There is also a thermal bridge effect in the vacuum insulation panel, and the thermal conductivity at the edge of the vacuum insulation panel is often higher than that at other locations, thus causing the thermal bridge effect. Therefore, how to reduce the thermal bridge effect of the vacuum insulation panel is a problem which needs to be solved urgently at present.
