What Atrya does
Atrya is a privately held, family-owned French industrial group founded in 1980 (originally as TRYBA) and headquartered in Schweighouse-sur-Moder, Alsace. The group designs, manufactures and installs PVC, aluminum and wood windows, doors, shutters and verandas across five European production sites located in France, Switzerland (Palézieux, Oron-la-Ville, Basel region) and Portugal (Ribeirão, ACWIN's 50,000 m² facility). Core technology centers on automated extrusion and assembly lines, robotized machining centers at ACWIN Portugal, and a vertically integrated aluminum finishing chain via the wholly owned SLA Industrie coating subsidiary (2.5 million meters/year capacity, Qualimarine QM-050 licensed since 2013). Revenue reached €360M in 2023 and €351M in 2024 with approximately 800 employees including participations.
The group's go-to-market is multi-channel. To building professionals and trade customers it operates through distribution networks (AMGO), independent reseller/carpenter networks (AMCC) and a direct concessionnaire network (ISOFRANCE, 28 points of sale). Consumer-facing channels include the CLOSY brand as exclusive DIY fenestration supplier at Leroy Merlin and direct end-customer sales through concessionnaires. The wholly owned energy subsidiaries — TRYBA Energy (photovoltaic project developer and operator of 300+ PV plants), TRYBATEC (water/heating metering in collective housing, since 2016) and TRYBA Solar (residential self-consumption PV, launched 2024) — extend the addressable market into renewable energy and building energy services. B2B fenestration operations were partly spun off into AT Partner (51% to director Lars Platow in 2018, projected €150M revenue in 2025), and the group holds a 49% strategic stake in Iberian PVC leader Caixiave (acquired 2019).
In 2025 the group sold its French and Belgian TRYBA window operations to DOVISTA, signaling a strategic refocus onto Swiss and Portuguese window manufacturing, the energy vertical, and transversal services (SLA Industrie, Atrya Management). The senior leadership comprises founder-president Johannes Tryba, group CEO Stéphane Delplancq, group CFO Semra Sernic (heading Atrya Management SAS), Swiss operations director Pierre Nuss and SLA director Pascal Fischer.
