Congrats, ISOCELL: first‑ever EPDs are live

What ISOCELL just published

In May 2025, ISOCELL released its first‑ever Environmental Product Declaration covering its cellulose blow‑in insulation line. The declaration is product‑family scope and lists multiple cellulose variants, so specifiers get one document that maps to the core SKUs used on roofs, walls, floors, and ceilings. The program operator of record is IBU, aligned to EN 15804 and ISO 14025. It cites the Part B PCR for blow‑in insulation made from cellulose and wood fibres, which fits the application set.

Why this matters in cellulose now

Cellulose competes on comfort and carbon, yet bidding often stalls when verified data is missing at submittal time. A family‑level EPD gives design teams one file to pull into whole‑building LCA tools and removes the default to conservative generic datasets that punish products without product‑specific evidence. Pair that with IBU’s broad recognition across EU public procurement and the needle moves from maybe to yes earlier in the cycle.

ISOCELL at a glance

ISOCELL manufactures loose‑fill cellulose insulation from recycled newspaper and supplies airtightness systems to complete the envelope story. The cellulose is installed by trained blow‑in specialists and is common in energy retrofits and high‑performance new builds. For project teams, the new EPD turns a trusted material into a documented one.

Competitive snapshot, quick take

Closest peers in European cellulose include Thermofloc and CIUR. As of today, their cellulose blow‑in entries in major registries do not show current, product‑specific EPDs. That leaves room for ISOCELL to step forward on transparency in its home material class.

Zooming out to substitutes that show up on the same drawings, fiberglass and mineral wool brands already publish multiple blown‑insulation EPDs in North America. Names like Knauf Insulation and CertainTeed have live declarations for blowing wool segments, which means cellulose wins more head‑to‑head moments when its own data is equally easy to cite. Different material, same spec box.

Scope notes specifiers will care about

The ISOCELL declaration is a product‑family EPD that references multiple branded variants within the same use class. That choice keeps documentation tight without splitting hairs across near‑identical SKUs. The public record does not name a separate third‑party LCA developer. If a future wave adds plant‑specific splits or complements like membranes and tapes, keep the same rulebook to preserve comparability.

Where to find the EPD now

We looked for a direct EPD download on ISOCELL’s product and Downloads pages and did not see it listed alongside datasheets and DoPs. Adding a prominent link on the cellulose product page and the central Downloads hub will reduce submittal friction and help sales avoid back‑and‑forth. Visibility is part of the value. (isocell.com)

Operator pick, in context

Publishing with IBU aligns with how European buyers search and how national databases ingest machine‑readable EPDs. If a North American push grows, consider dual listing through a program operator that U.S. spec teams check first. The right operator is the one your buyers already trust. (epd.guide)

What this means competitively

ISOCELL has joined the transparency arena with a document that meets the standard buyers expect. Against cellulose peers that lack current EPDs, this is an edge. Against fiberglass and mineral wool incumbents that already show blown‑insulation EPDs, it levels the playing field so the conversation can focus on performance, install, and service rather than paperwork.

A practical next move for teams

Make the EPD one click from the cellulose product pages and tuck it into submittal bundles. Set a renewal reminder tied to the PCR update cycle so refresh work never collides with peak bid season. And if collecting plant data felt heavy this round, pick a partner who handles the wrangling so engineers can stay on product. It is definately the calmer way to scale coverage.
