Renson: product lines and EPD coverage at a glance

Who Renson is and what they sell

Belgium‑born Renson designs for “creating healthy spaces,” with solutions that manage air, sun, and outdoor living. Their portfolio covers mechanical ventilation systems and window vents, exterior solar shading and screens, continuous louvre façades, luxury pergolas, and accessories like CO₂ monitors and fans. In practice, they show up in homes, offices, healthcare, education, and data‑center façades.

How broad is the catalog

Across the core families, Renson serves five major product categories with variants in the hundreds. Think multiple ventilation units and window vent sizes, dozens of louvre profiles, several shading systems, and a full pergola line with configurable modules. The breadth is a commercial asset, but it also multiplies the EPD to‑do list.

What EPDs exist today

Two clear signals are public. First, Renson announced a validated FDES for its Linius continuous louvre façade system published in France’s INIES database, aligned to EN 15804+A2. That puts a flagship façade solution on the map for RE2020 projects. Second, the company points to a collective, association EPD for vertical blinds through Germany’s IVRSA, which indicates sector‑average coverage for certain solar shading use cases hosted by IBU.

For context, INIES remains the reference channel for construction products in France and has grown materially in 2025, listing 5,456 FDES and 1,791 PEP on December 14, 2025, representing 319,593 referenced items (INIES, 2025).

Where coverage looks thin

Ventilation hardware, fans, and several window‑vent families do not yet show product‑specific EPDs publicly. The pergola range also appears uncovered. Solar shading is only partially addressed via an industry‑wide declaration rather than Renson‑specific documents. That mix can work in some markets, but it leaves specifiers without brand‑level numbers when projects ask for product‑specific data.

Why that matters in bid rooms

When a team models whole‑building carbon, missing product‑specific EPDs trigger generic or pessimistic defaults. The result is avoidable penalties that push buyers toward brands with verified numbers, especially under LEED v5 workflows and European public tenders. INIES and operator sites are the playing field, not brochures. Publishing Renson‑specific EPDs for the top movers neutralizes that disadvantage.

A concrete risk moment: ventilation components

Competitors have started publishing EPDs for bathroom extract fans and in‑line duct fans under EN 15804+A2 with a ventilation‑components c‑PCR, so the category is ready. Two recent examples demonstrate market readiness and what spec teams will ask to see next year (EPD International, 2025 example 1, example 2). Eurovent also released recommendations to harmonize EPD rules for ventilation units in March 2025, which lowers ambiguity on scope choices for future declarations (Eurovent, 2025). If a project compares duct fans or central units side by side and only one bidder provides a verified dataset, guess who gets specified more often.

Competitors Renson typically meets on projects

For solar shading and architectural louvres, Hunter Douglas Architectural, Warema, Griesser, and Colt show up often. In ventilation, Zehnder, Swegon, Aldes, and Vent‑Axia are frequent alternatives, plus regional specialists like Duco for façade‑integrated solutions. For pergolas and outdoor structures, Corradi, Brustor, Azenco, and StruXure are common names. Several of these players already publish EPDs in at least parts of their range, which shapes spec shortlists even when performance is neck‑and‑neck.

Quick wins Renson could prioritize

Start where volume and substitution risk are highest.

• Ventilation components and window vents. Use the ventilation‑components c‑PCR family and align to the Eurovent guidance so data is comparable in Europe. Publish with IBU or the International EPD System and replicate on INIES when France matters.
• Solar shading. Keep the industry‑wide EPD for baselining, then add product‑specific EPDs for the top two shading systems to unlock stronger preference scoring.
• Pergolas. Treat the hero models as “systems” and scope the metal frame and integrated motors or lighting. One well‑scoped EPD covers a surprising number of configurations.

For teams juggling busy factories, the heavy lift is data wrangling. A white‑glove LCA partner that collects process data across plants, bills of materials, finishes, and supplier EPDs can compress months into weeks, without dragging R&D and operations away from launches. Done right, the first wave becomes a template library you can reuse instead of a one‑off.

Sustainability narrative link

Renson publicly frames its approach to responsible production and material choices here. It is worth aligning future declarations to the same narrative so the metrics and the message travel together in specs. See their sustainability page and charter for the official stance (Renson sustainability).

What we would watch next

Evidence of additional Renson EPDs landing on IBU, INIES, or Environdec in 2026, especially for ventilation units and leading pergolas. Expansion from association to product‑specific EPDs in solar shading. And a tighter internal bill‑of‑materials pipeline so finish and alloy choices are reflected in the numbers. Small changes there can move A1–A3 more than you’d expect. It’s a missed chance not to capitalize on that.
