The economic sectors have a significant impact on the environment and energy consumption. The building industry is responsible for a significant amount of energy consumption and greenhouse gas emissions. However, building insulation is a practical solution to reduce energy consumption and carbon emissions. Building insulation involves adding materials to the building envelope to reduce heat loss or gain through conduction, convection, and radiation. Insulating roofs, walls, and floors can significantly reduce the energy required to heat or cool a building, resulting in lower energy bills and a more comfortable indoor environment. Therefore, building insulation is vital for sustainable development and reducing the carbon footprint.
