What began as a one-off roof renovation at Belgaid secondary school in Oran, Algeria, has grown into a large-scale energy-saving initiative. Over 220,000 m. of buildings, including schools, hospitals and homes across the country, have since been insulated with Airium™ mineral foam, resulting in annual energy savings of 12.21 million kWh and preventing 5,104 tonnes of CO2 emissions. This groundbreaking material, with an average thickness of 12 cm, improves thermal comfort by up to 2°C during winter, with up to 61% reduction in heating needs and 45% lower cooling demands, translating to significant energy savings.
Airium, in its roofing systems application, has now expanded beyond Algeria and is now available in Morocco, Jordan, Mexico, Oman, the UAE, Qatar, and Poland, bringing significant environmental and energy benefits to these regions.
The building sector is responsible for nearly 40% of global energy use and generates 33% of the world’s greenhouse gas emissions.1 Despite advancements in insulation, many older buildings — like the 85% of European structures built before 2000, of which three-quarters have poor energy performance2 — still lack sufficient energy efficiency. Enhancing the insulation of buildings can dramatically cut energy consumption and reduce carbon emissions, as it requires less energy to maintain comfortable temperatures—both in winter and in summer.3
In Algeria, the annual energy consumption more than doubled over the last 20 years, rising from 305 TWh in 2004 to 705 TWh by 2023, while 99.73% of the country’s energy still came from fossil fuels that year.4 Nearly 30% of the nation’s total energy consumption goes to the residential sector, with 70% of that used for heating and cooling.5 Innovative insulation materials are key to significantly lower energy use, directly addressing the growing demand for heating and cooling, and the need to reduce fossil fuel reliance.
We chose Airium for its ease of use, lightness, and ability to eliminate thermal bridges, providing better thermal comfort. It replaced two materials at once, making our project more efficient.

Airium™ mineral foam is a cost-effective, on-site produced insulation for new builds and renovations. Its mobile production unit minimises waste, while providing continuous insulation without thermal bridges. Four times lighter than traditional (polystyrene) materials, Airium™ is also easy to recycle, making it an environmentally responsible choice for large-scale projects.
