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.”
