What Silvadec does

Silvadec is a French manufacturer of wood composite products for outdoor construction, founded in 2001 and headquartered in Arzal, Brittany. Its core offering covers three application categories: terrace boards, fencing, and facade cladding, sold under the Atmosphère and Nuances coextruded ranges and the Élégance mono-extruded range, with an aluminum fencing line introduced more recently. The underlying technology combines approximately two-thirds PEFC-certified wood flour (sourced from France) with one-third polyethylene; premium products use a proprietary four-sided coextrusion process that wraps the composite core in a protective polymer shell, delivering UV stability, stain resistance, R13 slip resistance, and a 25-year residential warranty.

The company runs a hybrid B2B/B2C go-to-market anchored in wood-and-materials distributors (négoces) across more than ten European countries, supported by field sales representatives, a dedicated Pro Installer portal, and a prescriber channel offering CAD/BIM objects, FDES certificates, and CCTP documentation for architects. Revenue is generated through one-time product sales at unit prices of €101-125/m² for terrace boards, with complementary revenues from installation accessories, specialized cleaning products (Silvawash, Silvaction, Silvanet), and a new B2B stream of industrial recycled plastic granules from the Heuliad Environnement subsidiary launched in March 2025. Vertical integration is central to Silvadec's economics: the wholly-owned Silvadec Fibres unit (established 2014) supplies wood flour, while Heuliad Environnement closes the plastic loop and generates external B2B revenue.

Silvadec reported revenue of approximately €40M in 2024 with 110 employees, and claims European market leadership in wood composite for outdoor applications. The ownership remains concentrated with co-founders Bénédicte Jézéquel (CEO) and Philippe Crez; the company is privately held with no disclosed institutional investors. With a planned second manufacturing site in Bavaria, Germany, targeted for 2026, and a dense stack of certifications (EcoVadis Platinum top 1%, ISO 9001/14001/50001, PEFC, FDES, Origine France Garantie), Silvadec is positioning for further geographic expansion while deepening its circular-economy and prescriber-channel moats.

Core offering

Silvadec manufactures and sells wood composite exterior products across three application categories: composite terrace boards (Élégance, Atmosphère, Nuances ranges), composite and aluminum fencing, and composite facade cladding (Bardage Atmosphère 175 and claire-voie). The company also distributes specialized maintenance products (Silvawash, Silvaction, Silvanet) and operates self-service configurators for terraces, fences, and facades that route customers to its dealer network.

Product overview

Silvadec is a manufacturer of wood composite exterior products, operating as a single unified product portfolio divided into three core application categories: terrace boards (Terrasse), fencing (Clôture), and facade cladding (Façade). The product portfolio includes coextruded Atmosphère and Nuances ranges (premium), mono-extruded Élégance range (accessible), and an aluminum fencing line. Supporting the product lines are installation accessories, specialized cleaning products (Silvawash, Silvaction, Silvanet), and digital planning tools including the Deckplanner terrace configurator, Calculette, and project configuration tools for fences and facades. All composite products share a common technology platform: approximately 2/3 PEFC-certified French wood fibers combined with 1/3 polyethylene via extrusion processes (coextrusion for Atmosphère/Nuances, mono-extrusion for Élégance). The company operates an integrated circular economy model including Silvadec Fibres (wood flour production), Heuliad Environnement (plastic recycling), and the Recompose-it end-of-life recycling program. Manufacturing is based in Arzal, Brittany (France), with a second German facility planned in Bavaria by 2026.
