What Should Exterior Insulation Do Beyond Thermal Performance?

The buildings and construction sector accounts for around 39% of global CO₂ emissions and nearly 50 per cent of global material extraction. Operational carbon emissions which are associated with the energy consumed to run the buildings also rose by 1% to 9.9 billion tonnes of CO₂ in 2024, even as building energy use intensity (EUI) has improved. These figures point to persistent gaps in the way bu
