Inrialsa

What Inrialsa does

Inrialsa, founded in 1966 and headquartered in Lardero, La Rioja, Spain, is a privately held fenestration manufacturer operating across two divisions: PVC windows under the Ecoven Plus brand and aluminum windows under the Cor series (Cor 80, Cor 4600, Cor 4700, Cor 4900) plus the Alu Steel hybrid line. The company employs 28 people and runs two specialized factories totaling more than 20,000 m² of production and logistics space, one dedicated to aluminum and the other to PVC systems. Its products incorporate thermal-break technology with tubular polyamides, crosslinked polyolefin gaskets, and Passive House-compatible performance (e.g., Uw from 0.65 W/m²K on the Cor 4600 Plus lift-and-slide; Rw up to 46 dB acoustic insulation), positioning it in the energy-efficient fenestration category.

The company sells primarily through a direct quote-based model via its website budget request, supplemented by a regional Spanish installer network. Customers named in project references span hospitality (Brial Alfajería Suites) and residential/construction (Aeris Building, Barakaldo, Franco López). Pricing is not publicly disclosed; contracts appear to be project-specific. In 2023-2025 the company accumulated a notable ESG regulatory footprint — first in the Spanish window sector with the AENOR N Sustainable certification (2023), AENOR Residuo Cero (2024), and the Premio Mercurio Sostenibilidad (2025) — using these credentials to access sustainability-driven construction tenders.

Inrialsa serves construction firms, developers, window installers, and sustainable-architecture projects across Spain, with a geographic footprint concentrated in La Rioja and the Basque Country. The business is independently owned with no disclosed institutional investors, parent company, or public listing; revenue, ownership structure, and financials are not publicly available.
