REHAU: products and EPD coverage snapshot
REHAU is a polymer powerhouse across windows, piping, and interior surfaces. That breadth is an advantage when specs reward low‑carbon choices, yet it also creates complexity. Here is how their portfolio maps to Environmental Product Declarations today, where coverage shines, and where adding EPDs would unlock more bids in spec‑driven projects.
Who REHAU is in construction
REHAU spans three big arenas in the built environment: window and door profile systems, building technology piping and pre‑insulated networks, and interior surfaces with edgeband and storage components. The group reports more than 160 locations and roughly 13,000 employees globally, with several subgroups focused on building products (REHAU Group, 2025).
What they sell, at a glance
Across construction markets, REHAU offers PVC and RAU‑FIPRO window systems, PEXa plumbing and radiant lines such as RAUPEX and RAUTITAN, low‑noise drainage like RAUPIANO, pre‑insulated district heating pipes such as RAUVITHERM and RAUTHERMEX, and interior solutions under RAUKANTEX, RAUVISIO and RAUVOLET. By product family count they play in the dozens, and individual SKUs easily sit in the hundreds.
Where EPDs are already public
Interior Solutions is the brightest spot. REHAU states that official EPDs are available for its core interior product lines RAUKANTEX, RAUVISIO and RAUVOLET, verified by IBU and downloadable on their sustainability page (REHAU Interior Solutions sustainability, 2025). In windows, at least one product‑specific EPD is publicly listed for a SYNEGO window configuration with IBU as programme operator. Window Solutions also highlights circularity progress, noting its recycled content share exceeds the corporate average of 18 percent in 2024 reporting (REHAU Sustainability Report 2024, 2025).
Where coverage looks thin
As of December 2025, we could not locate public, product‑specific EPDs for flagship MEP and heat‑network lines like RAUPEX, RAUTITAN, RAUVITHERM or RAUTHERMEX on major operator libraries. That is a gap in North American healthcare, higher‑ed, and municipal work where specs or corporate policies prefer product‑specific EPDs under LEED v5‑aligned frameworks. In those cases, teams default to conservative carbon assumptions that can push a product out of contention on tight targets.
A likely bestseller without an EPD and what that costs
RAUPEX O2‑barrier PEXa pipe is a staple in radiant and plumbing catalogs. Without a published, third‑party verified EPD, specifiers comparing options for hospitals or schools can readily shift to peers that do carry one. Uponor and Wavin routinely publish product‑specific EPDs for PEX and pre‑insulated networks in European programmes, and Geberit lists multiple drainage system EPDs. That does not mean those products are lower carbon by default. It does mean they clear the administrative hurdle on day one, so they get short‑listed more often.
Competitors you will meet on bids
On PVC and composite window systems, expect VEKA, Deceuninck, GEALAN, aluplast, and Schüco. On plumbing, drainage, and district energy, the recurring set is Uponor, Wavin, Geberit, and GF Piping Systems. These are the names owners and GCs already know when the spec mentions product‑specific EPDs.
Quick wins to raise specability
- Prioritize EPDs for RAUPEX and RAUTITAN first, covering mainstream diameters and fittings so estimators can document entire assemblies. 2) Add pre‑insulated Eco‑equivalents like RAUVITHERM and RAUTHERMEX, since campus and district jobs often evaluate those lines together. 3) Mirror the PCR choices common among the competitors above so your results are comparable in submittals. A capable LCA partner will investigate the prevailing PCRs, operator options, and expiry timing, then shoulder the data collection across plants and SKUs so your team doesnt stall.
Why this is worth it commercially
Most project teams do not scrutinize the vintage of an EPD as long as it is valid, but they do penalize the absence of one in their carbon accounting. Publishing a product‑specific, third‑party verified EPD removes that friction so sales teams spend less time arguing assumptions and more time winning scope. The lift to gather utility, materials, and yield data is real, which is why picking a partner who makes internal data pulls painless is the difference between a six‑month slog and a quick, clean publication.
Sustainability resources
If you want the bigger picture on REHAU’s sustainability posture, their group page centralizes policies and reports and links to the 2024 report download (REHAU Group sustainability, 2025). That report notes Window Solutions’ recycled content performance vs the corporate average of 18 percent (REHAU Sustainability Report 2024, 2025).
Bottom line for spec‑driven work
REHAU’s interior portfolio is EPD‑ready, windows have a starting foothold, and building‑tech piping is the open field. Publishing EPDs for PEX plumbing, drainage, and pre‑insulated networks would close the most material revenue gap in LEED v5‑oriented and policy‑driven jobs, ensuring their systems are evaluated on performance, not on paperwork.

Frequently Asked Questions
What parts of REHAU’s portfolio already have public EPDs?
Interior Solutions reports EPDs for RAUKANTEX edgebands, RAUVISIO surfaces, and RAUVOLET roller shutters, verified by IBU and linked on their sustainability page (REHAU Interior Solutions sustainability, 2025).
Is there a product‑specific EPD for REHAU windows?
At least one SYNEGO window configuration is listed with IBU as programme operator. Window Solutions also reports recycled content performance above the corporate average of 18 percent in 2024 reporting (REHAU Sustainability Report 2024, 2025).
Where are the main EPD gaps for REHAU today?
As of December 2025, we did not find public product‑specific EPDs for RAUPEX and RAUTITAN plumbing, RAUPIANO drainage, or RAUVITHERM and RAUTHERMEX pre‑insulated pipes on major libraries. These lines are high‑impact for LEED v5‑leaning specs.
