Panelsan Cati Cephe Sistemleri Sanayi ve Ticaret AS is a Turkey-based building materials manufacturer specializing in the engineering, production, and distribution of insulated sandwich panels, thermal insulation boards, and exterior envelope systems for industrial, commercial, and agricultural construction. Founded in 2004 and headquartered in Ankara, Turkey, the company operates integrated manufacturing facilities and supplies architectural and structural building envelope solutions organized across primary product lines: polyurethane (PUR) and polyisocyanurate (PIR) core roof and facade sandwich panels for thermal insulation; rockwool and glasswool mineral fiber core sandwich panels for fire-rated and acoustic applications; expanded polystyrene (EPS) insulated sandwich panels; cold storage and cleanroom insulated panels and doors; expanded polystyrene (EPS) rigid thermal insulation boards, ceiling panels, and floor underlayments; custom-molded EPS protective packaging products for appliances and industrial components; integrated solar photovoltaic roof panel systems; and related structural flashings, ridge caps, and fastening accessories. Panelsan serves general contractors, industrial developers, pre-engineered metal building fabricators, logistics operators, and agricultural facility builders across Turkey and international markets, exporting to more than 20 countries spanning Europe, the Middle East, Africa, and Central Asia. In recent strategic developments, Panelsan expanded its international production footprint through its wholly owned subsidiary Panelsan KZ by forming the YDA-Panelsan LLP joint venture with YDA Insaat to build an insulated sandwich panel manufacturing plant in Kazakhstan's Astana Industrial Park 1, equipped with continuous production lines contracted from Germany-based Hennecke OMS. In addition, the company has secured state investment incentives to execute capacity expansion and modernization projects across an 81,000-square-meter site in the Polatli Organized Industrial Zone in Ankara, while commissioning a 2,015 kW captive rooftop and ground-mounted solar photovoltaic generation project in Elazig to lower operational carbon intensity and meet internal energy demands.
