Congratulations, TimberHP. First EPD unlocked.
A newcomer just put numbers behind the wood fiber story. TimberHP’s first environmental product declaration lands in January 2026 for its flagship batt insulation, a signal to specifiers that this category is ready for prime time. Here is what they published, who verified it, and how the move reshapes the competitive map for thermal and acoustic insulation in North America.
Who TimberHP is and why this matters now
TimberHP manufactures wood fiber insulation in Madison, Maine for residential, multifamily, and light commercial projects. Their portfolio spans cavity batts, dense‑pack loose fill, and exterior boards that promise comfort, acoustics, and vapor‑open assemblies many builders want today. A verified EPD takes that promise from marketing to math, which is what carbon‑accounted projects look for.
What TimberHP just published
TimberHP has released a product‑specific EPD for TimberBatt High‑Performance Thermal and Acoustic Cavity Batt Insulation. It is issued by EPD Hub and pubished in January 2026, with validity running into 2031. The declaration references the Building Envelope Thermal Insulation Part B rule set and identifies TimberHP as the LCA developer, which signals in‑house ownership of data and model quality.
Scope notes at a glance
This is a single‑manufacturer, product‑specific declaration that covers the TimberBatt line rather than a generic industry average. The EPD addresses thermal and acoustic batt use in framed cavities, which is where most day‑to‑day spec decisions happen for walls, floors, and roof rafter bays. In other words, it lands exactly where submittals tend to stall without verified numbers.
Competitive lens (who else is visible in specs)
Owens Corning maintains numerous current EPDs for blanket and board insulation across North America, typically published through SCS Global Services. That means they enter most bids with ready documentation for cavity insulation.
CertainTeed Saint‑Gobain likewise shows multiple current EPDs for blanket, blown, and board formats, commonly issued by Smart EPD. They are well covered on the core formats that go head‑to‑head with batts.
GUTEX, a close peer in wood fiber, does not show a current thermal‑insulation EPD in the common North American portals we reviewed as of this week. That gap gives TimberHP a near‑term edge when teams want wood fiber batts with product‑specific declarations for submittals.
What this unlocks in real bids
A product‑specific EPD reduces friction in owner and A/E reviews because it replaces pessimistic default factors with verified values. It also enables credit pathways in programs that prize product‑level transparency, including LEED v5 draft language for envelopes. The punchline is simple. A credible EPD helps keep TimberBatt in the mix on projects that track embodied carbon and prefer product‑specific declarations instead of generic averages.
Timing and program operator
The EPD arrives in January 2026 and is issued by EPD Hub, a recognized program operator that publishes declarations under ISO 14025 and EN 15804 frameworks. That pairing gives procurement teams confidence that the format and verification meet current expectations for comparative use and reporting.
What to watch next
If TimberBoard and TimberFill follow with product‑specific EPDs, TimberHP will have coverage across cavity, dense‑pack, and continuous exterior insulation. That would match how designers actually assemble high‑performance envelopes and it would make the spec conversation feel like picking tracks on a great playlist instead of hunting across labels.
Website visibility check
We did not see the EPD linked on TimberHP’s product or resource pages at the time of writing. Visibility is key, so the fastest win is to add the EPD to the TimberBatt page and the Technical Resource Library, then cross‑link it from the 3‑part spec and ICC‑ES materials so submittal packages assemble in one click.
Takeaway for manufacturers
This is what entering the transparency arena looks like. Publish where your buyers make decisions, cover the product families that drive most line items first, and keep your data collection ruthlessly organized so renewals are painless. Teams that streamline the internal data wrangle tend to move faster and spend more time on product and plant improvements rather than paperwork.
Image idea: celebratory confetti over a neat stack of wood fiber batts on a clean jobsite, bright natural light, optimistic color palette.
Frequently Asked Questions
Which product did TimberHP cover with its first EPD and who issued it?
TimberHP’s first declaration covers TimberBatt High‑Performance Thermal and Acoustic Cavity Batt Insulation. It is issued by EPD Hub and identifies TimberHP as the LCA developer, with validity into 2031.
Does this EPD cover a single SKU or a product family?
It is product‑specific to the TimberBatt line, which typically includes multiple thicknesses and sizes used in framed wall, floor, and roof cavities.
How does TimberHP’s coverage compare to major batt competitors?
Owens Corning and CertainTeed both have multiple current EPDs for batt and board formats. Among wood fiber peers, GUTEX does not show a current thermal‑insulation EPD in North American portals as of this week, which gives TimberHP an edge for wood fiber batts.
What should happen on the website after an EPD is published?
Post the PDF in the product page downloads and the technical library, reference it in the 3‑part spec and ICC‑ES report, and make it easy to find from search.
