaproShield’s move puts their core wraps and roof underlayment on that same transparency shelf, which means fewer hurdles in side‑by‑side evaluations.

The scope that matters

These are product‑specific EPDs, not a family average. PanelShield SA and RevealShield SA target wall WRB‑AB applications, including open‑joint rainscreens in the latter. SlopeShield Plus SA extends coverage to vapor‑permeable roof underlayment, a nice fit for mass‑timber and steep‑slope assemblies. That spread matches how buyers actually spec these systems across walls and roofs, so reps can walk into a package bid with real numbers instead of estimates.

Program‑operator context

EPD Hub has leaned into rapid publishing and digital workflows, reporting a 132% increase in published EPDs in 2024, which aligns with faster market cycles for getting verified data in hand (EPD Hub, 2025) (EPD Hub, 2025). That momentum shows up on Friday releases and quick library updates, so teams can point to live, signed PDFs without chasing down stale links.

Company background, briefly

VaproShield manufactures vapor‑permeable WRB, air‑ and vapor‑barrier membranes, plus rainscreen components for commercial, residential, modular, and mass‑timber projects. The brand is known for black, UV‑stable open‑joint solutions and field‑friendly self‑adhered sheets. With EPDs in place, their membrane story now includes verified carbon data, not just performance testing.

Visibility check and quick wins

We found VaproShield’s EPDs listed in their submittal library and sustainability hub. See the EPD documents page and sustainability overview here: EPD Documents and LEED/Declare/EPD. We did not yet see direct EPD links on the PanelShield SA and RevealShield SA product pages. Adding those links near spec downloads is an easy lift that pays back in fewer clarification emails from design teams. Visibility is key, and it’s definately worth it.

What to do next

• Mirror each EPD link on the relevant product page and in every submittal bundle.
• Prep a one‑page cheat sheet that maps each membrane to its EPD and MasterFormat section so estimators do not hunt.
• When choosing partners for future declarations, prioritize teams who handle the data‑collection grind inside your plants. That is what keeps roadmaps on time and lets your engineers stay focused on product instead of spreadsheets.

The takeaway

VaproShield has entered the transparency arena. With three WRB‑AB and roof underlayment EPDs live, they are now spec‑ready against Tyvek‑ and PERM‑A‑BARRIER‑equipped bids, while giving modular and mass‑timber teams a clean, verifiable option for vapor‑permeable systems. That changes the math in close contests.
