SIA Poliurs

What SIA Poliurs does

SIA Poliurs is a Latvian privately held industrial manufacturer founded in 1991 and headquartered in Ozolnieki, Jelgavas novads, Latvia, specializing in pre-insulated pipe systems for district heating and district cooling networks. The company operates a single vertically integrated factory with 85 employees (75 production personnel, 24 office/management staff), manufacturing a complete portfolio of steel media pipes encased in hard polyurethane (PUR) foam insulation with outer PE or steel jacket pipes — covering single pipes, twin pipes, special pipes (including stainless steel, PE, PVC, and copper media variants), bends, T-pieces, valves, fix points, and joint components. Its technical differentiators include proprietary moisture-monitoring technology (the Nordic alarm system with pulse-meter fault location connectable via copper, fiber, GSM, or internet), proprietary joint technologies (double sealing, double expanded, and electro-welded sleeves), Zebra foil-marked cutting pipes, and a high-temperature PIR foam product line launched in 2021. All components are developed and manufactured in-house without subcontractors.

The company generates revenue primarily through B2B hardware sales of pre-insulated pipe systems, fittings, and components, supplemented by professional services including installation consulting, training, and construction supervision. Its go-to-market is enterprise field sales targeting district heating and cooling utilities, construction contractors, and industrial customers through direct frame agreements with major Nordic and European energy companies (Stockholm Exergi, Fortum, E.on, Sinfra, Vattenfall, Veolia) and through channel partners Arvo-Putki OY (Finland) and Aterm Tubes (France). It holds a comprehensive certification stack — ISO 9001, ISO 14001, CSTB QB19 (France), Euroheat & Power EHP/001, RISE EN 253 annual testing, AGFW (Germany), ISO 14025/EN 15804 EPD, and 100% renewable electricity certification — which functions as a regulatory moat for public infrastructure procurement. Customers span 20+ countries across Northern, Western, Southern, and Eastern Europe, the Middle East, and North America, with notable reference projects including a Microsoft hyperscale datacenter cooling deployment in Espoo, a 25 km Swedish pipeline, a 2.5 km Dn800/1000 Vilnius project delivered in two months, NEFCO-funded reconstruction in Ukraine, Qatar World Cup district cooling infrastructure, and an 800+ km Spanish district heating network contracted for completion before 2030.
