With the promotion of policies such as ultra-low energy consumption buildings,near zero energy consumption buildings,and zero carbon buildings,passive buildings are gradually realizing industrialization.The research of passive exterior doors is still in its early stages.Considering the uniqueness of passive doors as structural units,it is necessary to achieve the integration of insulation,fire resistance,and theft prevention,which poses new challenges to the manufacturing of passive doors.This paper takes the current situation of the passive door industry as the background,analyzes the technical parameters of passive doors,and provides a design scheme that combines insulation,fire prevention,and anti-theft performance.
