In order to solve the problems of insufficient utilization of renewable energy

low utilization efficiency of existing energy

and poor energy-saving performance of the building itself in building wall energy-saving and thermal insulation construction

this paper combines technologies such as extruded polystyrene board pasting technology and glass fiber mesh treatment technology

and proposes measures including rational selection of external wall thermal insulation and energy-saving materials

as well as strengthening material quality control and base course treatment

with a view to providing references for improving the construction quality of building wall energy-saving and thermal insulation.
