What ara thermik sl does
ara thermik sl (operating as Arathermik) is a privately held Spanish fenestration manufacturer and installer headquartered at Polígono Xoroxarta 13A in Irun, Basque Country, Spain. The company fabricates and installs custom-made aluminum and PVC windows, doors, glazing systems, glass curtains and enclosures, railings, and solar control products, serving residential homeowners as the primary segment alongside community/HOA building managers and a smaller set of commercial and hospitality clients such as Hotel María Cristina and Museo Oiasso. Operations are concentrated in the Basque Country with a cross-border extension into the French Aquitaine region, reflected in a bilingual Spanish/French website and a French sub-brand identity.
Arathermik's product technology is built around custom aluminum and PVC profile systems. The aluminum range includes thermal-break hinged systems (Classic 52, RS-77 CE), a proprietary exclusive aluminum window (Thermik 65 Plus) featuring a novel injected polyurethane system within the polyamide channel for enhanced thermal insulation in the Basque coastal climate, hidden-sash (ARS-72 HO) and lift-and-slide (GR) formats, sliding systems (RPT 67, Gernika), and a non-thermal-break line (A-40). The PVC range is centered on the Cor A-70 5-chamber profile system. Complementary offerings include interior glass partitions, glass curtains and terrace enclosures, garden doors, P-500 reinforced aluminum building entrance doors, solar control (louvers, shutters, awnings, blinds), and multiple railing variants. The company emphasizes same-day structural opening closure during window replacement to avoid overnight exposure of the property.
The business model is direct-to-consumer with no intermediaries: customers request a free no-commitment quote, Arathermik handles measurement, custom fabrication, and in-house installation by its own crews, and offers installment financing at approximately 90 EUR per month per window. The company also manages customer applications for Next Generation EU energy-efficiency subsidies and Irun municipal aid, embedding public-funding navigation directly into the sales process. Pricing is project-based and not publicly disclosed, and lead times from quote acceptance to installation run approximately 4–6 weeks at an installation pace of roughly 3 windows per day. Warranty terms are 3 years on windows and 10 years on main components, glass, and aluminum.
