Insulation for a better tomorrow

Welcome to URSA´s website

URSA is a company dedicated to the manufacture and commercialisation of thermal and acoustic insulating materials oriented towards sustainability and energy efficiency in building. The company enjoys wide commercial presence both in Spain and in Europe thanks to its 13 production plants, strategically placed over the European continent.


Today, URSA is one of the largest mineral wool and extruded polystyrene (XPS) manufacturers in Europe, two complementary insulating materials which contribute to insulate buildings thermally and acoustically.


URSA products help reduce buildings’ energy demand, mainly in heating and cooling, allowing users to reduce their energy consumption and, regarding sustainability, these products do not only contribute to final user comfort, but also lend a hand to the environment, reducing CO2 emissions, and to countries’ economies, diminishing fossil fuel dependency.
