What’s expiring in December 2026
Two glass wool insulation declarations for Saint-Gobain Denmark AS are scheduled to expire on December 8, 2026. The expiring products are ISOVER CLIMCOVER Slab (MasterFormat 07 21 16 Blanket Insulation) and ISOVER Granulat, a loose‑fill glass wool used for blown applications (MasterFormat 07 21 00 Thermal Insulation). Both are published in the Nordic market under EPD Norway and reference thermal insulation Part B rules.
Are replacements already in place
As of April 20, 2026, no new or successor EPDs for these exact ISOVER products are visible. Many Weber mortars and grouts from the same legal entity remain current through 2027 to 2029, but that does not cover these two insulation SKUs. If nothing changes, specifiers using these exact lines will see a data gap after December 8, 2026.
What specifiers will reach for instead
When an insulation EPD lapses, project teams dont wait around. They switch to comparable products with live declarations.
- Knauf Insulation glass wool blanket lines such as CLASSIC 037, NATUROLL 037, and UNIFIT 037 hold current EPDs with validity into March 2029 through EPD International AB, covering internal partition and facade blanket uses.
- URSA PURE FLOC and related blown glass wool families carry active EPDs through March 2028 under EPD International AB, a direct alternative to loose‑fill applications like Granulat.
- ROCKWOOL stone wool building insulation is listed with validity to February 2030 via EPD International AB, giving specifiers a mineral wool route across common wall and roof assemblies.
Will EPD data access be lost
For these two SKUs, yes after December 8, 2026 unless renewals land. Projects that require a product‑specific, third‑party verified EPD will typically favor products that keep their declarations current. That changes the short list in pre‑bid, then again at final submittal when documentation is checked.
Renewal timing that works
Most operators set EPD validity at five years, so planning a refresh on a 48 to 54 month cadence avoids last‑minute sprints and keeps specs safe while PCRs evolve (EPD International GPI, 2025). Start data collection now for a Q4 publication window. That buffer protects against verification queue time and any bill‑of‑materials or energy dataset updates uncovered during LCA.
Where to follow updates
Manufacturer product and sustainability information is centralized on Weber Denmark’s site. See their home hub for product lines and documentation updates at https://www.weber.dk. For a broader scan of insulation EPDs, check the program operator listings for EPD Norway and EPD International AB.
Why this matters commercially
A current EPD keeps a product on the shortlist without price becoming the only lever. Letting a declaration lapse invites a quiet substitution toward brands with live, verified data. Renewal on time preserves spec eligibility and saves sales teams from fighting uphill in late‑stage documentation checks.
