ISOVER: two EPDs set to lapse February 2027

What is expiring, and when

As of June 20, 2026, EC3 shows two SAINT‑GOBAIN ISOVER declarations reaching end‑of‑validity in February 2027. One is CLIMAVER Neto, a pre‑insulated glass‑wool duct board used to fabricate HVAC ductwork, published with The International EPD System and valid through 2027‑02‑27 (EPD International, 2022). The second sits in the same HVAC duct panel family and is scheduled to lapse in the last week of February 2027. Both serve air‑distribution applications where specifiers often ask for current product‑specific EPDs.

Are replacements already live

We do not see newer, like‑for‑like replacements posted in public operator libraries for these two exact SKUs as of today. ISOVER has, however, refreshed adjacent SKUs in the CLIMAVER range with current EPDs that run well beyond 2027, including entries for CLIMAVER A2 NETO and CLIMAVER Plus R, and regional issues such as KIMMCO‑ISOVER’s combined CLIMAVER Plus R U and CLIMAVER Neto U valid through late 2029 (EPD International, 2025). That helps for nearby specifications, but it is not a one‑to‑one swap if a tender names the expiring product.

What specifiers will likely do if no update lands

In duct systems, teams reach for in‑date declarations to avoid documentation gaps. Expect three brands to surface fast in substitution conversations:

• Kingspan KoolDuct phenolic duct system, valid to 2029‑12‑12 in EPD International, commonly positioned as a lightweight ductwork alternative (EPD International, 2025).
• ROCKWOOL Conlit Duct 120 within a high‑density stone‑wool EPD family that is valid to 2031‑01‑22 in Europe, covering fire‑resistant duct insulation needs (EPD International, 2026).
• URSA AIR duct panels, with a current EPD to 2027‑12‑20 that keeps them eligible on documentation‑driven projects (EPD International, 2026).

These are not endorsements. They are the obvious shelves others will pull from when an EPD date tips over. That is how specs really move in practice.

Commercial risk in one picture

Think of a jobsite submittal like airport security. A current EPD is the boarding pass. It barely gets noticed when it scans green, but one red blink can send the whole team back to the ticket counter. When a declaration is weeks from expiry, project managers start planning alternates. If it actually expires, the swap often happens without debate.

Renewal timing and PCR context

EPDs typically run on a five‑year validity. Renewals may also pull in updated PCR rules, which can shift impact reporting or modules. That is normal. The key is timing. Aim to have the successor declaration live a few weeks before the posted end date so channel partners never feel the wobble. If in‑house bandwidth is tight, prioritise the highest‑revenue SKUs first, not the easiest datasets.

What to do this week

• Confirm scope: lock the exact SKUs that need a like‑for‑like successor rather than relying on adjacent CLIMAVER entries.
• Align operator: keep to the operator and standard your buyers already accept for duct systems unless there is a strategic reason to move.
• Pre‑brief sales and distribution: share the planned publication window so they can hold the line on specs. One clear slide beats ten follow‑up emails.

Where to find current ISOVER EPD listings

ISOVER publishes EPD and FDES resources across its regional sites. Useful starting points include ISOVER UK’s EPD certificates hub and ISOVER Italy’s EPD library. Selected product FDES pages in France, such as Vario Xtra Band and the Vario Xtra membrane, also surface document links buyers ask for.

• ISOVER France product pages with FDES: Vario Xtra Band and Membrane Vario Xtra

For broader category background, our recent manufacturer brief on ISOVER’s portfolio and EPD coverage maps the range and main operators, and this URSA expiry watch shows how quickly share can drift when a window is missed.

Bottom line for spec‑driven sales

Two HVAC duct system EPDs in the ISOVER catalog hit their finish line in February 2027. We do not see published one‑to‑one successors yet, and competitors already have valid declarations in market. Keep the ductwork story simple for buyers. Ship the renewal on time so a strong position in mechanical packages does not get traded away for a paperwork miss. That would be a silly unforced error, and easily avoidable.
