Congrats JSP: first construction EPD lands

What JSP just published

JSP Corporation has introduced a new, product‑specific EPD for STYRODIA BLOCK DX, described as an extruded expanded polystyrene lightweight fill for civil engineering. It is published with the program operator EPD Hub and went live in July 2025.

The product scope in one look

The declaration covers a lightweight fill block used to form roads on soft ground and similarly constrained sites. Think of it as swapping gravel for a structural marshmallow that holds its shape under load. The scope reads as a product family rather than a single SKU, which fits how geofoam is specified across densities on projects.

Where this sits in JSP’s portfolio

STYRODIA’s entry builds on EPP transparency already in market. JSP’s ARPRO EPP has two current EPDs in the International EPD System, and JSP also lists a construction EPD for MiraFoam with EPD Hub. That brings JSP to at least three current EPDs across foam families (EPD International, 2021 and EPD International, 2023 and EPD Hub, 2024).

Why it matters now

Many owners and DOT‑adjacent projects are tightening embodied‑carbon accounting, and teams increasingly prefer product‑specific EPDs that follow ISO 14025 and EN 15804 because they drop straight into LCAs without guesswork (EPD International, 2025). This new EPD moves STYRODIA from “tell me” to “show me” territory, which can shorten the back‑and‑forth in submittals.

Competitive snapshot

Atlas Molded Products markets EPS board insulation with EPD resources available on product pages, and also promotes a geofoam line for lightweight fill. Their public pages surface an EPS‑IA EPD rather than a geofoam‑specific one at the time of writing, which still helps documentation on envelope work but leaves a gap for fill‑block comparisons in some bids (Atlas Molded Products, 2025).

Insulfoam and Plasti‑Fab actively sell EPS geofoam for structural lightweight fill. We did not find product‑specific geofoam EPDs linked on their current U.S. pages as of January 23, 2026, which means project teams may default to conservative generics when specific data is missing (Insulfoam, 2026 and Plasti‑Fab, 2026).

In Europe, BEWI holds multiple EPS insulation EPDs verified by EPD Norway, including country‑specific variants, signaling strong transparency coverage across its catalog (EPD Norway, 2025).

Commercial takeaway

JSP has entered the transparency arena for civil and infrastructure fill. In North America, that helps STYRODIA compete on documented impacts where product‑specific EPDs often edge out averages in whole‑building and infrastructure LCAs. On envelope work, JSP’s ARPRO and MiraFoam declarations already keep conversations moving when buyers ask for proof over promises.

Visibility check on JSP’s site

We looked for the July 2025 STYRODIA EPD on arpro.com and jsp.com and did not find a public link. The ARPRO EPP EPD is referenced in news posts on arpro.com, but the new civil lightweight fill declaration is not obvious. Adding a dedicated EPD hub on the corporate site and cross‑linking from product pages will make specs faster to land and easier to maintain going forward. It’s a small web task with outsized ROI on bids.

What to do next

Extend coverage to the commonly specified density grades that show up on public works packages. Mirror the EPD on a simple “Environmental Declarations” page and in STYRODIA datasheets so estimators can grab it in two clicks. Then brief sales on when to lead with a product‑specific EPD versus an association average in adjacent categories. That one tweak can be the difference between staying in the schedule of values and getting swapped out last minute. It’s definately worth it.
