MM Holz: product lines and EPD coverage today
Mayr‑Melnhof Holz sits in Europe’s first row for mass timber. Their catalog spans structural CLT to glulam systems and workhorse formwork components. Here’s the quick read on what they sell, how broad the range is, and where Environmental Product Declarations already support specification versus where a new EPD could unlock more bids.
Who MM Holz is
Mayr‑Melnhof Holz is a long‑standing timber group with mills and engineered‑wood plants across Austria, Germany, Czechia and Sweden. They market structural solutions under clear product brands and supply both commodity sawn timber and project‑specific elements that arrive CNC‑ready for site.
What they sell, at a glance
Their portfolio covers several structural families, plus adjacent lines:
- Cross‑laminated timber panels branded MM crosslam for walls, floors and roofs.
- Glued laminated timber beams branded MM masterline, including engineered and curved members.
- Duo and trio beams (MM vistaline) for frames and roof structures.
- Glulam floor and wall beams (MM blockdeck) and glulam ceiling elements (MM profideck).
- Glulam house building elements (MM HBE) and timber engineering services.
- Formwork beams and 3‑ply formwork panels for concrete trades.
- Sawn timber and pellets from integrated sawmills.
Across formats, grades and dimensions, the SKU count comfortably sits in the hundreds. That breadth means specifiers can often source an entire superstructure from one catalog.
Current EPD coverage
Two pillars are already covered by manufacturer‑specific, third‑party declarations.
CLT. In April 2024, MM crosslam received a product‑specific EPD under EN 15804+A2, published by IBU with declaration number EPD‑MAY‑20240070‑IBA1‑DE (IBU, 2024) (IBU, 2024).
Glulam. In July 2025, glulam EPDs for multiple plants were posted in the International EPD System with validity to July 7, 2030. Examples include Wismar and Olsberg in Germany, and Reuthe in Austria, all referencing EN 15804+A2 (International EPD System, 2025) (EPD‑IES‑0004617, 2025, EPD‑IES‑0004675, 2025, EPD‑IES‑0004747, 2025).
Likely gaps to close
We did not find public, product‑specific EPDs for MM HBE elements, MM profideck or blockdeck components, nor for the formwork panel and beam range as of December 20, 2025. If these lines are strategic volume drivers, publishing EPDs could remove friction on public tenders and owner programs that now prefer product‑specific declarations, especially during the market’s move into LEED v5 materials pathways (USGBC, 2025) (USGBC, 2025).
Why it matters commercially
On LEED projects still using v4.1 during the transition, a product‑specific Type III EPD with external verification counts more in the tally than a generic document. Teams often need at least 20 qualifying products with extra weight for product‑specific EPDs, so a well‑covered catalog makes you easier to specify and reduces substitution risk in late‑stage reviews (USGBC Credit Library, 2024).
Competitors you’ll meet in the spec
For CLT and glulam superstructures, MM Holz most often competes with European heavyweights like Stora Enso, Binderholz, KLH, HASSLACHER, X‑Lam Dolomiti, plus regional players in North America on certain jobs. Many already maintain active EPDs across core lines, for example Stora Enso’s CLT and rib panels in the International EPD System that remain valid through 2028, which can influence shortlist decisions on projects chasing materials points (International EPD System, 2023). A ribbed CLT slab can be evaluated against glulam floor systems in education or office spans, so having an EPD for MM profideck would help keep parity on EPD‑screened tenders (EPD‑IES‑0009949, 2023; EPD‑IES‑0009950, 2023).
Where MM Holz publishes sustainability proofs
The company’s download hub centralizes plant certificates and product attestations, useful for submittals and prequalification. It is worth bookmarking the Certificates section for updates, since new EPDs often appear there first before case studies filter in (Certificates, 2025).
Practical next steps for product managers
If you manage MM‑like portfolios, pick the EPD sequencing by commercial impact. Start with high‑volume engineered elements that hit multiple building types, then expand to system components that unlock full‑catalog wins. A strong LCA partner will map the dominant PCR choices for your segment, align the operator to your markets of sale, and run a data collection that feels like a guided intake rather than a spreadsheet marathon. That is how teams protect timelines and get credible declarations out the door quickly. It’s not about publishing every possible document, it’s about covering the few prdoucts that move most revenue.
The bottom line
MM Holz already checks the biggest box with product‑specific EPDs for CLT and glulam. The opportunity lies in extending coverage to prefabricated glulam elements and formwork lines where specifiers increasingly expect an EPD as table stakes. Close that gap and the catalog competes on design, lead time and value, not on documentation preferrence alone.
Frequently Asked Questions
Does MM Holz have a product-specific EPD for cross-laminated timber?
Yes. IBU published a manufacturer-specific EPD for MM crosslam in April 2024 under EN 15804+A2, declaration EPD‑MAY‑20240070‑IBA1‑DE (IBU, 2024).
Are there current EPDs for MM Holz glulam beams?
Yes. Glulam EPDs for Wismar, Olsberg, and Reuthe plants were posted July 8, 2025 in the International EPD System, valid until July 7, 2030 (International EPD System, 2025).
Which MM Holz product families likely still lack public EPDs?
As of Dec 20, 2025, we did not find product‑specific EPDs for MM HBE, profideck, blockdeck, or the formwork beams and panels on public registers. Prioritize these if they drive bids.
Which competitors commonly show up with EPDs on similar scopes?
Stora Enso, Binderholz, KLH, HASSLACHER, and X‑Lam Dolomiti, among others. Several maintain valid EPDs for CLT or glulam that can sway EPD‑screened tenders (International EPD System, 2023–2025).
Where can I find MM Holz sustainability and certificate documents?
Use their Certificates hub for plant‑level attestations and product documents, including updates to EPDs and technical sheets.
