Congrats, Industrial Nature: first EPD for IndiTherm
Natural‑fiber insulation is having a moment, and verified data decides who gets shortlisted. Industrial Nature just put numbers behind the narrative with its first Environmental Product Declaration for IndiTherm. That unlocks easier like‑for‑like comparisons in bids and removes the default‑factor penalty that quietly edges products out of specs. Here’s what went live, who verified it, and how the competitive math shifts from here.
Who Industrial Nature is, in one sentence
Industrial Nature, trading as IndiNature, manufactures bio‑based insulation made largely from UK‑grown hemp for residential and commercial projects in the UK and beyond.
What they just published
In April 2025, Industrial Nature released its first EPD covering the IndiTherm flexible hemp‑fiber batt insulation. The declaration is product‑specific and published with the International EPD System operated by EPD International AB. The LCA and documentation were prepared by Renuables, with verification noted in the record. It is current through April 2026.
Why this matters in specs and bids
A current, third‑party verified EPD swaps conservative default factors for measured impacts, which helps design teams compare apples with apples and keep shortlisted products in play. The International EPD System’s footprint keeps growing, with more than 18,000 valid EPDs reported and 9,395 new EPDs published in 2025, a clear signal that transparency is now table stakes, not window dressing (EPD International, 2025).

Product scope at a glance
IndiTherm is a flexible, low‑density batt with thermal and acoustic performance suitable for walls, roofs, and floors. The EPD follows EN 15804 and ISO 14025 conventions and documents cradle‑to‑grave impacts so project LCAs can drop it straight into models without guesswork.
Program operator context
The declaration is listed with the International EPD System. If your buyers work across Europe, this operator is widely recognized and integrates smoothly with national databases and LCA workflows. For readers new to the logo and process, here is our plain‑English primer on the program operator behind it: International EPD System: A Manufacturer’s Field Guide.
Competitive snapshot in thermal insulation
The closest peers in natural‑fiber and low‑embodied‑carbon insulation already show activity. Thermafleece, a UK supplier of wool and recycled‑fiber batts, has current EPD coverage across key SKUs. Wood‑fiber leaders like Gutex publish multiple current declarations through European operators. In North America, Havelock Wool appears without a current, publicly listed EPD today. Net effect for specifiers is simple. Industrial Nature has entered the transparency arena and now competes on documented performance rather than claims.
Visibility check on their site
Good news for specifiers. The IndiTherm product page hosts a direct "Environmental Product Declaration" download, so teams can grab the PDF without email back‑and‑forths. Share this link on line cards and partner portals to reduce hunting: IndiTherm EPD on indinature.co. Consider also mirroring it in a central Resources or Sustainability page so buyers do not have to click through individual products.
Timing note most teams miss
The EPD was issued in April 2025. If it only surfaced in aggregator directories later, that is normal. There is often a lag of weeks to months between program‑operator issuance and global directory visibility. Shrinking that delay keeps live tenders from slipping. If you want playbooks to get new EPDs listed within a day or two next time, reach out to the author. We can share a tight checklist that your team can run with.
What to watch next
Two moves will amplify the impact. First, expand coverage to sister lines like sound‑attenuating or blown‑in formats so more bids can carry product‑specific data. Second, align renewal timing with marketing pushes and new formats to keep momentum. Given market interest in natural‑fiber solutions, moving fast here is definately worth it.
