DuPont’s building portfolio and its EPD coverage, decoded
DuPont is a rare mix of housewrap icon and insulation heavyweight. If you sell or specify materials, here’s a fast snapshot of what they make for the built environment and how well those lines are backed by Environmental Product Declarations that keep you in play on EPD‑required bids.
Who DuPont is in construction
DuPont’s Performance Building Solutions and Corian Design business covers the building envelope and surface finishes. Think weather and air barriers under the Tyvek name, extruded polystyrene board insulation under Styrofoam, spray foam kits branded Froth‑Pak, polyiso boards like Thermax, plus Corian Solid Surface for counters and casework. Portfolio breadth is wide rather than niche. Across North America and Europe the SKU count lands in the hundreds.
For a broader look at the company’s climate posture and goals, see DuPont’s sustainability hub and recent progress reports (DuPont Sustainability Report, 2025).
What product categories DuPont serves
At a high level, we see coverage across multiple categories that regularly feature in commercial and residential specs:
- Weather‑resistive and air barrier membranes under Tyvek and AirGuard
- XPS board insulation under Styrofoam
- Polyiso board insulation under Thermax
- Jobsite spray polyurethane foam kits under Froth‑Pak
- Solid surface sheets and shapes under Corian
Most teams will touch at least two of these in envelope‑heavy projects. That versatility matters when owners ask to simplify submittals.
EPD footprint in a sentence
DuPont publishes many product‑specific EPDs, predominantly with UL Solutions and IBU, across weather barriers, XPS and polyiso insulation, spray foam kits, and Corian sheets. Coverage is strongest where they are historically category leaders.
Where EPD coverage is strongest
Membranes and wraps are well represented. Tyvek and AirGuard families include multiple current EPDs in Europe, and DuPont announced an updated North American EPD for the full Tyvek wrap range in July 2025 that consolidates commonly specified SKUs (DuPont press release, 2025). In insulation, Styrofoam low‑GWP XPS and Thermax polyiso have current, operator‑published EPDs that specifiers can cite without friction. Corian Solid Surface carries product‑specific EPDs across thicknesses and recycled‑content options, a helpful detail for interiors teams.
A useful marker on decarbonization progress. DuPont reported a 93% reduction in Scope 1 and 2 emissions for the Performance Building Solutions and Corian Design business versus 2019, reflected in its 2025 progress report, which aligns with the low‑GWP refresh of Styrofoam and updates to Tyvek disclosures (DuPont P&BS Sustainability Progress Report, 2025).
Where the gaps likely are
Accessories can be a blind spot. Sealing tapes and some flashing SKUs are widely used with Tyvek systems, yet we could not locate product‑specific, third‑party EPDs for several of these accessories in public operator libraries as of December 8, 2025. That matters because many building teams now score whole envelope packages against LEED v5‑aligned procurement rules, and a missing EPD on an otherwise standard accessory can force conservative assumptions in carbon accounting.
One example. Tyvek Tape is a staple in residential and light commercial weatherization, but we did not find a published, product‑specific EPD for it in the main operator portals. Meanwhile, an alternative from a like‑kind competitor, Pro Clima’s TESCON VANA adhesive tape, has a current EPD in the International EPD System valid through 2029 (International EPD System, 2024). That difference can tip a spec toward a fully documented tape‑membrane package on projects that tally embodied carbon rigorously.
Why this matters commercially
Owners and GCs increasingly treat product‑specific EPDs as table stakes, not nice‑to‑haves. On LEED v5‑targeted projects and corporate builds with supplier transparency policies, products without EPDs often carry a penalty in carbon models. Teams default to pessimistic values, which nudges them to consider similar products that do have third‑party verified data. You stay in the conversation when the entire assembly is covered.
The competitive field DuPont sees most
Expect these names across bids and substitutions by application:
- Air and weather barriers: SIGA, Pro Clima, 3M, Henry by Carlisle, Tremco, SOPREMA. Several publish EPDs for membranes or tapes, for example SOPREMA’s SOPRASEAL LM series carries an EPD download in its documentation (SOPREMA, 2025) and Pro Clima lists EPDs across INTELLO membranes and TESCON VANA tape (pro clima, 2025).
- XPS and polyiso insulation: Owens Corning, Kingspan, Johns Manville, Atlas. Industry EPDs for polyiso are maintained by PIMA and widely referenced in roofing and wall assemblies (PIMA, 2025). Owens Corning has public materials confirming FOAMULAR NGX with third‑party verified EPD coverage and continues to promote EPD‑backed XPS in North America (Owens Corning newsroom, 2020).
- Spray foam kits: Handi‑Foam by ICP, Hilti for firestop foams in specific scopes. These are sometimes swapped for mineral wool or board insulation details when EPDs or VOC documentation do not align with owner requirements.
What DuPont makes in sheer numbers
At the category level DuPont participates in several discrete MasterFormat divisions with product variation by thickness, facer, compressive strength, and recycled content. That translates to dozens of core SKUs and, when size and edge profiles are included, likely hundreds on distributor shelves. A practical takeaway for spec writers is to confirm the exact product name and code that matches the published EPD before the submittal goes out.
A quick playbook to close the EPD gaps
- Start with assemblies, not parts. Map every membrane‑plus‑accessory combination you actively market. Prioritize high‑volume accessories that ride with Tyvek wraps on residential and light commercial jobs, because they win or lose specs quietly.
- Choose the common PCR first. Pick the Product Category Rules your competitors are using, then verify operator acceptance in your target markets so reviewers can compare apples to apples. Where PCRs overlap, follow the one most prevalent in your bid set.
- Publish in the operator your customers search. UL Solutions and IBU are the places most North American and EU‑focused teams check first, then replicate to other directories if needed.
- Refresh on a calendar. Many teams still scramble at renewal. Put expiries on a shared calendar with a 6‑month runway so sales never has to say “we’re waiting on the new EPD.”
The upside if they tighten coverage
Closing the accessories gap would give DuPont a cleaner, all‑EPD envelope story from tapes through wraps to insulation. That simplifies LEED v5 documentation and reduces the risk of substitutions that chip away at share. For teams chasing carbon caps or Buy Clean‑style owner policies, a complete, verified set gets you shortlisted faster and keeps you there. It’s definately the low‑drama way to win the spec.

Frequently Asked Questions
Which DuPont product families commonly appear with published EPDs?
Tyvek and AirGuard membranes, Styrofoam XPS, Thermax polyiso, Froth‑Pak spray foam, and Corian Solid Surface commonly appear with current EPDs published by operators such as UL Solutions and IBU.
What parts of DuPont’s weatherization systems are least likely to have EPDs today?
Based on public operator libraries as of December 8, 2025, several accessories such as certain sealing tapes and flashing SKUs show limited product‑specific EPD coverage compared with wraps and boards. Always verify the exact SKU against the operator listing.
If a product in my assembly lacks an EPD, how risky is that for LEED v5 projects?
Risk varies by owner policy. Many teams assign conservative embodied‑carbon values to uncovered products, which can push them to consider alternatives with verified EPDs. Having an EPD across the full assembly keeps the spec intact and reduces substitution risk.
Which competitors publish EPDs in similar application areas?
Membranes and tapes: Pro Clima and SIGA list EPDs for several products. Air barriers: SOPREMA and Tremco provide EPD‑backed options in parts of their lines. Insulation: Owens Corning, Kingspan, and Johns Manville provide EPDs across XPS or polyiso.
Does the age of an EPD matter for getting specified?
If it is valid, age rarely matters to buyers. The exception is when expirations are near. Keep renewal buffers so sales never has to pause while waiting for a refreshed declaration.
