Recently, construction method and form system are gradually simplified according to the deficiency of human power and the increase of construction cost. The form system as a temporary structure needs many workers and includes many dangerous factors during installation and removal. Therefore, this study presents the permanent wall form system to provide the two functions of form and insulation, and to simplify the installation process without removal works. This wall form system consists of the double insulation materials and metal web for the security of safety, insulation and soundproofing. For the field application of this form system, the safety and serviceability of the form should be secured. To this end, this study evaluates the lateral pressure capacity of the system through the structural experiments considering actual field conditions.
