Abstract
This study examines the practical significance of external wall insulation technology in building construction. The study emphasizes that external wall insulation improves occupant comfort and increases building protection, and should focus on materials and methods, using case study methods and thermal conductivity measurements. The main materials include polystyrene panels (EPS), extruded polystyrene foam panels (XPS), thermal insulation mortar, cement foam insulation boards and rare earth insulation materials. The results of the study revealed different thermal conductivities of different materials, and the same materials under different conditions. The moisture levels of insulation materials affecting the thermal conductivities were also highlighted. The conclusion showed that EPS and XPS were more suitable for use as external wall insulation in China. The necessity of selecting insulation materials tailored to specific environmental contexts points out that although insulation is promising, there should still be strict standards in construction.
