Experimental Evaluation of Thermal Insulations Materials Used in Building Sector to Achieve the Objectives of the National Determined Contribution

The use of thermal insulation proves to be a highly effective strategy for energy conservation in building structures. Thermal insulators play a crucial role in both the construction of new buildings and the renovation of existing ones, enhancing their energy efficiency and ensuring better thermal comfort. In Algeria, a significant challenge persists owing to the limited availability of companies and specialists dedicated to the execution of thermal insulation. To address this issue, it is essential to augment the number of thermal insulation companies and enhance production capacity. This expansion is pivotal for realizing the goal of improved energy efficiency by 2030. This study is dedicated to the investigation of the thermal properties of three distinct thermal insulation systems: lightweight foam concrete (LFC), expanded polystyrene (EPS), and polyurethane (PU). The primary objective is to comprehend and integrate these materials into new building programs for housing and the renovation of older structures.
