MULTILAYERED SHEET, HEAT PROTECTOR USING THE SAME AND MANUFACTURING METHOD OF THE SAME

摘要

The present invention relates to a multilayered sheet, a heat protector using the same, and a manufacturing method of the same. The multilayered sheet includes: a first heat insulation plate; a second heat insulation plate; and a third heat insulation plate placed between the first and second heat insulation plates, wherein an air gap is provided between the insulation plates. The third heat insulation plate includes a plurality of heat insulation protrusions having a T-shaped cross section, wherein an air flow space is alternately formed in forward and rearward directions. Therefore, the present invention improves the heat and sound insulation efficiency of a heat protector as multiple layers are formed into the multilayered sheet.
