Knauf Insulation SAS: 26 FDES expire March 2027

What is set to expire in March 2027

We identified a pack of glass mineral wool FDES dated 2022‑03‑15 that end 2027‑03‑15 in MasterFormat 07 21 16 Blanket Insulation. Representative SKUs include:

• Laine de Verre ECOSE KI FIT 035 280 mm
• Laine de Verre ECOSE KI FIT 035 240 mm
• Laine de Verre ECOSE KI FIT 037 370 mm
• Laine de Verre ECOSE KI FIT 032 200 mm
• Laine de Verre ECOSE KI FIT 040 240 mm
• Laine de Verre ECOSE RT PLUS 035 280 mm
• Laine de Verre ECOSE RT PLUS 035 220 mm
• Laine de Verre ECOSE TI 212 280 mm
• Laine de verre à souffler Supafil Loft 045
• Laine de verre à souffler Thermo Loft

These cover common thicknesses for roof spaces and framed walls. A further sixteen March‑2027 expiries sit in the broader 07 21 00 Thermal Insulation family. Names repeat by thickness and facing, so the business risk is real even if individual SKUs feel niche in isolation.

Are replacements already live

Yes in many cases. Knauf Insulation SAS has newer A2 FDES on the books that run to late 2028 or mid‑2029 across the same families. Examples include TI 212 at 80, 100, 120, 160, 200, 240, 260, 300 and 320 mm valid through 2028‑03‑17, plus RT PLUS 032 variants at 60, 120 and 140 mm on the same 2028‑03‑17 horizon. A 2024‑07‑05 set covers systemized “Système RT PLUS Murs” assemblies through 2029‑07‑05, and fresh Acoustilaine/Naturoll entries reach 2029‑07‑05. That pattern suggests an ongoing migration from older A1 records to A2.

Where a gap may remain

We did not find direct A2 successors for a handful of very thick KI FIT and RT PLUS 035 SKUs that end 2027‑03‑15. Given the density of adjacent thicknesses already renewed, these may be next in the queue. Until a like‑for‑like appears, those exact SKUs could fall out of spec eligibility where project teams require an in‑force, product‑specific declaration. In France, most FDES refresh on a five‑year cycle, so timing your update window matters more than the model year on the packaging (INIES, 2025).

What specifiers might pick instead if a lapse occurs

Competitors with current declarations cover the same use‑cases and R‑value ranges.

• Rockwool France lists blown stone wool for attics such as ROCKPRIME 2 and JETROCK 2 with FDES valid to 2029‑07‑25 and 2029‑05‑10. These map neatly to Supafil or Thermo Loft applications (INIES, 2024).
• Isover has long‑running FDES for blown glass wool such as Comblissimo 465 mm valid to 2029‑06‑17, plus batts like Isoconfort 35 to 2028‑08‑23 that compete with KI FIT thicknesses (INIES, 2024).
• URSA publishes A2 EPDs for glass wool panels and XPS that stay live through mid‑2028, suitable alternatives where a specific KI FIT or RT PLUS thickness lapses (EPD International, 2023).

When FDES coverage slips, project teams often default to competitors with a current, product‑specific declaration. That is not a scare tactic, it is how carbon accounting and LEED v5 procurement work in practice.

Business impact for manufacturers

Specs are momentum games. Lose the EPD this quarter, and the next two quarters feel it. Sales teams then lean on price rather than performance to stay in the conversation. Keeping product‑specific EPDs current preserves access to tenders that would otherwise force generic or penalized values in the model, which is a tough handicap to race with.

Operator and registry context

Most of Knauf Insulation SAS’ French records are FDES listed with INIES under EN 15804 +A2 today. That is commercially helpful because many public and private clients in France check INIES first. Internationally, ENVIRONDEC remains a common operator for glass and stone wool where cross‑border marketing is in play. Public operator registries document validity windows and version shifts, so they are a simple place to verify coverage before a bid. See INIES and ENVIRONDEC for current practices and term structures (INIES, 2025; EPD International, 2025).

Renewal timing, simplified

Think of the five‑year term as a timer on the box. Start work nine to twelve months before expiry if you want zero‑drama continuity. That window leaves space to lock reference data, align on PCR choices your competitors already use, and consolidate thickness variants into fewer, clearer declarations. A clean SKU hierarchy also prevents “near miss” confusion when a buyer wonders whether a 200 mm FDES covers 180 mm in the submittal set.

A practical playbook to stay ahead

• Prioritize the March‑2027 list above, plus sister SKUs in 07 21 00, for fast‑track renewal. Bundle by family to reduce review churn.
• Mirror the PCR and operator routes your target competitors use in each market so comparisons land apples‑to‑apples. This is basic, still often missed.
• Align plants, utilities, and scrap assumptions early. The hardest work is data completeness inside the factory, not the math outside it.
• Publish before the last month. A quiet four‑week buffer has saved more bids than any brochure ever printed. Dont leave it to chance.

Closing thought

Knauf Insulation SAS appears to be deep into its A2 refresh, which is good news. Close the remaining March‑2027 items, especially the thick KI FIT and RT PLUS 035 variants, and the portfolio stays fully spec‑ready. Let the clock drift and buyers will reach for whatever has a green light in the registry. That choice is predictable, and preventable.
