<p>PROBLEM TO BE SOLVED: To improve working efficiency by efficiently and appropriately performing construction work of a shielding body for shielding from outside, a space in which a person can enter and leave, for example a vacuum insulation material to a wall of an architectural structure, and construction work of a finishing material all at once.SOLUTION: Each of heat insulation mats M is formed in the shape of a rectangular flat plate so that the heat insulation mats M can be aligned and arranged in the longitudinal and lateral directions on one surface Wf of a shielding body W and is joined with the one surface. The heat insulation mat M includes: a vacuum insulation body I formed in the shape of a rectangular flat plate; a surface finishing material A joined with a surface Ia of the vacuum insulation body I and covering the surface; a flat and extensible protective sheet B joined with a rear face Ib of the vacuum insulation body I and covering the rear face. The protective sheet B can be joined with the one surface of the shielding body W. The vacuum insulation body I includes: a rectangular flat plate-like core material C having heat insulation property and air permeability; and a sealed bag body F which is a non-permeable membrane body, is formed in a flat bag shape, and stores the core material C inside thereof. Moreover, the inside of the sealed bag body F is vacuumed substantially into vacuum while the core material is stored in the sealed bag body F.</p> |
