Reynaers Aluminium: EPD coverage at a glance
Reynaers Aluminium is a full‑system player in architectural glazing. Windows, doors, sliders, façades, even shading. The portfolio spans many product families and likely hundreds of SKUs, yet their public EPD footprint feels uneven. They state 19 generic EPDs that cover 67 product variants, which is helpful, but specifiers often look for product‑specific EPDs tied to exact systems, especially as LEED v5 tightens expectations for transparency (Reynaers Aluminium, 2025).
Who Reynaers is and what they sell
Reynaers Aluminium is a Belgium based systems house focused on aluminium windows, doors, sliding and folding systems, curtain walls, skylights, and solar shading. Think MasterLine, ConceptSystem, ConceptPatio, Hi‑Finity, ConceptWall, and ElementFaçade families. The range targets residential and commercial projects from multifamily to hospitals and education.
The catalogue is broad. Across regions and variants, we see multiple design and insulation options per family, easily into the hundreds of SKUs. That depth helps architects fine tune performance without changing visual language.
EPD footprint today
Reynaers’ own sustainability pages state they offer 19 generic EPDs that cover 67 product variants, with downloads available from product pages and regional portals (Reynaers Aluminium, 2025). Generic here means one declaration can represent several closely related variants within a family. That can be a good first step during a rollout.
Publicly findable, product‑specific EPDs by named system appear limited right now. A number of historical declarations for sliding doors, windows, and curtain wall families are visible in archives, yet several seem to have lapsed in recent years. Renewal cadence matters because project teams and third‑party reviewers check validity windows quickly.
What this means in the spec room
On projects chasing carbon targets or LEED v5 points, a family‑level or generic EPD may not unlock the same credit path as a product‑specific Type III EPD that names the exact system. When that happens, teams often default to conservative carbon factors which can disadvantage products in close bids. In practice, that means more price pressure and fewer easy wins.
Likely gaps to watch
Curtain wall systems are frequent headline items on complex jobs. If a designer cannot match a planned Reynaers façade family with a current, product‑specific EPD, they may pivot to a like‑for‑like with an active declaration from another brand. Sliding door systems are similar in high‑rise residential where balcony doors are repeated by the hundreds per tower.
Competitors that often show up on the same drawings
Common alternatives include Schüco, Kawneer, YKK AP, and AluK. Each competes across windows, doors, storefront or unitized and stick façades. Several publish current, product‑specific EPDs across multiple categories through well known program operators such as UL, IBU, and EPD International. YKK AP states it provides third‑party certified EPDs across seven façade categories for all products produced in its Georgia facility, which signals breadth buyers can verify quickly (YKK AP, 2025). Kawneer maintains a broad UL‑certified set that covers major storefront and curtain wall families, which specifiers can download from their transparency pages (Kawneer, 2025).
Where Reynaers is already strong
Breadth of systems and aesthetics is a real asset. MasterLine windows and doors, plus elements like SlimLine and Hi‑Finity, give designers a consistent design language across openings. When a product‑specific EPD exists for a flagship family and is easy to find on the product page, it tends to travel fast across specs. That speed matters when submittals stack up.
How to close the gap quickly
If coverage is patchy, start with the highest‑run families in windows, curtain wall, and sliding doors. Publish product‑specific EPDs that name the exact system and typical configurations, then cascade to other variants. Pick the same PCRs competitors use so credits and comparisons line up cleanly. Keep renewal dates on a shared calendar with sales so no one is surprised mid‑bid.
A practical tip we see work again and again. Make data collection painless for plant and product teams. Centralize utility, scrap, alloy, and packaging data by reference year, then let an experienced LCA partner do the heavy lifting of modeling, operator selection, and verification. That approach compresses timelines and frees engineers to build better product, not spreadsheets.
Where to find Reynaers’ sustainability information
For those digging deeper, Reynaers hosts EPD and certification information alongside product downloads. Their sustainability hub is a good starting point for current statements and links to documentation. See Certified and Traceable Information on their site (Reynaers Aluminium, 2025).
The commercial readout
Aluminium systems often decide a project’s carbon math. Showing up with product‑specific, current EPDs turns that math into a feature instead of a hurdle. It reduces substitution risk, shortens back‑and‑forth in reviews, and wins tie‑breakers where everything else is equal. If there is one place to invest next quarter, prioritizing the curtain wall and sliding families is a safe, high‑leverage bet. It’s definately the kind of move that pays for itself with a single mid‑size project win.
Frequently Asked Questions
What products does Reynaers Aluminium compete with most often on commercial projects?
Windows, doors, sliding or folding systems, and curtain wall façades. These appear frequently in offices, multifamily, healthcare, education, and mixed‑use. Competitors often include Schüco, Kawneer, YKK AP, and AluK.
Does a family‑level or generic EPD always satisfy project requirements?
Not always. Many design teams and LEED v5 pathways prefer product‑specific Type III EPDs that name the exact system. Generic or family EPDs can be a temporary bridge, but they may not carry the same credit value.
If we start an EPD program now, which Reynaers families should be first?
Prioritize the highest‑volume curtain wall, sliding door, and flagship window families. Those drive most of the embodied‑carbon and specification decisions on complex jobs, so EPDs there unlock the most revenue.
What slows EPD timelines inside manufacturers?
Data wrangling across plants and ERP systems. The fastest programs streamline collection for a single reference year, align on a common PCR, and let a specialized LCA partner run modeling and program‑operator coordination.
