The present invention provides a structure comprises: a secondary barrier which is located on the upper side of a lower insulation material; a first protective tape attached to the upper side of the secondary barrier; and a second protective tape which is attached to the upper side of the first protective tape and installed to prevent contamination due to an adhesive during a bonding work for an upper insulation material. The structure is provided to have a two-layer protective tape attached to the upper side of a secondary wall, thereby preventing the secondary wall from being contaminated by an adhesive during a bonding work for the upper insulation material, and to allow the two-layer protective tape, which is attached to the upper part of the secondary barrier, to be separately removed, thereby preventing the secondary barrier from being contaminated and facilitating a flexible secondary barrier (FSB) process being performed afterward. |
