Eight Celotex Saint‑Gobain insulation EPDs are slated to lapse in February 2027. For bid teams, the headline is better than it sounds. Isover UK, part of the same group, has already published fresh EN 15804+A2 EPDs for the same product lines with validity into 2030, so specability stays intact. Below we map what’s expiring, where the new documents live, and which competitors have current EPDs if a niche thickness or variant still needs a backup.

What’s scheduled to lapse in February 2027

Celotex Saint‑Gobain’s EC3 listing shows eight thermal and acoustic glass mineral wool EPDs set to expire in February 2027. The affected lines are familiar UK staples used in partitions, lofts, cavities, and HVAC wraps. Think of this as a TV season finale, not a series finale.

Impacted product EPDs

  • Climcover Roll Alu2 25 mm, 40 mm, 50 mm (duct and HVAC wrap)
  • Acoustic Partition Roll APR 1200 25 mm; 50 mm and 65 mm; 75 mm and 100 mm (internal partitions and floors)
  • Spacesaver and Spacesaver Ready‑Cut product family (lofts and joists)
  • Cavity Wall Slab CWS 32 65–100 mm (masonry cavities)

The update: replacements are already live to 2030

Isover UK has published new, product‑specific Type III EPDs for these same lines in The International EPD System. Examples include Climcover Roll Alu2 25 mm, valid until 2030‑04‑21 (EPD International, 2025); APR 1200 25 mm, valid until 2030‑04‑21 (EPD International, 2025); and Cavity Wall Slab 32 75 mm, valid until 2030‑05‑21 (EPD International, 2025).

Product‑by‑product snapshot

Here is how the 2027 expiries line up against fresh certificates now available from Isover UK. Where the older EPD covered multiple thicknesses in one document, the refresh splits them into single‑thickness EPDs.

  • Climcover Roll Alu2 25/40/50 mm → new single‑thickness EPDs valid to 2030‑04‑21. See the Climcover product page for 25/40/50 mm EPD PDFs (Isover UK site, 2026).
  • APR 1200 25/50/65/75/100 mm → new single‑thickness EPDs valid to 2030‑04‑21. The 50 and 65 mm files are posted, with 75 and 100 mm likewise live on Isover’s documents hub (Isover UK site, 2026).
  • Spacesaver and Spacesaver Ready‑Cut → new EPDs at 100, 150, and 200 mm, valid to 2030‑04‑21 (Isover UK site, 2026).
  • Cavity Wall Slab CWS 32 65–100 mm → new single‑thickness EPDs, for example 75 mm valid to 2030‑05‑21. Additional thicknesses follow the same pattern (EPD International, 2025).

Useful links for submittals

Will specifiers lose access to EPD data?

Unlikely. With the 2025 Isover UK EPDs in place, the lines above remain covered through 2030 for EN 15804+A2 scopes. The paperwork is simply moving from older, family‑style records to single‑product EPDs that are cleaner to cite in LEED v5 submittals. Dont leave outdated PDFs in your template library though.

If a gap appears, credible alternatives exist

If a specific thickness goes out of stock or an unusual variant lacks a posted PDF for a week, specifiers typically pivot inside the same performance class.

  • HVAC duct and wrap insulation: Knauf Insulation Thermo‑teK LM Eco ALU carries a current product‑specific EPD valid to 2029‑05‑16 (EPD International, 2024).
  • Internal partitions and general building insulation: ROCKWOOL stone wool ranges for the Saint‑Eloy site hold EPDs valid to 2028‑11‑17, widely used across walls and façades (EPD International, 2023).
  • HVAC duct wrap alternative: URSA AIR Manta aluminio reinforced variants are covered to 2028‑06‑11, a common substitute for foil‑faced rolls in duct applications (EPD International, 2023).

Why this timing matters for commercial teams

Most construction teams only check EPD freshness when a submittal hits QA. That is late. A tidy set of live, product‑specific EPDs shortens back‑and‑forth with GC sustainability teams and avoids being swapped for a rival that can be counted in project carbon models. The refreshed documents also align with current c‑PCRs for thermal insulation under EN 16783, which improves comparability for buyers.

The practical play

Update specification notes, model libraries, and sales collateral to point at the Isover UK EPDs noted above. Keep a light watch on your calender for 2030 renewals. If a one‑off thickness is missing online, grab a near‑neighbor thickness EPD in the same family while you request the exact file from the manufacturer. That keeps submittals moving without drama.

Frequently Asked Questions

Do specifiers need to change the manufacturer name in submittals from Celotex Saint‑Gobain to Isover UK?

Yes. The current EPD owners list Saint‑Gobain ISOVER UK Ltd, so update submittals to reference that entity and the new EPD registration numbers.

Are the new EPDs based on EN 15804+A2 and valid for LEED v5 documentation?

Yes. The replacements are registered in The International EPD System under EN 15804+A2. They are suitable as product‑specific Type III EPDs in LEED v5 materials accounting.

Do the new single‑thickness EPDs replace older multi‑thickness family EPDs?

In practice, yes. The refresh shifts from multi‑thickness family records to individual thickness EPDs. Use the exact thickness file when available, or the closest thickness in the same family if timing requires.

Where can I download the updated documents quickly?

Use Isover UK’s EPD certificates page for direct PDF downloads: https://www.isover.co.uk/technical-services/resources/epd-certificates. Key products also host EPD links on their product pages.
