What is expiring in February 2027
The expiring record is for CLIMAVER Neto, a self‑supporting glass wool duct panel used to fabricate HVAC supply and return ducts. Scope is product‑specific and aligned to thermal insulation PCRs for duct materials. The validity date on this older declaration is February 27, 2027.
Are replacements already in place
Yes. Isover has newer, product‑specific EPDs covering CLIMAVER Neto and the higher‑fire‑class CLIMAVER A2 Neto that are already published and current. One example is the International EPD System listing EPD‑IES‑0029008:002 for ISOVER CLIMAVER Neto, valid to March 9, 2031, and publicly downloadable. Another is the current International EPD System page for CLIMAVER A2 Neto. You can also find CLIMAVER Neto on Isover’s technical site with links to the EPD PDFs.

What this means for specs and bids
If a project submittal still cites the 2022–2027 CLIMAVER Neto EPD, swap in the newer EPD ID and file. Owners and GCs that require product‑specific EPDs should accept the updated declaration without changing the duct system design. This keeps HVAC packages compliant and avoids last‑minute substitution risk when credits or owner rules hinge on current EPD documentation.
If a gap did appear, who would likely get the call
If coverage were missing, specifiers would likely pivot to HVAC duct insulation systems with current EPDs in similar use cases.
- Owens Corning EcoTouch Insulation for Flexible Duct, used by flex‑duct manufacturers and listed with a current program‑operator EPD.
- Knauf Insulation Atmosphere Duct Wrap Unfaced, a glass mineral wool wrap for external duct insulation with a current declaration.
- Armacell ArmaFlex Airduct or ArmaSound SuperSilence Ductliner, closed‑cell elastomeric or acoustic liners with active EPDs for ductwork.
These are not one‑to‑one substitutes for a self‑supporting duct board system, yet they are common, EPD‑backed duct insulation solutions that often land on shortlists when documentation is required.
Where to find Isover’s EPDs quickly
Start with the product page for CLIMAVER Neto, which includes technical docs and EPD links. For a directory view across program operators, EPD.directory also lists Isover’s CLIMAVER Neto family and related PCRs. (Isover Technical Insulation, 2026) (EPD.directory, 2026).

Timely renewals matter commercially
Project teams increasingly default to products with live, product‑specific EPDs. When data is missing or expired, the carbon accounting can force pessimistic assumptions that make a product less attractive on tight targets. Keeping EPDs current preserves specability, shortens back‑and‑forth at submittal, and protects margin when competitors arrive with cleaner paperwork.
Bottom line for HVAC teams
A single Isover EPD rolls off in February 2027, but CLIMAVER Neto coverage is already renewed on newer declarations. Update submittals now to the latest EPD IDs and PDFs. If a local market needs a different operator or scope, check the available CLIMAVER variants and pick the one that matches the project’s region and PCR version.

Tieing it together
For HVAC ductwork, nothing meaningful falls through the cracks here. The 2027 expiry flags a housekeeping task rather than a scramble. Refresh the EPD references in your spec set, keep a copy of the new PDFs in your submittal folder, and move on to the next line item.
