Isover France and Switzerland technical director Jérôme Saulnier saud "The realisation of this revolutionary industrial prototype with fusion by immersed burners will make it possible to recycle glass wool in industrial quantities, transforming it into cullet. This cullet will be used in the manufacturing process of our insulating products and will also reduce our energy consumption, our carbon emissions and improve the life cycle of our products."

India: Knauf Insulation has donated and installed a 600m² insulative Urbanscape Green Roof at Piala Ashar Alo girls’ primary school in Kolkata, West Bengal. The roof includes a 2cm-thick layer of exposed mineral wool in which plants are able to grow. By retaining up to 47% of rainwater, the roof can help to prevent streets from flooding in the rainy season. Knauf Insulation’s Slovenia-based Urbanscape team supported the installation. The producer says that the renovation will protect learners from summer highs of 40°C and winter lows of 9°C, as well as seasonal dust squalls and downpours.

Head of building science Domen Ivanšek said “The flat surface of the 10cm-thick concrete roof was constantly hot, overheating the rooms below, and it was covered with a latex waterproof layer that was coming to the end of its life. When the school’s head said she wanted to provide the children with a place to learn about gardening and botanical science, it was clear that an Urbanscape Green Roof was the best solution all round.”
