Abstract
The vacuum insulator in accordance with the present invention comprises glass white wool body which density is 0.1˜0.5 g/cmin density and is below 0.0023 kcal/mh° C. in thermal conductivity, and a non permeable container surrounding the body in which the pressure is between 10˜10torr. The vacuum insulator is fabricated by piling up glass white wool, thermal-pressutizing the piled glass white wool to form a body of 0.1˜0.5 g/cmin density wherein the pressurizing is done at 0.007˜1.5 kg/cmand under 20° C. for more than 10 minutes, putting the body in the non-permeable container, and producing a vacuum in the container.
