What is expiring in January 2027
As of May 20, 2026, seven Johns Manville fiberglass batts EPDs show a validity window ending on 2027‑01‑01. They sit under Building Envelope Thermal Insulation and were issued in January 2022 by UL, with a five‑year validity noted in the PDF (UL, 2022).
The expiring EPDs cover these scopes and product families:
- Fiberglass Batts and Rolls (company‑specific family EPD)
- Fiberglass batts (faced) — McPherson plant
- Fiberglass batts (faced) — Penbryn plant
- Fiberglass batts (unfaced) — McPherson plant
- Fiberglass batts (faced) — multi‑plant
- Fiberglass batts (unfaced) — multi‑plant
- Formaldehyde‑free Fiber Glass Insulation (family EPD)
Think of these as the mainline cavity insulation workhorses. When their declarations lapse, carbon accounting on batts gets harder for design teams.
Are replacements already live
We could not find newer JM batts EPDs with later validity dates. The 2022 batts PDF remains the current reference and shows the five‑year clock running through January 1, 2027 (UL, 2022). If a refreshed EPD is in motion, it was not yet posted on JM’s EPD library at the time of writing.

What stays covered at JM
Coverage remains for other JM lines. Recent declarations are visible for blown‑in fiberglass families like Climate Pro and Spider Plus, mechanical insulation such as Micro‑Lok HP and duct wraps, mineral wool boards, and several roofing systems, all with validity past 2027 on JM’s site and program‑operator listings (JM EPD library pages accessed May 2026).
If batts are not renewed in time, where specs may pivot
Specifiers on projects that require product‑specific EPDs will look for functionally equivalent batts with current declarations:
- Owens Corning PINK Next Gen Fiberglas batts — EPD valid Sep 1, 2023 through Aug 31, 2028 (SCS Global Services, 2023).
- CertainTeed Saint‑Gobain Sustainable Insulation and Blanket Insulation — EPDs dated June and July 2024 with validity into 2029 (Smart EPD, 2024).
- Knauf Insulation EcoBatt batts and rolls — Sustainable Minds Transparency Report [EPD] published December 2023 with validity shown into 2028 on the program site (Sustainable Minds, 2023).
These are the like‑for‑like alternatives that keep EPD documentation clean while holding the line on thermal performance.
Commercial impact in plain terms
No current EPD on a core batt product means more friction to stay in spec when owners demand product‑specific declarations. Many project teams assign conservative carbon factors when an EPD is missing, which makes substitution more likely. That is avoidable with timely renewal and fast program‑operator publication.
Timelines that work in the real world
A practical play is to finalize updated batts data and verification early in Q4 2026, so the refreshed PDFs publish before 2027‑01. That gives distributors and bid teams a clean handoff. Aim for a public PDF at least 60 to 90 days before the old one lapses, so EC3, program libraries, and internal content hubs all reflect the change.
Where to verify status
Start with JM’s central EPD library for product‑family pages and PDFs: Environmental Product Declarations at Johns Manville (https://www.jm.com/en/environmental-product-declarations/). For a quick check on a specific batt SKU, the Building Insulation Fiberglass page is a good jumping‑off point (https://www.jm.com/en/environmental-product-declarations/Building-Insulation-Fiberglass/). Some legacy JM EPDs also appear on EPD Directory, which can be helpful for historical context (https://epd.directory/product-category-rules-pcrs/construction-products-and-construction-services-en-15804-a1/b65339d8b3a04d2eb422a2de51bb1781).

Bottom line
The risk is narrow and fixable. Seven JM batts EPDs are set to expire on 2027‑01‑01, and we did not find replacements posted yet. Competitor batts carry current EPDs into 2028 and 2029, so if renewal slips, projects will pivot. Publish early, keep the PDFs easy to find, and make the handoff boring. That is definitley the goal.
